I'm going to assume that is on both sides of the cab? I'm going to say you have an actuator problem, if it's in fact only blowing cold in the rear, and not in the front. The actuators are prone to problems on the gm product lines. Even more with a weak battery.

2003 yukon xl front a/c not blowing cold air.back working just fine. added r 134 last week ,with low side pressure of 70 psi,high side at 275 psi.what could be the problem


{: ) Try to feel the the a/c accumulator for coldness. It is that metallic can mounted near the firewall, connected along the a/c suction pipe. Actually, 70 psi is still somewhat high. But anyway, if the accumulator is cold to touch, most probably the problem is on the front air distribution. Assuming that your front blower is working, the cold air could have been distributed elsewhere, to the other vents instead of the front vents.
It can be an actuator or an air vent door fault. There are also GM bulletins for this kind of concern like connector, wiring, or calibration issues. Depending on the retrieved codes by a scan tool, it can help narrow down the search and the cause, and eventually speed up the repairs. So goodluck.

The A/C unit is not blowing cold air in the front. The back is blowing cold and we have re-filled the unit. Still is blowing HOT air?


your split manifold located on the firewall that sends and directs the refrigerant from the front and rear depending on your setting on the dash is plugged or the climate control on the dash is not responding and there could be a fuse,relay,broken wire,but there cant be a leak or either side wouldn't cool

Duel zone climate control on passenger side blows hot air when turned down cold. Driver side works fine.


There is a temp door actuator motor that is not working for that side,the dash has to be removed and laid on the front seat to replace the actuator motor,
