#49 of 109 my SUV AC is on even after i turned the ignition off. by motery Dec 26, 2007 (12:26 am)
Hey guys!! I have a GMC Yukon XL ’02 and it was fine with me until today, I drove to work (it’s about 20 minute drive) and after I park it I turned it off, then suddenly the AC turned on as if it on Auto, I tried ever thing to shut it down I remove the large gray fuse and small 10amp fuse under the hood and the AC still works I turned the SUV on and I couldn’t even control the AC it seemed it has a mind of it's own.  finally I unplugged the battery and guess what … it works the damn thing went back to normal. my question is what the hell is wrong with my SUV… !!????

Replying to: motery (Dec 26, 2007 12:26 am) Are you sure it was the air conditioning that was running or was it just the air conditioning fan? The fan will run off the battery/alternator which suggests that your fan switch is faulty. The compressor does not run off the battery.   tidester, host SUVs and Smart Shopper Replies to this message: motery (Dec 26, 2007 1:58 am)

#52 of 109 2004 Yukon Rear Climate Control by bbebensee Jan 17, 2008 (3:14 pm)
All of the rear air vents push out cold air where as the front control works just as it is suppose to. Is it a matter of resetting the computer or is it mechanical. The dealer wants $900.00 to possibly fix the problem? Replies to this message: obyone (Jan 28, 2008 12:33 am) cheapengineer (Mar 01, 2008 8:12 am) tjustus (May 11, 2008 2:07 pm)

Replying to: bbebensee (Jan 17, 2008 3:14 pm) You could disconnect your battery for 15 minutes to see if it resets. After I had replaced the rear evaporator core, the system needed to be reset for the rear controls to work correctly.
