Default Climate control freaking out...

I have a 2004 tahoe with the separate climate controls and the drivers side from time to time is blowing hot air while the passenger side is blowing cold like it should and the only way to get it corrected (that I've found) is to shut off the engine and then restart and it'll usually fix itself. Can someone tell me what I need to do to fix this problem????

Well I dont understand what is exactly wrong,what your trying to say is that sometimes you cant get both sides at the same temp,one side blows hot and the other cold until you do a restart then its back to normal,is this correct?

Im not 100 percent sure ,but it seems that something is wrong with the control module,where you control your heat and ac from that sometimes isnt sending a signal to mix the temp properly.That whole part should just unplug from the the back,unplug the old and plug in the new,its not like years ago when there was all sorts of vaccum lines behind it.If you can get one that might be your easiest thing to try first.

Have you heard anything from anyone about this? I am having the EXACT same problem. I have an 04 z71 and have noticed blowing hot air on the driver's side even when I have the controls set to 60. It doesn't last forever and it seems like after I have driven it on the highway for a minute or sometimes during heavy accelerating, it will switch back to cold. Has anyone else dealt with this and know the cause? At least now I know I'm not the only one.

Not really but if I turn the car off and then wait a minute and restart it then it resets and runs right but I haven't gotten any info as to why it's doing it or how to fix it.......

I ended up reading a couple other forums last night and some people suggested that while the truck is running, turn off the climate control and everything else off inside. Disconnect the battery for 15 minutes and this should allow the computer to re-set itself. Turn the truck back on and let it run for a couple minutes. Then re-start it again and it may take care of it if it is a computer issue. It was best described as turning your home computer off by by unplugging it instead of going through the shut down procedure...sometimes you get gremlins if it isn't done the right way. Apparently a lot of people had the same issue when changing out a battery and didn't leave it the battery disconnected long enough for the computer to properly re-set itself. I plan on trying it when I get home from work.

Although I haven't changed the battery or anything it's worth a shot I guess...Thanks!
