rear air not working

Unread post by cpatrick24 » Thu Jul 31, 2014 5:01 pm

I have a 2003 gmc Yukon xl denali and the rear air does not work. I have replaced the blower motor and resistor and fuses. When I try to power up the air from the back seat consul it lights up and just says" off" and goes out. Is there any other things I can try? The front air works fine.

so you have no blower motor and no temperature control? you should use a scanner and check for DTC's for the rear ac.

you can check and verify power and grounds.
