The ground wire has to have a short in it some where int he wire harness. You have positive power on both sides of the plug at the compressor because the voltage is flowing through the winding in the clutch field coil and it has no ground to activate the electro magnet to pull the clutch in. It is safe to just run the ground from the engine block to the black wire at the compressor plug,.

I can just run a wire from the compressor to the ground and it will function properly? Won’t mess up any sensors or anything
Ford Mechanic: kalamykid, Shop Owner/ Tech replied 24 days ago

That is correct. The ac compressor relay will cut the power if there is a problem or you turn the ac off.

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.
