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.

I have a 2004 Silverado Crew Cab, the temperature on the drivers side air vents comes out HOT, all the time, while the passengers side can be controlled by the temperature control lever. If I push the A/C...


I think you will find that the mechanical control which changes the air flow from cold-hot-aircon has come off. I'm not familiar with your particular vehicle but usually the dash lever control is connected to a wire or lever to each air duct. If one of these is not connected then the duct will stay in the position where it was at when the control wire. lever came off. A good place to start.

Driver side hot passenger side cold


You most likely have a bad Temperature control door actuator on the drivers side. When you select a temperature setting with the dash controls these actuators move the air temperature control doors to match your settings and give the controler feedback on what their position is. If an actuator goes bad it loses it's place and will often end up at the full heat position. Sometimes they will work again for a while if you shut off the vehicle for 15 seconds or so and try again as the actuator will reset and be in the right position again until it stops working once more. Hope this helps and good luck!

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

2004 Yukon XL - air conditioner is working fine, then heat comes on on drivers side and air stays on on passenger side


suspect tempreture sensor on drivers side. it seems to send a signal that this side of the car is too cold.

if you have duel setting so driver can control both sides at same time set also to air and see if it jumps to heat on both sides, if so there seems to be an electical problem with the tempreture contoler.

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.
