I wish I would have bought the service manuals for it as the owner's manual doesn't show much. I can't see where there is any connection between the three things that don't work.

I wanted to update you guys on my problem. I was on the right track with my problem, it was contacts alright, but not where I ever dreamed it would be. It was the ignition switch! $320.00 worth with parts and labor.
It seems the GM engineers put the load bearing contacts for some of the circuits in the ignition switch instead of using plugin relays (which would be easy to change) and just using the switch to feed the relay coils. But who am I to tell the brains in Detroit anything.
