HELLO

DOES ANYONE KNOW HOW MANY RELAYS OR SENSORS CONTROL THE A/C COMPRESSOR. JUST BOUGHT THE CAR, A/C NOT WORKING, FILLED UP THE SYSTEM, NO LEAKS, THE COMPRESSOR WORKS FINE WHEN POWERED DIRECTLY FROM THE BATTERY, BUT WILL NOT COME ON WHEN IN LINE. I ASSUME THAT A RELAY MUST BE DEFECTIVE AND NOT LET POWER THROUGH TO THE COMPRESSOR WHEN IN NORMAL MODE OF OPERATION. IF ANYONE KNOWS WHERE I SHOULD START TROUBLESHOOTING IT WOULD BE APPRECIATED.

THANKS
JERRY

 

the fuel pump relay and a/c relay are located on the base area of the windshield from engine compartment. it's the black box the size of marlboro flip-top. clean those corroded terminals with fine sand paper. smell for any burnt electronic part too.
