A/C not working on driver's side

mattison · May 2

Last year I noticed that my A/C was not as cold as it should be, so this year I took it in to get looked at. The repair shop said they evacuated the system and refilled it and it was blowing cold. After picking up the truck, I ran the A/C and it was warm air. That was a week ago. I haven't had a chance to call the shop yet, but today I found out that the passenger zone was blowing cold and the driver zone was blowing warm. Both temp dials were on Lo. What controls the temperature to each side so I can replace it?

there is a temp blend door for each side, sounds like the driver side is not working or is stuck to heat.

in a quiet place, with key on (door closed to keep dinger off) run the passenger side temp control from "LO to High temp and listen under the dash on the pass. side and see if you can hear the blend door moving, if you do then repeat the same thing on the driver side and see if you hear the door moving, if not then that's the issue, try it a few times might "Unstick"
