Rear climate control not working

[vatahoelt]

Been trying to get the rear climate controls to work, but not having much luck. I've tried replacing the rear temp control module and the rear temp blend door actuator. After resetting the rear system with the fuse out, the actuator just goes straight to the hot setting. I can't get it to re-calibrate. Anyone have any ideas before I ask for recommendations for a local shop?

do a search. there are many write ups on fixing. I think it is 'blend' door that controls air flow? I have to fix mine too. You should be able to fix yourself.

I've take mine apart and found the blend door broken. Still stuck on hot till I can fix it.....

I've replaced the actuator, but after doing a reset, it just goes straight to blowing hot. I can't get it to calibrate. Not sure I need a Tech II to clear the codes or not?

Does it ever switch to cold at all? I just removed the actuator and could actually see that the blend door is broken.

Disconnecting the battery should relearn it, just don't touch any HVAC control for about 60 seconds after starting the engine or the relearn wil abort.
