2004 Tahoe, front A/C hot - rear A/C cold

Getting very hot air out of my front vents, cold air out of the back vents. The front also will only blow on the highest setting, rear is fine???

I do not have climate control in my vehicle, thought I'd throw that in too.

Probably a bad blend door motor .Only runs on high would be the front blower motor resistor.stick your head under the dash. and switch it back & forth from hot to cold see whats moving if nothing get a blend door motor.

Okay, didn't notice this at first but in addition to the above it is only the drivers side that's hot, passenger blows cold. Still think it's the blender door motor?

do you have dual front controls? If you do there would be two separate blend doors.

First thing make sure it is not low on R-134a.
Post back low and high side readings at idle and at 2K with compressor running?
Auto AC controls set codes in body computer is you have a problem.
