Hi guys I managed to get a lot of the small issues with the mustang sorted. However the a/c clutch gets power with the engine running. No power with just key on. All switches off. It also has a code 67 that says something about the a/c switch. I tested the diode at the short section of harness from the fender well to the compressor and it is an open circuit not a 1 way like it is supposed to be. I'm wondering if that is allowing current to come from the ECM energize it or just a bad switch.
