Quite a number of problems can cause your AC to fail, but perhaps the most common is low refrigerant. Refrigerant usually leaks, or more accuately seeps, out of the AC system. Over time, you'll need to add more refrigerant. The system detects low levels of refrigerant and shuts off the compressor until you add more.That is NOT the only reason AC systems "stop working".Faulty compressor, clutch, relay, switch, fuse... all of these and more can fail, causing the AC to stop working.
