When I first bought the car, the previous owner did in fact replace the compressor. Everything else looks OK, from what I can SEE. I could have bought a bogus gauge, but, the last time(s) I checked, it read "full". What could be causing my A/C to not work? Could it be a simple relay(s)? BTW, my blower only works on #4 speed AND, when I press on the A/C button, the green light doesn't come on. However, if I put the defrost on, the green light comes on...? Weird. Anyways, I recently moved down here to SC and it's in the triple digits almost every single day. ANY help would be greatly appreciated!!! I'm not an ASE mechanic, however, I do know how to work on cars. Thanks!
