Autoclimate Control Issue?

[GreenDragon68]

Hi,

 

I'm a new owner of a 2011 Edge Sel AWD base model. No MyFord Touch system. There seems to be some issues with the auto climate control system in the car, unless it's new technology that I'm just not used to. I'm coming from a 93 Chevy truck. I'm hoping some others out there without the touch system can help.

 

Whenever I turn the car on the climate control system is on. The auto button is not selected. If I turn off the climate control and then turn off the car, when the car is turned back on the climate control is on again. It's like it forgets that it was turned off. Is this normal or is that considered part of the auto climate system even if the auto button is off?

 

Also, I noticed that at times I'd set the temperature to say, 68 degrees, and the air would come out warm from the main vents. If I turn it to defrost it comes out cold. However, there's has been times when I've kept the same temperature and it's cooler air coming out of the vents. Again, is this something that should be checked out or is it coming out cooler because the outside temperature is warmer? I'm hoping that warm air will come out for defrost on those cold mornings.

 

Lastly, is there a temperature that you suggest best for hot or cold weather?

 

Thank you for all your information!

Turning back on when you start the car is probably normal but it's hard to say for sure unless the owner's manual describes it. What did the OM say?

 

I believe what's happening with defrost is that you have 2 modes - automatic and manual. When you set the temp to 68 and you're in automatic mode it will warm up the interior to 68 so you'd get warm air if it's below 68. When you switch to defrost you're in manual mode and 68 becomes the actual air temp. Try putting the temp on 80 or 85 when selecting defrost and see if that warms up the air. If not then it's probably defective.

Akirby,

 

Thank you for your reply. I did look in the OM bue it doesn't mention anything about the system turning on automatically. It's pretty vague actually. The only mention is with the auto mode set to on.

I'll have to play around with it some more. This morning it wasn't as cold as other days have been so maybe that's why 68 didn't feel as warm and it was cooler air with the defrost. But a few nights ago the defrost was definitely pretty warm when set to 68. I'll try as you suggested about increasing the temperature. I did notice a few times that when set to a temp it was warm and then cooler lateron. But I would think being on manual mode it would just keep pumping out the same temp and not changing regardless of interior temp. The whole auto/manual is pretty confusing considering the manual doesn't explain it well at all. OR it's just defective as you said and it's not working properly.

 

Thank you!

I notice exactly the same issue with the defrost. I know with Def ON, most vehicles will only take air from outside as it is too hard to remove all of the moisture from inside air. This may be the issue. I find it only noticeable when the temp isn't that cold outside i.e 15C / 60F, the heater doesn't warm up the outside air as much as it does if you have any other setting enabled, likely these setting are using more internal air and it doesn't take much to heat them up, thus the defrost setting is colder, even when you have it set to Def and Floor. If its very cold, the heater turns up and is warming the air enough that it doesn't come our cold anymore, although still not as warm as the other settings.

 

All of the above, it just a theory, but I've been testing this out and it seems to be valid, not sure on my reasoning, but the results are always the same.

 

This is another thing Ford needs to review in the computer.

[Waldo]

Just think of the system like the thermostat in your house. The temperature you set it to is the temperature you want in the car, it has no relation to the temperature of the air actually coming out of the vents. The car uses temperature sensors inside and outside the car to determine what temperature of air to put out.

 

Ford designs their systems to operate normally when set at 72 degrees. If you have it set to 68, it thinks you want it pretty cool inside, so it will tend not to put out much hot air.

 

Defrost gets a bit complicated as it forces open the recirc door (allowing only outside air). It also will use the A/C compressor, even when it's cold outside.

 

I imagine the system is programed to turn itself on every time you start, just to avoid the possibilities of carbon monoxide poisoning, since with the system off there is no fresh air entering the vehicle.

 

Personally I just set to 72, hit auto and forget about it.

[AXCL]

I haven't put a second thermometer in the car to verify, but I can guarantee that if it is around 60F outside and I have my temp set to 72F, while using the defrost, the internal temp will not be 72! It will be more like 65 or less. This is 20-30 min driving so everything has had plenty of time to warm up. As soon as I switch over to the standard vents, it gets nice and toasty! There seems to be an outside temp range where the Def doesn't add enough heat to meet the internal temp setting. I've driven 20 min like this and had frozen feet and hands by the time I got home.

Hi AXCL. :D Waldo gave a good explanation, but it is difficult to get across. The best way to try and understand is to read the Owners Manual instructions concerning how to operate the HVAC system, but I will give it the old college try anyway:

 

If you want the HVAC system to get the interior to the set temperature (e.g. 72*), you must leave it set to "AUTO". Do not then hit the front "DEFROSTER", "FLOOR", the dash registers or any other button to redirect air. Also, do not change the fan speed.

