akirby Posted January 2, 2018 Report Share Posted January 2, 2018 Maybe the controller is just fubar’d. Try disconnecting the battery cable for a few minutes just to reset everything. Did you by chance have it set on Max Defrost? Some have that function and some don’t. 1 Quote Link to comment Share on other sites More sharing options...
boiler662 Posted January 5, 2018 Report Share Posted January 5, 2018 I am pretty sure the 2010 does not have max defrost unless that is the standalone defrost button. Now that temps have returned to normal for South Texas everything works as it should that leads me to believe it is a software issue and the system freaks out once the temps drop below freezing. Does anyone have the TSB # to update the HVAC system? Also,I am guessing it is not normal to have the air flow directed to the floor (not the floor and defrost setting) and air comes out of the defroster vents in the doors?

boiler662 Posted January 6, 2018 Report Share Posted January 6, 2018 After further investigation I am thinking the recirculation door is stuck in the recirculation mode, I hear no change in air flow when pressing the button which would also explain why the defrost setting was not working properly that still does not explain why the heat sky rocketed when the Temps were so cold. If the door is stuck is it behind the glove box and which motor controls it? Has anyone ever had to fix it before? Thanks Andy Quote Link to comment Share on other sites More sharing options...
boiler662 Posted January 6, 2018 Report Share Posted January 6, 2018 (edited) Got it figured out thanks akirby it was due to recirc being on. It turns out the piece of the blend door that connects to the motor broke. If the door is closed it will open however if the door is open it will not close. From what I can find the door is part of the entire housing so it is off to the junk yard to find a door.

JP-WI Posted January 26, 2018 Report Share Posted January 26, 2018 I finally found out how to solve this issue. When I start the car, I press Max AC, then switch to defrost/floor heat. The moisture is pulled out of the car and the windows are clear. If I forget, I see the fog start, press max ac, go back to defrost and the windows immediately clear. Clearly in my vehicle, the AC compressor doesnt run in defrost with AC light on, but if I blow it into my face on Max AC first, the compressor continues to run.

enigma-2 Posted January 27, 2018 Report Share Posted January 27, 2018 Correct me if I'm wrong, but doesn't engaging the Max AC just close the recirculation door? The AC compressor runs if either the setting is set to defrost or Max AC. Setting it to Max AC just allows the system to run colder, running on defrost runs both AC and heat to the windshield; just takes a little longer is all. Are you saying that your defroster doesn't run the compressor? (I believe to doesn't run at all below a certain temperature). Quote Link to comment Share on other sites More sharing options...
Barbied1974 Posted February 21, 2018 Report Share Posted February 21, 2018 I am having the same issue with my 2014 edge (new to me) 35000 miles. Could you please PM me I am new to the forum and cannot pm you. I am taking the edge to Londonderry NH dealer Quote Link to comment Share on other sites More sharing options...
Alex18 Posted November 5, 2018 Report Share Posted November 5, 2018 So lets pretend someone who knows nothing about cars is having this issue in a 2014 edge. Lets say that for a pretty long time they thought it was just a user error thing and that not until a boyfriend drove the car did they realize it was a mechanical thing. I live in an area with lots of humidity and changing weather and foggy windows are an issue both inside and outside the vehicle. Please pretend Im a clueless girl and tell me how to fix this. Driving can already be stressful without faulty parts being a component too. Thanks Quote Link to comment Share on other sites More sharing options...

Driving can already be stressful without faulty parts being a component too. Thanks I would suggest that you should pretend to take your Edge to a dealer to fix it. From pretending to read the posts in this thread, it seems the most likely issue is that the HVAC module needs to be re-programmed as per TSB-14-0062 posted here which probably only a dealer is able to do. 2 Quote Link to comment Share on other sites More sharing options...
Linda27 Posted February 2, 2022 Report Share Posted February 2, 2022 I have a 2014 Ford Edge and the defrost system is terrible. I have contacted Ford and have not had any luck. I had my three granddaughters in it to go look at Christmas lights and we couldn’t even see them. Besides that is was dangerous because I couldn’t even see. I had my oldest granddaughter scraping the windows while I was driving. I eventually had to pull over. I have tried all different settings in all different combinations and nothing works. Any ideas? I don’t feel I can drive my car in the winter. Here is a link to some video and pictures. https://photos.app.goo.gl/PReGDmTBduWJi3nZ6 Quote Link to comment Share on other sites More sharing options...

Also it appears you have the climate control on auto….. why not use the defrost feature? Edited February 3, 2022 by SC_ST Quote Link to comment Share on other sites More sharing options...

Linda27 Posted February 3, 2022 Report Share Posted February 3, 2022 Hi, no there was not a lot of condensation in the car. I have tried Auto as suggested by Ford, I have tried just defrost, I have tried it all. It happens with 1 person in the car and with 5 people in the car. It happened as recently as last night with just me in the car going a distance of about 5 miles. It is terrible when it happens and completely unsafe.

ebank Posted February 3, 2022 Report Share Posted February 3, 2022 Hi Linda, What is the temperature like inside and outside the car? Does the heat keep up? It seems to me you are either not getting enough heat or enough air flow thru the defrost vents. Has the cabin air filter been changed recently? Can you feel the air flow change from vents to defrost to heat when you adjust between defrost and auto? Is the airflow strong out of the various vents? Possibly the actuator that controls where the air flows is not working properly? 1 Quote Link to comment Share on other sites More sharing options...
jmacken37 Posted February 12, 2022 Report Share Posted February 12, 2022 I too am having this problem with fogging of the interior windows in our 2014 Ford Edge with the touch screen and dual heat system. Of note, this vehicle has a salvage title due to flood damage. I’ve replaced the main blower (on passenger side by glove box which was making a strange noise) and cabin filter without improvement. I’m guessing the recirculating door is stuck? It is unsafe. Has anyone found a fix? Quote Link to comment Share on other sites More sharing options...
Linda27 Posted January 9, 2023 Report Share Posted January 9, 2023 Anyone having issues with their 2014 Ford Edge defrost system should reach out to the NHTSA and file a report. Maybe we can get a recall issued on the safety matter. Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted January 10, 2023 Report Share Posted January 10, 2023 I could be mistaken, but I don't believe that this is a safety issue. In fact, I don't believe that even a heater is required by the Federal Standards. You can't start a recall over a defective convience item.
