04 Tahoe z71

Just sold my 02 rust free Denali XL and I found a pretty good deal on a rust free z71. The rear heat works but the rear AC does not. The front heat and AC work. Where should I start

theres a blend door actuator behind the pass side rear plastic panel. they go bad. had to change mine. the plastic all comes off pretty easy and the actuator is in the wide open to replace. theres vids on yt.

Is it an actuator that switches heat and AC? I didn’t realize it had an actuator for the rear. I was thinking it ran off the one in the front

yeah theres a independent one for the rear, blends hot and cold for the rear passengers comfort lol

Trust these guys, there is a rear actuator. There is on my 05 Z71

If replacing the actuator doesn't work your blend door can break, it's just plastic and gets brittle so keep that in mind.
