So that's it - right? Working AC - BUT NOOOOO!
The compressor would not come on when the button was pushed. I thought I had it all wired up, but attempt after attempt proved not. I finally jumped the compressor and traced the wire from the jumper back to the "bundle-o-wires" that I did not strip from the harness - BINGO! The location circled in the diagram was the culprit. I assumed it was spliced in the harness, but apparently, it was spliced in a connector on the F-Body.
After splicing that one connection, the AC and the fans work as designed when the AC is engaged - Ice Cold Air at last!!
Heat Management
I have been suffering with uncomfortable heat on the floor when I take the car for long(er) rides. The floor around the pedals has to be over 100*F. So I added some HP Sticky mat 1/8" under the car, above the cats and added some header wrap to the pipes just under that section of the floor. So far, so good - while I haven't driven the car that far, I have had it to 200* sitting, running whilst working on the AC - and the floor stayed relatively cool. Fingers crossed - time will tell...
