I got a reply back from Metra based off the glitched I experienced, they suspect the heater control buttons part, and not the onstar/steering wheel box, and gave me a list of items to verify and reply after work tonight.
Let's hope it's easy as just a flash of the heater controller with different firmware and recover. They also suspect the pink wire between the 44 pin connector and the heater controller as loose. Those guys respond fast!
If you see it, get it, for tomorrow it may be gone!
