Question about 2003 Hummer H2

1 Answer

Climate control panel

My driver side blows hot air. I can adjust the temp gauge but still blows hot. Passenger is fully adjustable and works great. Only the driver side refuses to allow temperature setting. I disconnected the battery to reset the computer and got the A/C to work for a minute but then it went straight to hot air again. Also It seems from time to time the driver side blower is not as strong as passenger side when the original problem is in affect. Is it possible this problem is fixed by replacing the climate control module/ Or is there something more?

I have a 2002 Envoy the drivers side air vent blows hot air and passenger side blows cold air not matter what the temp is set on


It's an ongoing problem with Envoy. I had the same problem on the drivers side not getting cold air. It cost me $600. They said it was a door inside the dash that diverts the cold air and the hot air depending on what you want. Worked good for a year, and now the passenger side gets cold air and not hot. Another $600 going out the door.
The repair shop said that sometimes they can adjust it, but most of the time they have to replace it. Good Luck

1999 cadillac deville d'elegance heater problem


i've been down here too myself, and discovered that the temp control motor, located in the bottom of the glove box, which you can access by clearing all your stuff in in and opening a small door.
you can adjust it manually, and see if it changes, if yes, the switch can be defective, as well as the motor, the switch is the most likely problem.
but adjust it manually first.
