Yeah, mine does that, too (idle jumping 2500 to 1500rpm), but the compressor doesn't run. Even after I put a can of refrigerant in it. The A/C is nice and cold when the car is moving, but the idle performance sucks. It's almost like the car thinks the compressor is running and the idle compensates, but the compressor never engages.
Does anyone know if there's a relay that controls the compressor clutch?