 

The reason you can't hit those buttons is actually simple: Once you change the setting to "DEFROST" (front), "FLOOR", "VENT" etc., or change the fan speed to anything other than what "AUTO" ran it, you defeat the "AUTO" settings and the system will only blow 72* air out of the corresponding registers. Essentially, if you hit those buttons, the system thinks you don't want it running on "AUTO" anymore.

 

So if you want the interior of the car to be held at 72*, set the system to "AUTO", set the temperature to 72* and do not touch any other HVAC system buttons. If you do, the system will only blow air out the particular registers at the set temperature, which will not heat or cool the car to that set temperature and keep it there. It will only blow 72* air.

 

And as you have witnessed, blowing 72* air on a 60* day will only get the interior temperature up to about 65*. And the colder the day, the worse it will be. Leave it set to "AUTO" and touch nothing. Also, "AUTO" will normally give enough dry air to the front windshield, either through the defroster registers or by generally drying the cabin air, to keep the windshield clear.

 

In addition, keep in mind that all of the following settings will enable the A/C compressor, whether set for heat or cold: "AC", "AUTO" and the front defroster. So all three will normally adversely affect fuel mileage.

 

But again, this is all explained in much better detail in the Owners Manual.

 

Hope this information helps.

 

Good luck. :beerchug:

Great explanations all.

Just do AUTO and have trust in it.

 

There may be a time when heavy breathing will require a hit of the defrost button but just remember to go back to auto when you've calmed down.

(also note that defrost often turns the AC on to help in the removal of excessive moisture)

[AXCL]

You guys all seem to be having great luck with AUTO, so I tried it again this morning and even set it prior to shutting the Edge off last night. NO GO! It functioned exactly as you said and the way I understand it as well, except it didn't get hot. It appeared to use the DEF/Floor setting for most of the 30 min trip in 32F. I had it set to 72F and my wife and I were cold, again, I don't think it got above 65F.

 

What I normally do is hit AUTO, then control the location, but don't touch the FAN, leaving the FAN on AUTO. I believe this should do the same thing as the FAN does speed up and slow down once the truck gets warm, so this must also control the inside temp by blowing more hot air if needed as in the morning, even with this setting, the air is way above 72F until it warms up. If I use the Floor or the main Vent settings I'm find and I get to my nice 72F. I've read the entire manual and have just reread the HVAC section now to ensure I didn't miss anything, I couldn't find anything in the manual that stated that the air will only come out at 72F if you set it to 72F. Even when nothing is on auto, it will blow hot (well above 72) air if needs to bring up the temp considerably. This is easy to test. On a cold day, once your engine warms up, override your fan to low. You will feel air is as hot as it will get, but it won't blow enough to get the inside warm. Alternatively, if your inside temp is almost warm, crank you fan all the way up. You'll feel the air temp come down a bit once it reaches its set temp. This one is harder to notice.

 

I believe as long as you don't touch the FAN speed, the temp setting should work. I completely understand that if you touch the fan and its not high enough, then you'll never get the inside warm. But on the same note, I've tested having the fan on high and the air temp changes as well. So no matter what setting you have it on, it will try to get the inside temp as close as it can to the set temp. If you have the fan set to an extreme, or all floor or all def, then your right, it will take a while, if it ever gets you to the temp you asked it to, but it will try.

 

My issue is ONLY when the system uses the DEF or DEF/Floor, no matter if it is AUTO, AUTO fan, or full manual. I've tested this thing every which way but loose! I'm sure I could write the manual on it by now, but with these settings, it no worky!...too cold. My heated seats don't turn on with the remote start either, so this may all be related, perhaps my temp calibration is all F'd up, or I have a bad sensor somewhere.

 

I've also tried researching the 72F theory as Ford's correct setting. The manual only point to 72F during the remote start. Your climate control is not on yet so it uses this as the base temp and heats or cools to this point based on the current ambient temp. Once you go to a full start, 72F is irrelevant as it is now controlled by your previous climate control settings and in theory, your interior temp should adjust exactly to that temp pending it can based on your other settings. i.e. low or off fan.

 

P.S. I love this forum! I had a Rogue before and the forum sucked, first off, there was 1 post a day and those who did post, shouldn't have. This group is much more knowledgeable and in most cases, if its on the forum its worth reading. I've only had an Edge for 2 months, and I have learned a lot from everyone. I guess the Edge has more of an enthusiast following.

 

Cheers to all who post! :beerchug: :party:

Everyone,

 

Thank you for all your prompt responses and information! I feel your explanations are much better than the manual. This is a great forum. I'm so used to just manually controlling the heat/cold in my older vehicles that I'm a creature of habit. I'd rather just run it manually as I don't need the fan blowing all the time and just turn it on when needed. But I did notice as AXCL pointed out that my defrost blew out hot air last night. The temperature was much colder than the morning. Had it set at 72 in the morning (It wasn't that cold yesterday. Lots of rain) and no warm air out of defrost. Last night it was 38 and it blew out the warm air on defrost. So it does indeed look like there is a sensor for the outside temperature. I'll have to work with it some more. Havn't really used AUTO setting yet so I'll have to give that a go as well. As long as I get some hot air coming out of defrost on cold days when there's some ice buildup on the window I'll be ok with it.

