'92 GT, 5.0 all stock. Factory installed a/c with Nippon Denso compressor.
A/C inoperative. Jumpered low pressure switch, clutch does not engage. Have +12v at the BK/Y wire at the clutch. Checked ground (BK at the clutch)-and no ground. Where does it ground to? I followed the A/C clutch harness back as far as I could, and the BK wire disappears into the harness underneath the starter solenoid. At the 2 pin connector, BK/Y remains-but BK from the compressor turns into what appears to be a BK/W wire which , If I back probe the BK wire at the clutch and run a jumper to the negative (-) battery terminal, the clutch will come on. I have a bad ground, but I'm not sure where the other end of the BK wire goes so that I can investigate?
