I think I have a bad A/C compressor. I put 12v to the number 3 pin on the clip inside the wire harness box by the battery and test the A/C compressor clip where it plugs into the A/C and it got 12v then when I turn the A/C on in the car no volts... I also put 12v to the number 3 pin with the wire clip put into the A/C and the clutch didn't engage. I've been trying to read through post on here but I'm not finding my exact issue I don't think. Is there something at the climate control that would stop the A/C from getting the voltage? Thanks guys
