Got it back from the dealership.

Turned out to be a bad wire from the low pressure switch, it was reading low signal on their tester and traced a broken connection somewhere In the middle of the wire. All is well now.

Ended up testing a different high pressure a/c switch and hvac control module, not difference.

A different HVAC control module must be programmed to your VIN, they are not plug and play.

It did plug-in-play though all the functions worked, besides the a/c issue.