 

Thanks again!

Hi AXCL. :D A lot of information, so I will address what I can (hopefully in an understandable manner). First, out of curiosity what year is your Edge ( I am assuming a 2011) and which of the three EATC systems is your Edge equipped with? Next, just to correct this misconception upfront: It is a fact that on a properly operating Ford EATC HVAC system, the full "AUTO" function is disabled if any of the directional or fan speed buttons are pushed. Pushing those buttons means the driver is now manually controlling the system. So if you change the settings to "Defrost" (again, only front), the floor, defrost/floor, dash registers etc., or change the fan speed, the "AUTO" setting is disabled.

 

As an example: In the Owners Manual, for all three EATC systems in the 2011 Edge, the descriptions for the front "Defrost" button operation all end with some variation of this phrase "To return to full automatic control, touch AUTO.". That is because pressing the front defrost button takes the system off "AUTO". The same goes if you redirect the air manually through any of the other register settings In addition, if you read the descriptions for the "AUTO" setting, they all are some variation of this, "AUTO: Touch to engage full automatic operation. Select the desired temperature using the temperature control. The system will automatically determine fan speed, airflow distribution, A/C on or off, and outside or recirculated air, to heat or cool the vehicle in order to reach the desired temperature.". So as you can see, in normal use, there should (usually) be no need to hit the front defrost or any other directional or fan speed button, as the system will make necessary changes automatically. If it does not, there is some sort of underlying issue that needs diagnosis. If you do need to use full front defrost for heavy ice etc, then once the need for the full front defroster is over, you need to hit "AUTO" at some point to regain full "AUTO" functions. If you don't, the interior temperature will not get to your set temperature on a cold day.

 

Now, to your particular issue: It is entirely possible that you have some sort of EATC issue. But there are so many variables thrown into the mix with the new MyFord/MyFordTouch interface, the remote start system and the fact that we can't actually see what is happening that your best course of action is probably (unfortunately) to set up a Service appointment to have this issue diagnosed and corrected if necessary. While it is not anyone's first choice to revisit the Dealer, in this way you can explain and demonstrate the issues to the Techs first hand. And the Tech can examine things first hand. At this point, all any of us can do is take well intentioned educated guesses

 

Just so you understand, I am not trying to discourage you from asking questions here. I am only trying to point out that your system is either working correctly, or it is not. If it is working correctly, then this is just a matter of you gaining a better understanding of how the system works. The new MyFord/MyFordTouch systems can be hard to understand in the beginning. However, if it is not working correctly (possibly due to a MyFord/MyFordTouch teething issue?), then no matter what we come up with a Service visit will be necessary, so why not get it done sooner than later (only my opinion, of course). If you bring it in, explain your concerns and it winds up that the system is working correctly, it still will cost you nothing and the wondering will be over. Again, for what it is worth this is only my opinion.

 

Hope some part of this information helps.

 

Good luck. :beerchug:

bbf2530,

 

Great explanations all around! I'm not sure if AXCL has the same exact system I have but it sounds like he does. I just have a base model SEL AWD. So it doesn't have seat heating or the Touch system. I'm curious though in your experiences, if you are using the system manually and you shut it off. Does it turn on again automatically when you start the car? As mentioned I'm just using manual mode now because I'm a stubborn creature of habit. But if I turn off the system and turn off the car, when I turn it back on the climate system is back on with the fans blowing. The fans are also at a different setting than I set it before it was turned off. This is with AUTO mode turned off. The temp stays the same as originally set though. Almost like the car is forcing you to use the climate control even if you don't want to.

Hi BBF2530,

 

Thanks for you detailed replys!

 

To answer your question, I have the 2011 Edge Sport w/ Mytouch, which leads into the service comment. The answers I'm getting from my dealer are that most of my issues will likely be addressed in the infamous update many of us are waiting on. I'm in IT, so I completely understand the software side of things and agree that they are likely right and may spend hours trying to chase an issue they can't resolve without the update. They have my issue list so, at least its logged at this point. If it was not working at all, I'd make a bigger stink about it, but I can make it a sauna if I want, just not with the DEF on and set to a normal temp.

