A/C has been working great here in FL. Then one day I hear a clicking noise that lasted for 10-15 seconds then quickly goes away. Today - a few weeks later - I hear the noise again so I quickly pull over and pop the hood. The noise sounded like it was coming from the compressor. Again the noise quickly went away, but this time so did my cold air. Any suggestions out there?? When I turn the A/C off and on, I do hear the compressor click - but I don't think it is engaging. Please help!
