Question about 2005 GMC Yukon Denali
I just replaced my battery and when I started it, my a/c stopped working properly. It blows hot air when it's supposed to be cold and switches sides. In other words, it can be blowing cold on the right side and hot on the left, even with the thermostat is turned down on both to 60. Then when I re-start the car, it will swith sides and blow cold on left and hot on right. It's seems to be some kind of electrical problem with the temperature control. Any ideas?
My wife had same problem in 2005 yukon. Turn both temperture controls on dash all the way as warm as they will go, Wait about 1 or 2 mins and turn back to coolest setting. Cleared our problem right up. Do this with car running and air on.

I removed the battery terminal and waited for couple of minutes and put it back. But didi not start the car for half an hour. After that it is OK. Although I could not understand the reason but it worked fine..
