My car's air conditioner was not very cold. I got it serviced. Two days later car over heated, air only worked when car was moving, stopped when car stopped. I put heat on low and car cooled down right away. I had my thermostate and compressor checked , both are good. The fans work with the heater but not with airconditioner.

Hi DONBIZ,

The fans are controlled by the PCM when AC is operated so you neeed to check the PCM B6 wire for continuity to the fan relays. If continuity is present and grounding it operates the fans the PCM is faulty.
