Rear heating/AC

[LOUDHOE]

My rear heat/AC is cold in the winter and hot in the summer, i left it on for my entire trip back to college and it never got warm, i know its a seperate unit in the back but i tink:think: its broke, anybody else had this problem

[Chevyrider619]

Common problem...mine just blows cold.

Oh well...

When I bought mine it was only blowing cold. The actuator for the blend door (hot/cold) was stuck on cold. For a quick fix and since I don't need the a/c for awhile I put a screw through the actuator to hold it in the hot position.

where is the actuator located? and was yours blowing cold in both front and rear or only rear. mine worked fine until my battery went dead when i replaced it the front and rear blew hot (it was in the summer) , then i disconnected the battery again and i thought every thing was right until my son rode in the back , so now we just leave the rear turned off

at least your's works. mine doesn't blow any air at all. i have no idea what is wrong. the rear radio/temp control console just says "OFF" when you press anything. the aux controls on the center overhead console don't do anything either. bleh.

hello I'm new to this site. (former Trailvoy member) I'm having the somewhat of the same problem....

when I press the A/C power button in the rear console it lights up and says "OFF" then truns back off. the controls in the front over head do work so I can get A/C back there, but I'm trying to find a fix for the rear controls. Any suggestions would be great.
