a2zed Posted June 11, 2014 Report Share Posted June 11, 2014 Just had maintenance last day of warranty today. The Service advisor used to be a mechanic and knows everything? I'm using the Auto Climate Control feature [which I used to be able to turn off.. but stays on and cannot be turned off] and have the cabin temp at 24c with outside ambient temp at 16c. The AC comes on and will not turn off. I'm actually asking for a little heat yet get cold air. The guy tells me to turn the AC off. Ok, got that part but where's the Auto feature? The manual - Climate Control Auto will adjust the cabin temp to whatever temp is set by turning the AC on or off as required. Am I missing something? Just new to the forum today, but have browsed topics before. I must say, this is a great place for Edge owners. Thanks for your input. -z 1 Quote Link to comment Share on other sites More sharing options...
akirby Posted June 11, 2014 Report Share Posted June 11, 2014 The A/C compressor has nothing to do with temperature - it should be warm air either way. Could be the blend door stuck or the controller or the temp sensor. Keep on the dealer to fix it or find another dealer. Quote Link to comment Share on other sites More sharing options...
a2zed Posted June 11, 2014 Author Report Share Posted June 11, 2014 Are you referring to the Auto controller? Seem to recall that I could turn the Auto feature off, but now its on all the time. Quote Link to comment Share on other sites More sharing options...
Waldo Posted June 11, 2014 Report Share Posted June 11, 2014 The "Auto" function controls the fan speed, the temperature, the mode selection, the recirc function and the A/C compressor. If you press the "auto" button, it will control all of those things. You can override any one or all of those functions (like changing the fan speed or turning off the A/C) by pressing the buttons. Everything else will continue to function in auto mode. So to turn off the A/C compressor, just push the A/C button. Everything else will still be in auto mode, but the compressor should not come on. If this is not how yours is working, then you have a problem that the dealer needs to address. Quote Link to comment Share on other sites More sharing options...
akirby Posted June 11, 2014 Report Share Posted June 11, 2014 But whether or not the A/C compressor is on or off has nothing to do with the temperature not working correctly. Put it in full auto mode and set it on the normal desired temperature. If it's 16 outside and you have it set on 24 inside and it's not giving you hot air (AFTER THE ENGINE WARMS UP for a few minutes) then you have a blend door or controller or temp sensor problem.

Not necessarily, if there's enough sunload at 16C outside it could still be putting out cool air to maintain 24C inside. It was 16C outside on my drive in this morning and the A/C was running and putting out cool air when I was set at 22C.

akirby Posted June 11, 2014 Report Share Posted June 11, 2014 Great point. Forgot about sunload. Quote Link to comment Share on other sites More sharing options...
a2zed Posted June 12, 2014 Author Report Share Posted June 12, 2014 The tech checked the system again and said no codes were thrown and the system is normal. Once Auto is selected, it cannot be turned off unless an Auto function is manually set, ie. fan speed or vent upper lower etc. In my case at the above temps.. there was no sunload, just UV. I still haven't seen the AC turn off in Auto mode but have had it come on when required. Quote Link to comment Share on other sites More sharing options...
akirby Posted June 12, 2014 Report Share Posted June 12, 2014 But that is the way you take it out of Auto mode - you manually select something. I think that's how it's designed to work. Quote Link to comment Share on other sites More sharing options...
Waldo Posted June 12, 2014 Report Share Posted June 12, 2014 Agree, that's exactly how it's supposed to work. If the light is not on above the A/C button, it might still be on. But if you push the A/C button the light should come on. If you push it again, it should go off, and then the compressor should never come on.

