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 its broke, anybody else had this problem

Common problem...mine just blows cold.

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