 

I think we agree that If I use full 'AUTO" and my internal temp doesn't reach what I set it to, then something is wrong. I do think we have a disconnect on how the system does or should work. You sound like you know a lot about the Edge and the ETAC and from that I certainly would not take my theory over you knowledge, but I'm looking at the climate control in the same way as a basic heating unit. If you set a home heater to 72, but set the fan low, it will take a lot longer to reach 72 and may not get there, but will keep trying. The air isn't blowing 72, it blows "hot" air, what temp is irrelevant as long as it is above ambient temp and can out put it in a large enough volume, to heat the air faster then the air will cool. (thus your comment on if it blows 72, it will never heat up to 72 if the outside air is 32), but if designed correctly, it should never be blowing 72 when I set 72, it should be more like 80. With the Mytouch, I have the ability to have the fan on AUTO, while still manually controlling the vents. I don't see why using it this way should SIGNIFICANTLY effect the Climate controls ability to reach the correct temp, or as I understand you are stating, disable the validity of the temp setting. Again, this is just based on theory! You seem to know the unit inside and out so, but I don't see anything in the manual that would make me think otherwise, and to me, it wouldn't make sense if it did. Also if this wasn't the case, what would the AUTO fan run based on? The fan speeds up or slows down depending on the ambient temp...doesn't it? Perhaps the ETAC doesn't do this, but that just seems like poor designing then.

 

Again the above is all theory and how I think it should work, not saying it does do this, but I would be surprised if it didn't.

Hi BBF2530,

 

Thanks for you detailed replys!

 

To answer your question, I have the 2011 Edge Sport w/ Mytouch, which leads into the service comment. The answers I'm getting from my dealer are that most of my issues will likely be addressed in the infamous update many of us are waiting on. I'm in IT, so I completely understand the software side of things and agree that they are likely right and may spend hours trying to chase an issue they can't resolve without the update. They have my issue list so, at least its logged at this point. If it was not working at all, I'd make a bigger stink about it, but I can make it a sauna if I want, just not with the DEF on and set to a normal temp.

I have a 2011 LTD edge and the car does seem to warm up ok, I usually just leave it on auto and noticed that the vents rarely blow on my face i.e. the dash vents are not really on at any given time. The Door vents and I floor vents do have warm/hot air coming out of them, but If I set the vents to the face/floor position I do have warm/hot air in my face like I should. But If I reach behind the center console, the vents seem to be blowing cool air in the back? Anyone been able to figure out a way to get the back vents of the center console to blow hot air? Overall the car does feel warm, so I'm not complaining, but my older manual systems always blew the same temp air over all the vents..

[krash67]

I have a SEL AWD w/ MFT and my experience with the HVAC is a bit funky and I wrote to SYNC support about it and suggested some tweaks for the next upgrade.

 

At first I didn't think my Remote Start climate settings were working as I had 1" of snow on the truck and outside morning temp was 3C (37F) and the front and rear defrost and heated seats didn't turned on. Eventually, I figured out the threshold to kick in the remote start auto climate settings is the outside temp as to be at least -1C (30F). For folks that live in high altitudes or next to the Great Lakes, the outside temp is much colder then it really is. Or in my case, it was way below zero overnight while the snow fell but we had a warm Chinook wind come in during the morning after the sunrise. My suggested tweak was the ability to change the threshold temp for remote start in order to adjust for these variances. I think it is should be easy to program into the system since after all it is a touch UI just like an iphone.

 

In terms of the Defrost setting, that sucker pumps a lot of hot air and I love it, the side windows are pretty much cleared and dry within 5 to 10 mins of driving in -20C weather. In -30 to -40 temp, the defroster was able to keep the windows from frosting over again but unfortunately I was cooking in there and open the window to cool off. This is a huge bonus for me as my previous Jeep Grand Cherokee could never defrost my windows in extreme cold weather.

 

I find the auto setting and the temp set at 22C (72F) feels more like 18C so I set it at 24C (75F) and it feels more like a comfortable 20 or 22C.

 

The one thing I don't think they can fix is the windshield vent doesn't blow the air low enough on the windshield as ice starts to build up underneath the blades. It's a pain driving when it is snowing. I am going to enquire about the blades shaker which may fix this issue. It doesn't came standard on Canadian SEL

 

Except for the funky issues I mention, I am very impressive with the Edge's Climate.

Hi AXCL. Thanks you for understanding that I am only trying to help.

 

The short story is pressing any air redirection or fan speed button will take the EATC system out of "full auto" and hamper/alter its ability to warm (or cool) the cabin to a set temperature. It also locks in certain settings that you did not hit buttons for (runs in a partial auto/non-full auto setting). And the larger the variation between the exterior ambient temperature and the temperature the driver sets the EATC system to, the worse this effect will be. This is how Ford EATC systems (and most automotive EATC systems) are designed to operate. By definition, "AUTO" is auto and once you manually choose a setting other than "AUTO" by redirecting air direction or volume, the system is no longer controlling all functions automatically. So it is not operating in/with full automatic function and all bets are off concerning cabin temperature control. We can either leave it in full "AUTO" (and don't touch any other HVAC buttons changing airflow) or have manual control of one sort or another thereby disabling full auto operation. But we can't do both at the same time. :stop:

 

Now, if that explanation doesn't cut the mustard or walk the bulldog, then with a "VERY LONG REPLY WARNING" given in advance, read on. But don't anyone say I did not warn them.:

 

AXCL, your theory/theories are based on some basic misunderstandings of the EATC system in general and an idea of how you would like the system to work, not how it actually works. My explanations are based on how the system is designed to work, how it actually operates if operating correctly (keeping in mind possible MyFord/MyFordTouch/other production glitches in mind) and how it is actually explained in the Owners Manual. So what I explained above in previous replies and what I am explaining below is based that assumption that your EATC unit is working as designed and does not have some sort of glitch that will be addressed by software updates.

