Depends whats happening or not happening, does the fan still blow air, but it's hot? No fan? If air is blowing but hot, the a/c may just need a recharge, or a fan belt may have boken that drives the a/c compressor. There is a low and high pressure switch, one of each, and if pressure is too low, the compressor wont start.
