Oops! I did it to myself. A previous owner had hacked into the over heat/condenser fan wiring harness and I straightened out the mess (I thought). I think I used a regular ground instead of using the A/C pressure switch.

Found out by unplugging the relay I had re-wired. Back to the soldering iron!