 

If you reread my [previous reply, you will see that I quoted several passages from the Owners Manual which answer your questions. For the sake of clarity, I will quote your questions/statements, then answer them. And I will certainly try to quote each question in context. Again, please keep in mind that I am only trying to help.

 

1 - "I think we agree that If I use full 'AUTO" and my internal temp doesn't reach what I set it to, then something is wrong." - Yes, we absolutely agree on that. Therefore, what I would like you to do is use the system set to full "AUTO" without touching any other redirect or fan speed buttons on a drive that lasts longer than sat, 20 minutes. Do this on two drive days. If the system warms the cabin up properly, then we have solved the "problem" as being a simple misunderstanding of how the system operates.. If it does not, then your EATC is not working correctly.

 

2 - "Again, this is just based on theory! You seem to know the unit inside and out so, but I don't see anything in the manual that would make me think otherwise, and to me, it wouldn't make sense if it did." - I quoted several passages in the Owners Manual that explain how pressing the "Defroster, fan and other buttons take the system out of "AUTO. I will do so again below to answer a few of your individual questions.

 

3 - "With the Mytouch, I have the ability to have the fan on AUTO, while still manually controlling the vents." - No, you are mistaken. You don't have that ability. That is the major cause of our disconnects concerning on how the system works/is designed. It is actually very simple. While you have the ability to make changes, making those changes takes the system out of full automatic mode so it can no longer efficiently regulate the cabin temperature setting. THis entire discussion really boils down to that. The EATC will only automatically (and efficiently) regulate the overall cabin temperature if left on "AUTO" alone. Once you change any setting, you have manually altered the settings and by definition it is no longer on "AUTO". The only way the system works on "AUTO" is to set it to "AUTO" and leave it there. Hit no other buttons redirecting the air or changing the fan speed. That is why I stated in my previous post (and quoted the Owners Manual), "...for all three EATC systems in the 2011 Edge, the descriptions for the front "Defrost" button operation all end with some variation of this phrase "To return to full automatic control, touch AUTO.". That is because pressing the front defrost button takes the system off "AUTO". The EATC system will not automatically (and efficiently) regulate cabin temperature until you press "AUTO" and return control to the EATC system.

 

4 - "...but I'm looking at the climate control in the same way as a basic (home) heating unit. If you set a home heater to 72, but set the fan low, it will take a lot longer to reach 72 and may not get there," Sorry for the partial quote, but this sort of cuts to the heart of the matter. You need to put that thought out of your head. An automobile system works differently than the home system you describe. In fact, not even all home heating systems work as you described. And even if the Ford EATC did work the same way, you answer your own question with this part of your quote. "it will take a lot longer to reach 72 and may not get there". Exactly, and in the case of a car, it will not get there for several reasons. Cars are not insulated as well as homes. The passengers are sitting less than 1 foot from major glass surfaces (extremely poor temperature insulators). Try this experiment - On a below freezing day, sit in your home for an hour about a foot away form a large window. You will feel much colder than what the rooms ambient temperature is set to. You will feel much colder than you will if you were to move only 6 feet away from that window. Another example (can't perform this test in a baseboard hot-water heated home, unless you shut water valves): Let's say you have a two (or multi) floor home. Block all the first floor heat registers so that only the second floor gets heat. Obviously, the first floor of your home will certainly get colder than the desired temperature, since heat rises and will not fall. Well, this is similar to only having heated air come out the defroster vents. The heat is directed up and will not efficiently reach the passengers. Plus, in your example, you have the system locked in at blowing 72* air once you took the system out of full "AUTO" by pressing the front defroster button.

 

5 - "..but I don't see anything in the manual that would make me think otherwise, and to me, it wouldn't make sense if it did. Also if this wasn't the case, what would the AUTO fan run based on?". Sorry for the repetition and again, for the partial quote. I separated this into two a=sections for the sake of clarity. You seem to be looking for something in the Manual which states something similar to, "Warning: If while the "EATC" system is set to "AUTO", you press any button which redirects the air or changes fan speed, the system will no longer work automatically to control the cabin temperature to the setting displayed on the unit". Well, yes, you re correct that it makes no statement similar to that anywhere in the Owners Manual. So on a stretch, we could fault the Owners Manual as perhaps being a bit vague. However, the "AUTO setting is described in this direct quote taken from the Manual (which I also included in my previous reply) - "AUTO: Touch to engage full automatic operation. Select the desired temperature using the temperature control. The system will automatically determine fan speed, airflow distribution, A/C on or off, and outside or recirculated air, to heat or cool the vehicle in order to reach the desired temperature.". Again, by definition, when combined with the previous Owners Manual quote stating, "...for all three EATC systems in the 2011 Edge, the descriptions for the front "Defrost" button operation all end with some variation of this phrase "To return to full automatic control, touch AUTO.", it becomes clear how the system operates.

