I have a 2000 Escalade and I am experiencing an intermittent problem that is occuring fairly frequently. While I am underway, the elect. windows, radio and windshield wipers will all become inoperable. All other electrical functions continue to work correctly. If I leave the car turned off for an hour or so, the devies will begin working when I start the car again. Anyone out there with an answer to this problem.

Thanks!

 

Problem may center around bcm, and / or power or gound to it.GM has also had issues with ignition switches dropping 12v feeds. Check for 12v at effected fuses and bcm when condition occurs.Bcm under compartment in center console. You can get to connector, but console has to taken out and apart to replace it.
