I have a 92 Iroc rt. I went thru a long process but now I have functioning ac in my car. The pressures and levels of refrigerant are correct, a shop did it. My problem is with how the car functions the ac, sitting idling, the ac doesn't get very cold, bit as soon as you start driving, it's really cold. Doing some other weird things.
What controls the ac system? ECM, bcm, or the climate control itself?
