Lumina Air Condtioning Not Working
My 92 Lumina car with a 3.1. the air is not working. Can you help?
It was working and then just stopped. I have installed a new pressure switch ,new compresser, changed the controll panel in the dash. And still not working. it has been updated to r134.
I'm about ready to pull my hair out. Checked the fuses in the fuse panel. If you know something else please let me know.

Your blend door might not be opening allowing the heat off the heater core to enter the system, but first, does your compressor kick on when you select the a/c?

Is the system fully charged? If overcharged, it will not work either. Did you have it checked for leaks?

Check under the where the relay goes. I have had a few Grand Prix's that had corroded terminals for some of the relays and fuses. Make sure there is no corrosion, and that you have continuity from there, to the pressure switch. Try jumping the pressure switch connector also, see what happens.