a2zed Posted June 12, 2014 Author Report Share Posted June 12, 2014 Ok.. got it. What I don't understand is that when I turn Auto off with a manual selection, then turn the A/C off - I'm in manual mode. Should stay that way right? Nope. When Climate Control is turned off/on.. Auto and A/C come back on. It wants to stay in Auto mode (not that that's a bad thing). I seem to recall that wasn't the case earlier. I could turn CC off/on without engaging the Auto function. Anyone had this experience? Quote Link to comment Share on other sites More sharing options...
akirby Posted June 12, 2014 Report Share Posted June 12, 2014 That was a bug that might still exist in older vehicles where the A/C could not be turned off that way. It should work but didn't. Do a search - there was at least one or two threads on it a couple of years ago. Quote Link to comment Share on other sites More sharing options...
teknowiz Posted June 13, 2014 Report Share Posted June 13, 2014 Most likely causd by issue related to one of the attached TSBs. My MKX has same issue and was fixed by reporgraming HVAC module previously but after recent AC service is broken again. tsb11-08-07.pdf tsb13-10-13.pdf tsb11-08-10.pdf 1 Quote Link to comment Share on other sites More sharing options...
a2zed Posted June 13, 2014 Author Report Share Posted June 13, 2014 (edited) Don't know if this is normal [my vehicle was May 2011 production] Cycle CC off/on --> Auto - on, AC usually on depending on set temp. Auto will always come on when Climate control is cycled. AC off --> Auto - on, AC should stay off.. at least the AC light will remain off Auto - off, after manual selection --> AC will stay off Turn off/restart the engine --> CC - on, no other lights. AC on --> Auto should stay off The only way to get to a CC one light condition from Auto [and maintain that after engine shutdown] is to turn AC off and then go manual as pointed out by Waldo. Didn't make sense at first Waldo.. but does now because I would always cycle the CC and then wonder why Auto was always coming on. It just does. Can't wait to see the QNX version of MFT.. maybe more logical alternative to Microsoft. Edited June 13, 2014 by a2zed Quote Link to comment Share on other sites More sharing options...
Waldo Posted June 13, 2014 Report Share Posted June 13, 2014 Can't wait to see the QNX version of MFT.. maybe more logical alternative to Microsoft. Actually the climate software is one of the few items that is not part of the Microsoft MFT software bundles. The climate logic is separate software embedded in the EFP (Electronic FInish Panel, the part that has the capacitive buttons) but obviously it does communicate with the MFT software. So can't blame this one on Microsoft nor will doing a QNX update fix it in your vehicle. You should ask the dealer to update the climate software for you.

a2zed Posted August 15, 2014 Author Report Share Posted August 15, 2014 Thanks teknowiz, waldo and akirby. teknowiz.. your tsb 13-1-13 posting may have been superseded by tsb 14-0038, at least here in Canada. The wording is somewhat the same. The issue was that the Auto function would always turn on the AC, no matter what the internal temperature settings were set to. Also, if I turned off the AC in Auto mode, the Auto function would turn itself off. When you have the [Remote Auto Start] in [Vehicle Settings] set to Auto and use the Remote Auto Start feature, this may affect you as it screws with and resets the Climate Control Auto function. Reprograming the HVAC according to tsb 14-0038 fixed the issue! As I posted earlier, I can now for eg. set the internal temp to 24 deg with outside ambient temp at 16 deg with CC in Auto mode without the AC turning on. Anyone with this issue should apply tsb 14-0038, described as Inconsistent Climate Control Function when using Remote Start - built on or before 1/31/2013. Thanks again. Not one service advisor or tech bothered to check for outstanding tsb's and continued telling me on two occasions the CC was working normally because it wasn't throwing any codes. Go figure.. 2 Quote Link to comment Share on other sites More sharing options...
heliguy Posted July 8, 2017 Report Share Posted July 8, 2017 My 2011 edge ac/heat blower cycles on for 5sec off for 2secs. Changed blower resistor and pulled blower and applied 12v direct. All fine. Any thoughts where to go next Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted July 9, 2017 Report Share Posted July 9, 2017 Something similar seen in the Fusion forum. Maybe this will help. http://www.fordfusionforum.com/topic/13214-heater-blower-motor-stops-and-starts/ Quote Link to comment Share on other sites More sharing options...