 

6 - "I don't see why using it this way should SIGNIFICANTLY effect the Climate controls ability to reach the correct temp, or as I understand you are stating, disable the validity of the temp setting." Again, asked and answered. Taking the system out of "AUTO", by definition, significantly reduces the temperature control efficiency. The EATC system uses specifically placed interior and exterior temperature and sunload sensors to control cabin temperature. If you manually change where and how the air is distributed, the system, is no longer controlling what occurs, so how can you expect it to automatically control things. Again, a car is not insulated like a house. Turn off the heat in the house on a cold day and it will take a full day (and likely much more) for the interior temperature to reach the ambient outside temperature. Turn off the engine and heat in a car and the interior temperature will equal the exterior in as little as an hour (or less). The interior of a car is a very extreme environment,t so therefore the HVAC system is designed to regulate that extreme environment in particular ways. Also, when heat in a car is called for by the EATC, it will generally direct most heat to the floor registers (remember, heat rises). Yes, it will direct flow to the defroster vents, the dash vents or mix things up according to what is needed at the moment, but optimal passenger comfort is achieved by having heat directed to the floor vents (again, heat rises). Manually set the system to front defroster registers only and you screw things up (to put it bluntly) by directing all heat flow up high, leaving you and your passengers feet, legs and bodies in the cold. Yes, of course the cabin will eventually fill with warmer air if the fan is also set high enough, but the warmest air will be up high, with only air that is cooling/cold falling into the footwells (cool/cold air drops). So humorously put, you wind up with warm hair and a cold body, legs and feet.

 

You have to look at it this way. The EATC system gives you great setting flexibility. Among other things, you can:

1 - Set it to "AUTO" and have the system itself automatically/completel/totally control the ambient cabin air temperature. The EATC will automatically decide which registers to use, what fan speed to use and what air temperature is necessary at any particular moment in time according to circumstancesthe EATC system chooses.

2 - You can set it to a particular temperature and manually control where the air is directed and the system will send air heated to the temperature you desired to the place you desired suing the register controls. But this takes the system out of full auto and it will not necessarily get the cabin temperature to the set temperature, especially when the interior and exterior temperatures vary significantly. So in this case 72* heated air through the defroster vents (or other vents) you choose.

3 - You can set it to a particular temperature and manually control how much air is directed out of the system using the fan speed control. But again, this takes the system out of full auto and it will not necessarily get the cabin temperature to the set temperature, especially when the interior and exterior temperatures vary significantly. So in this case, 72* air at the fan speed you choose.

4 - You can set it to a particular temperature and then combine the properties of options 2 & 3 and manually control where and how much air at your desired temperature is distributed by using both the register and fan speed controls. But again, this takes the system out of full auto and it will not necessarily get the cabin temperature to the set temperature, especially when the interior and exterior temperatures vary significantly. So in this case, 72* air from wherever choose, at whatever fan speed you choose.

5 - In certain register settings, you can control whether this heated (or cooled) air is dried of humidity by turning the "A/C" control on or off. This is done by enabling the A/C compressor. Also, the A/C setting is enabled automatically in the "DEFROSTER" position to lower the humidity of the airflow to the windshield, thus drying/defogging the windshield .

6 - With "AUTO" and "A/C" turned off, you can just leave it venting exterior temperature ambient air or heated air on the minimum fan setting or higher, open the windows, shut the whole darn system off, etc. etc..

 

But in the end, the only setting that will entirely control the cabin temperature within system specs is setting it to "AUTO" and leaving it on "AUTO". Once you press another register button to redirect air flow or a fan speed button to increase/decrease air flow, you have taken it out of full automatic mode and hamstrung it's ability to regulate the overall cabin temperature. It will then only blow air heated (or cooled) to your desired temperature to the area you chose, at the air flow you chose. And if your choices are different than the optimum setting that "AUTO' would choose, then the cabin temperature will be adversely affected. While I respect your right to feel otherwise, I don't agree that this is a poor design. It is how Ford (and mot automotive) EATC's have always operated, but has even more flexibility than in the past.

 

Without me going on any longer than this long reply already has: While it is now part of the MyFord/MyFordTouch realm, the EATC system in your Edge operates as all Ford EATC systems do. If you press "AUTO" and do not press any other buttons redirecting the air or changing the fan speed, it will get the cabin temperature to the desired setting (within the system designs margin of error, of course). However, if you redirect the air by manually changing the settings (i.e. hitting the front defrost button) or changing the fan speed, by definition you have now assumed manual control over the system and it will not automatically control the desired temperature and can not operate in full "AUTO" mode. The Owners Manual quotes I have included make this apparent (if perhaps not completely crystal clear).

