That's what I suspected, thats how i found out the pin to check on the harness. Guess I need to find someone local to me that has SDD!

Found out it was the fuse for the AIr Con (Fuse in the foot well on passenger side) had blown!
Connected to SDD and HVAC had red X, showing no connection!

Fortunately, it's a cheap and easy fix ... but now you have to determine what caused that fuse to blow. Or maybe not, and just keep some spare fuses available for when it blows again. And again.

The engine was out a few times, and the battery was replaced, jump started, etc.. since i found the fuse and replaced it, it has been fine! *touches wood*
