Fan works on all speeds, A/C button when depressed lights up but no A/C.  Blows warm air.  My mechanic checked the refrigerant pressure and there is no issue there.  He checked power at compressor and zero volts.  So no power at compressor.
So it must be a fuse or sensor in line (prior to compressor) that has failed and is stopping 12 volts from getting to compressor.

Anyone have a wiring diagram and basic troubleshooting steps?
