2001 pontiac grand prix 3.8 w/170k miles...turn the a/c on and the car clicks (sounds like something is clicking on an off repeatedly) while clicking my rpms start jumping up and down from 300 to 1500 and the a/c stops blowing cold and blows out fire hot air instead of cold
help with my a/c! on 2001 Pontiac Grand Prix
Several things can cause this, low refrigerant (freon) charge, cooling system or fans not working properly ac compressor malfunction ect. Need to see it to fix it!
