Problem: Cool air blowing from Driver side, warmer air blowing from passenger side.
Completed: Coolant is topped off and has not been low. I pulled the dash to look at the servo's. All 4 servo's appear to work. Recirc moves correctly. The Mode servo moves and directs air to the correct vents. I loosened the passenger and driver side blend servo's enough to allow me to manipulate the levers myself. They are both working fine. If I raise the temperature control, the servo will move all the way up and blow hot air. When the temp is lowered the servo will push the gear lower. Any ideas on what else I could check. I pulled the climate control thermometer (not sure what it is called) under the steering wheel hoping maybe it was dirty, but it looked clean. Cabin filter has been changed also. The freon level and pressures are good. The compressor and clutch are working properly. Line out of the compressor is very cold. Would the room temperature sensor cause this? What about the high pressure switch? Any help would be appreciated

I have the same issue but hasn't been solve yet on 2001. My uncle whose a mechanic stated that it might be because of the passenger side module is bad which is not letting the ac change the temp. And cannot register to give out cold air

I am leaning toward the room temperature sensor. But I am not sure and no one has pointed me in any other direction yet. I have tried to run the diagnostics and I get 11,21 and 24 codes. I do not hear any beeps thought when the codes come on.
