2004 chevy tahoe, dual climate control, blowing different temps

Does the vehicle have dual zone climate control, where the driver side and passenger side have different control? Sounds like a blend door issue on the driver side. Why did you replace the passenger side, was it blowing hot too when AC was on?

Sounds like a blend door actuator failure,Might as well replace both sides

My 02 Century has dual temp controls . One for driver for passenger. Make sure you don't have the dual climate enabled and just set for heat on your side and AC on the passengers

this problem is caused in almost all cases by a failed actuator that moves the door insiode the heating/ac duct to change the outlet temperature, it is called the Air Temperature Control Blend Door actuator.

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!

HVAC control head problem or it is the air Temp Control Valve problem. THe control head is the one with the buttons and knobs and the control vavle is located on the HVAC carrier assembly underneath dashboard (two of them one on left and one on right in center). This is a job for someone who has knowledge of HVAC and electrical on a GM vehicle.

I just took mine in for the same thing and they told me my a/c actuator was out.

Touareg passenger side only blowing cold air 2003 3.2 v6 dual climate control

you cant adjust it ,this requires the dealers computer to re set it,or a phyiscal control has packed up like a vacumn pipe has split where it pushes onto the valve that controls the flap in the heater unit.

Temp. actuator stuck on heat , probably . Manual or automatic climate control . Electrically controlled temp actuator , or the door is stuck in heat side.
