04 Yukon interior temp control.

[kybob]

Dual temp control. When turning temp up it responds pretty well on both sides, but doesn’t want to go from heat to cool on passenger side.
Air flow responds from floor to dash and windshield well. Temperature not cooperating.
Not sure where the control valve is.
Thanks in advance.

actuators take a dump. mine are doing pretty much the same thing. thats another task i need to get on. looks like the driver side one is in front of the console, so the seats might need to come out. but thats a good time to do some easy carpet cleaning. pass side is inside the dash, your cutting ac ducks and foil duct taping them back together and removing the dash cover pretty much. ive seen a vid of that job. its not horrible really. it mostly just snaps apart. even the oh sh-it bar is super easy to get off once you see how to do it. each side is a spring clip you push and it slides out the dash.
