electrical problems on 2008 Cadillac Escalade

The audio system quit until i turned off the igition for 30 minutes. The rear window goes down by itself. The electic running boards quit misteriously but start up after I turn off the igition. The doors will not open with the remote or door lock buttons. They start up again after a while. The dealer told me to bring my vehicle in when these problems happen. They do not seem to be inclined to check my electrical system.

I would find another Dealer because this is clearly an electrical problem or find a good Diagnostic shop. Most if not all of these functions are controlled by the Body Control Module which is the Computer that manages the Body Systems.
