I have had this problem with my 04 Avalanche. It happened when I changed the battery. I replaced the climate control @ $475. When the battery went down another time, the same thing happened only in reverse (warm on the other side) I asked around and found that you can remove the dash trim pnl. and take out x2 screws that hold the controller in place, unplug it for 1 or 2 minuets and reattach. this will "reboot" the controller. I had to preform this procedure 2 times but it fixed the issue @ $0 and is simple. Has worked fine since.

Driver side heat blows cool air passenger side blows hot air


Hello. The side that is not operating properly has a bad temp door actuator located up under the dash. I am assuming this vehicle has driver/passenger(dual)climate control heat and cold settings. This is a very common problem on these vehicles. Hope you find this information useful!

Full heat (no control) on drivers side, cooling on passenger side


The HVAC system has an actuator on the passengers side and one on the drivers side that control mode and temperature. The left side actuator on yours has failed and will need replacing.

Thankfully it was the drivers side controller! I found the temp control actuator located under the dash almost on the floor. I removed the four screws that held the cover in place then followed the wires to the actuator. removed the wiring harness then the two screws. replace with new part and heat works again!
