Hey Matt, Make sure that your getting the 12 volts when the a/c is switched on from the compressor wire, if so, I know it sounds stupid but check to make sure that the compressor itself is showing zero resistance against the engine block. In otherwords make sure its grounded. I know its all metal on metal and it sounds stupid but I've seen it before. Goodluck!
