Are you getting a trouble code?

not sure if you have rear ac or not but check to see if the rear blows cold and the front hot. most likely it is a mode actuator. have the vehical running and switch the hot cold knob from all the way cold to all the way hot and listen for a change in air movement noise.
(if your not sure what im talking about try it in a known good vehicle first). if your not then you have one of 3 problems, bad control head, bad actuator, or the door has spun past its stops.

Actually I just make sure that I've got the right charge. I think its 3+ lbs because I've got a rear A/C. It says on the hood anyway how much you can charge.
I removed everything evacuate it (Vacuum Pump) and charge with the right amount of 134A. There you go it runs well.
