    My problem is similar but my left side will blow cool air periodically and then will blow hot air. If I turn the system off for a while it will work properly for a while then will go back to hot air. It Does the same in the winter--alternates between cool and warm.

    when the temperature dial is set all the way to hot it blows hot. However, when you change the dial to 75 or 70 degrees it immediately blows cold air.

Removing the fuse for a few minutes and turning the controls on both driver side and passenger side to the highest setting and then turning them down slowly until the system started cooling has worked for me. Thanks for the suggestions---saved me $2500.00 on a useless dealer estimate to fix problem. These dealers are dangerous---they were the ones that caused my problem when they unhooked the battery while replacing my ignition switch.

This is a good forum.

I would try resetting both sides. i.e., Set both sides to hot, then back down to cool. Also check your fuse. I am not sure, but would think, you have a fuse for all these different items. It is time consumming, but look through and find your blown fuse. Hope it helps.

Rear heating problem


Hi Jeff. I had the same problem, along with others on my 03 Denali. Along with not blowing hot air from the rear heating system, I had hot air blowing out of the passenger side and cold air out of the drivers' side vents. My battery would go low and had the same smell. I took my Denali in to the dealer and they found it was a bad Fan Control Module. They replace it and everything worked well after. It cost me $293 for parts and labor. Hope this helps.

Air conditioner blows hot air after 30 seconds on drivers side, on start up. Passenger side works fine. Air blows out correct vents per setting on air conditioning. Replaced blend door actuator on drivers...


I have had this problem. I am not a mechanic...so to correct the issue temporarily, I simply turn off the car and restart. This has worked everytime for me. In extreme cases, I think you can also remove the AC fuse and start the car, which will also reset the computer. I also think that by taking the climate control off the "AUTO" setting has worked in the past.

2004 Yukon. driver side air conditioner not working


you need to change drivers side temp door actuator then disconnect battery for 5 seconds and reconnect after changing the part, turn key on for 60 seconds with touching heater control to allow actuator to program and then it will work.

2005 yukon denali, a/c worked fine until battery died


Get the climate control computer relaced or reprogrammed. There is a good chance that when your vehicle was jump started it fried the climate system.

OMGosh...denali blows out hot air on driver side vents


You can do on of two things to see if it will reset the hvac system. Remove the negative battery cable wait two minutes then reconnect. This may reset the hvac. If not you can turn your switch on, but don't start it. Pull the shift lever down to 1st gear tilt the steering wheel all the way down. Now start pulling toward you with the trim on the dash to remove the trim. When it is removed, you can remove the Hvac controller. Once you remove it disonnect the wires wait two minutes and reinstall. This should get you cooling.

Changed batteries and climate control not working properly


The actuator has gone bad. They can be programed, and reset, but usaly they are bad, and that will only patch the problem for a while.
