Air conditioning troubleshooting 1996 STS
 

Thanks for your time and advise. My air is cold, but blowing cold only on the driver's side of the system. The passenger's side is blowing warm air. The control valves seem to direct the air ok. Air is blowing from all the vents. It appears to be a temperature thing. The system has dual controls....one separate for the passenger. Any help would be appreciated. Thanks in advance.

hey friend, i have the exact problem, but driver's side is warm. did you ever find out what was causing this problem?
