My 95' Grand Am has been through alot in the last couple weeks. The first thing I noticed was the ABS light staying on, and in that same day the carh left me sit, dead battery , we thought.We ad the battery checked, decided it was the starter...changed starter. Found that it was the ignition switch... changed the ignition switch. By then of course I needed a new battery. Thought we finally had it licked, driving nicely, ...until I tried to put on the A/C...it WAS working well before all the craziness... now I can hear the A/C when I turn the knobs, but nothing comes out. Oh and did I mention that we just had the alternator replaced this afternoon?
Can anyone tell me what to do about the A/C? I don't know if someone could've knocked a wire loose or something (perhaps while replacing the ignition switch)I don't know what to think at this point.
If you took time to read this rant ...THANKYOU. Any help would be great!
