Jake Hintz Posted June 2, 2015 Report Share Posted June 2, 2015 Am having a weird issue with my a/c on my 2011 sel. With the a/c, max air, and the recurculate light on my car will blow hot air on start up about 8 out of 10 times. Not sure if it coincidence or not but I notice when I'm having the issue, my outside temp is indicating a low temperature like 25°F. If the temperature indicator shows the correct temp the air seems to work fine. Like yesterday it was in the high 70s and my air would not work when we left our house, the temp indicator went into the mid 50s after about 15 minutes and the air then worked perfectly. Don't seem normal for the a/c to be linked to the external temp, am I wrong? Maybe the sensor is bad? Because it seems to take a super long time before the indicator gets to the proper temp. On my other vehicle it is fairly close upon startup. With the edge it is way for atleast 10-15 minutes. I have checked all of the a/c settings to make sure I have it set correctly, and I do. It will blow ice cold air when it's working correctly. And sometimes right when I start the vehicle it will blow ice cold. But at those times I don't remember to check the outside temp to see if it's right or not. Anybody else find this odd, or think I'm crazy. I can't remember from last year but I do believe that in the summer the vehicle produced cold air right after starting. Just the sporadicness(<<not sure if that's a word) of it working on startup sometimes and then most of the time not, has me baffled. Seems like an electronic malfunction to me. The r134 I assume is at a good level because once it works it works great for hours and hours nonstop. If ya guys have dealt with this and fixed it or have any suggestion please let me know. I don't want to take it to the dealer and have it work every time and make me look like an idiot. Quote Link to comment Share on other sites More sharing options...
omar302 Posted June 2, 2015 Report Share Posted June 2, 2015 There is a TSB for the same symptoms, the HVAC would require reprogramming. TSB 11-8-7 attached. TSB 11-8-7_Unable to maintain Temp old.pdf 1 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted June 2, 2015 Report Share Posted June 2, 2015 If the 2007 module is anything like the 2007, you may be able to get codes out of it: http://www.fordedgeforum.com/topic/15071-climate-control-problem/?do=findComment&comment=115324 Quote Link to comment Share on other sites More sharing options...
Jake Hintz Posted June 10, 2015 Author Report Share Posted June 10, 2015 While rotating the tires, I unhooked the battery, held the positive and negative wire of the vehicle together for a minute or so, and reconnected when done. Now the outside temperature display reads correctly as soon as I start the vehicle and not 24°like before. And the a/c works properly every time. So I'm not sure if the computer had a glitch in it but ever since then it has been flawless. Quote Link to comment Share on other sites More sharing options...
MJB3 Posted June 10, 2015 Report Share Posted June 10, 2015 Jake, sounds like you came across a great fix. The old, tried and true reboot. Thanks for sharing. Quote Link to comment Share on other sites More sharing options...
Jake Hintz Posted January 3, 2016 Author Report Share Posted January 3, 2016 Went out to start my edge yesterday and I turned the temp to hi and fan all the up. Well it blows full forces for a few seconds and then cuts out. Then restarts full force and continues this cycle indefinitely until I shut the car off. My outside temp displays 20 degrees then goes to the dashes and then back to 20 degrees. The 3 dashes go hand in hand with the blower resetting. Is there some type of controller that is affected by the ambient temp sensor? https://youtu.be/mNFRHWg9rf8 https://youtu.be/qAci-Frbzwo Here are examples of what I'm describing. If you watch my ambient temp on the touch screen, you will see it change when the blower changes. Any ideas here? If this is a simple fix, that would be great. If I have to take it to the dealership, is this something that should be covered under an extended warranty? Thanks for any info. Quote Link to comment Share on other sites More sharing options...
