where does pressure switchthat is located on accumulator get its ground , when ac clutch disengages theres no ground at pressure switch. itake a 12volt test on ground and probe ground at pressure switch and clutch andfans will engage.
The pressure switch gets a ground on the front of right front fender.on the black wire.The other ground on the blue/orange wire comes from the engine control module.Do you have any gages? If so can you please let me know what readings you have on both the high and low side.
