Okay I'm having some air conditioner problems and I'm hoping you guys can help. First, AC blows no cold air, so we know that's a problem. But that can be fixed with freon. Biggest problem is that when the AC is on my car idles really oddly. Will go up to 1500, then down to about 500. After a minute or two, car will just die. It has done this while driving and is obviously very annoying. When I try to put freon in, the pressure gauge goes all over the place instead of staying in one spot. I really need help with this because it's really hot around here. Thanks for any help.