 

The bottom line? Please do as I asked earlier in this reply. While on a drive of at least 20 minutes, use the EATC system properly as designed. Place it on "AUTO" and leave it alone. If you need to use the front defroster on high to melt ice etc., do so only long enough to melt the ice, then press "AUTO" to return the system to full automatic control (as the Owners Manual clearly states). You will find that the cabin temperature will be automatically controlled and more directly reflect the set temperature. Otherwise, you are continuing to use the system improperly (or at least not as it is designed to be properly used) yet complaining about the results. (BAD ANALOGY WARNING) Until you actually try to use the system as designed, it's like you are trying to use a Phillips head screwdriver to insert a slotted screw, complaining about the poor results, then telling the person who tells you to use the correct tool that they are both called screwdrivers so if it does not work the way I want it to, it is designed poorly. Hey, I warned you a bad analogy was coming.

 

Anyway, try using the system a day or two as it is designed to be used and as I have described. If you still have any complaints with the cabin temperature at that point, then there is likely an issue with your particular vehicle that needs addressing by the Dealership/Ford.

 

And please realize I am not discounting the fact that your EATC may have a glitch/problem and be operating improperly. I am strictly discussing a properly working system.

 

Sorry for the looooong treatise (and repetition), but I am trying to address as much as possible to get the information across. :stats: In doing so, I am trying to answer the questions in as many ways as possible, so that we don't both have to keep repeating ourselves asking/answering the same questions.

 

Let us know how you make out and good luck. :grouphug:

 

PS - I only gave this term paper a very quick proofread, so please excuse any/all grammatical, spelling or typographical errors.

Looking through all the replies it looks like most of you have the MyFord Touch system whereas I have the SEL base climate controlled system. Still, it seems like it works almost the same way. I'm just curious if it's normal for it to turn on every time you start the car if you don't have it in AUTO mode and it was turned off prior to turning the ignition off.

 

The great explanations have helped me understand much better how the system works in my Edge.

Hi GreenDragon. :D With the 2010 and earlier Edge/MKZ, the answer was a definite no. Upon vehicle start-up, the climate control system on 2010 and earlier Edge/MKX models would resume the last setting at vehicle shut-down. So if it was off when you last shut-down, it would be off upon start-up.

 

However, this may have changed with the 2011 models with MyFord and MyFordTouch. The information I have read states that there are user configurable settings to vary what the system does on vehicle start-up, in some cases no matter what it was last set to on vehicle shut-down. This sounds similar to the situation you are describing.

 

Until I research a 2011 Owners Manual or other service literature, I can not verify how this affects the various Edge models with MyFord or MyFordTouch systems, each individual EATC system (there seem to be 3), whether it only has to do with Remote Start systems, etc. etc..

 

Have you read the Climate Control and other user configurable settings sections for your particular EATC system in your Owners Manual?

 

My apologies for not being able to give more accurate information, but until someone with more on-hand knowledge jumps in with a reply, that may be your quickest way to get an answer to your questions.

 

If I can find any useful information, I will post back. Keep us updated if you find any concrete answers.

 

Good luck. :beerchug:

Hi BBF2530,

 

WOW! You rock! As I mentioned before, this is why I love this forum as people genuinely try and help everyone out. I don't think I've ever has someone type so much in any forum to me before.

 

But I have one comment...

 

"3 - "With the Mytouch, I have the ability to have the fan on AUTO, while still manually controlling the vents." - No, you are mistaken..."

 

Then why if I go to full auto and then change my vent, does it still say "AUTO" above my FAN unless I press the fan button as well?

 

Note: Pics went in out of order!

Hi AXCL :D . I still have carpal tunnel from the last reply, so here is a shorter one (EDIT - Well, in retrospect it kept growing and growing! ):

Out of that entire term paper of information explaining the EATC system, that is what you picked out to partially quote to try to make a point? Really Sheldon... I mean AXCL?

AWWW...come on now Sheldon.... "Bazinga" (love that show)! First, by quoting only the first first four words of my reply to #3, you have quite egregiously quoted me out of context. That was very naughty. If you quote my entire answer, (or even just a sentence or two later in the reply, where I clearly stated "..making those changes takes the system out of full automatic mode so it can no longer efficiently regulate the cabin temperature setting", it is quite apparent that my answer addresses the very subject I was attempting to address ((full "AUTO" versus partial "AUTO"). Even your photos show that pressing "Defrost" took your EATC system out of full "AUTO" and placed it in partial "AUTO" where only the fan is still on "AUTO". See how the "AUTO" icon/wording has shifted in photos 1 and 2 from straddling the register and fan speed fields to being located directly over the fan speed field? As your photos show, you are out of full "AUTO" and only the fan speed (and temperature) is still on ":AUTO". Thus partial and not fully effective "AUTO" function. Again, the problem here is you expect full "AUTO" control of the cabin temperature while exercising manual control. That simply is not the way the system is designed. See below for more comprehensive explanations (well anyway, repeats of my previous explanations).

