No power gets to compressor from main relay/fuse box under hood. Where can I find circuit diagram for 98 Sonoma AC. It is not in Haines. Is there a connecter between relay box and compressor other than the one at the compressor?
The connector on the side of the accumulator (the big silver can) is a pressure switch.
If the system is out of refrigerant, there is low or no pressure, and that
switch disconnects power to the compressor.
