I'm troubleshooting AC system. Press AC switch, compressor turns on for 1-2 sec, then shuts down. Electric engine cooling fan DOES NOT turn on. I thought this fan should come on when AC comes on. I'd like to jump the two wires for the AC low pressure switch and check the compressor. Two questions:
1. Where is connector to low pressrue switch
2. Is there a relay which may have gone bad (causing the fan not to come on and therefore the compressor to remain running)?