 

While either my replies are a bit confusing or your understanding is a bit off (I will even volunteer to take the hit for unclear explanations if I have to :shades: ), this isn't Theoretical Physics, "Sheldon Cooper" (have I mentioned I love that show). Warm air rises! You can't expect the HVAC system to blow warm air only at the windshield, yet still keep you and your passengers warm. This is especially true the larger the differential between the outside temperature and what you want the inside/cabin temperature to be. So the colder the day, the unhappier you will be with the EATC set to "AUTO" and manually to front defrost (as I have previously stated and your experience shows).

 

Now that we have the quoting out of context thing settled, Second: You have to carefully read both what I stated in my replies and what your Owners Manual states (and I quoted). It is very simple, by hitting the front defroster or any other air redirection button, you have taken it out of full "AUTO" and placed it in partial "AUTO" (fan on auto), as I have stated several times now. Hitting any of the air redirection or fan speed buttons takes it out of "Full Auto" control, leaving the other controls on auto. So while this does leave the EATC in partial "Auto"mode, that obviously leaves the system hamstrung since once you have manually taken the system out of full "AUTO by using the air redirection or fan speed buttons. By doing so, you are hampering it's ability to fully control the cabin temperature by redirecting air (or air volume) to the areas needed.

 

Again, warm air/heat rises and you are essentially manually forcing the EATC system to blow all the warm air up at the windshield, but complaining that you and the rest of the passenger compartment aren't getting warm enough. Yikes, that is not logical, "Sheldon".

 

Simply put, at this point you expect to be able to exercise partial manual control (placing the system in partial automatic mode) by telling it where to send warm air, but for some reason still expect the system to operate in full "AUTO" mode and maintain cabin air temperature automatically. If you would simply read your Owners Manual, you would see that it clearly states that can not be done. You must hit "AUTO" and leave it alone. As I have quoted previously, the Manual states that if you hit "Defroster" or any other air redirection button, you must hit "AUTO" to return to full automatic control. The fact that your system is not working as you like it (while you insist on ignoring the Owners Manual instructions) should give a hint that your ideas on how the system "should' operate are incorrect (again, assuming there is not a glitch that needs addressing by the Service Department).

 

In addition, I notice you completely overlooked this paragraph in my previous reply to you ("Bazinga"! ):

"Anyway, try using the system a day or two as it is designed to be used and as I have described. If you still have any complaints with the cabin temperature at that point, then there is likely an issue with your particular vehicle that needs addressing by the Dealership/Ford.

 

Again, at least try using the system for two or three days as designed, as the Owners Manual tells you to operate it and how I have explained to operate it. If you still have a complaint, then your car may need service. But you can't keep operating it incorrectly and expect it to work as designed. Essentially, you keep ignoring the advice, your Owners Manual and your experiences with your own vehicle etc,, yet telling me this advice, the Owners Manual and the accounts of your personal experiences are incorrect.

 

So use the EATC system as it is designed to be used (if you want and expect full auto functions), then let us know if you still feel the same way

 

"Bazinga" again, right back at ya', Sheldon Cooper!

 

Good luck. :beerchug:

 

PS - AXCL, hope you understand I am taking this all in good fun and just joking back with you (although the information being provided is still correct). :grouphug:

 

PPS - Allen, you are correct,that the MyFord and MyFordTouch EATC systems work slightly differently than 2007-2010 EATC;s. But I took that into account when I researched how the system works in the Owners Manual and other service literature for the replies to AXCL's questions. And in the end, once out of full auto, the results are essentially still the same as previous model years EATC systems.

I am Bazinga - not AXCL ... and though long winded, it sounds like what you are saying is correct... my mind tended to wander since it wasn't me directly effected.

 

But my two cents...

 

It hasn't been above freezing here but two horrible freezing rain filled days since sometime in October and I have my system set to auto 70 and with the exception of getting in at the end of the work day when I forget to start it and I have to turn on the defroster, I have been extremely toasty. I turn on my seat to high because I love me some toasty bums after driving cars without heated seats all of my driving life (may even turn them on in the summer) but my husband and daughter don't have theirs on and often complain about tooo hoottttt mommmmmmmmm!

 

But I too love BBT and at times I really think this might be Sheldon's car.

wow - we agree on something Wilson.

Hi wilson. :D Your head hurts!? I am having so much "fun", I need a three pound aspirin just to dull the headache and wrist pain from all this typing.

 

At least, you can choose not to read this exercise in futility at all. I am trying to help AXCL understand the EATC system, at some time in the hopefully not so distant future (God willing). :shades:

 

Good luck. :beerchug:
