My tahoe currently has several issues. All the windows are stuck down except rear passenger window which works fine, Rear wiper does not work, home link system stopped working, at night driving if you open the visor and flip open the cover for the mirror the two lights do not come on however this action causes the instument panel lights to go off, as well as trying to turn on the overhead lights. All fuses for these items are good, just bought new circuit breakers for the box to the left of the brake pedal. Was told this could possibly be the Body Control Module, any ideas. Thanks

Welcome to the forum. Has any wiring changes been made e.g. radio or nav unit?

This sure smells like a BCM issue. Especially if one window works. I've had some wierd electrical issues with mine. Possessed wipers that would start wiping at random times, press the heated washer fluid button, and the set the cruise control; stuff like that. A reflash of the BCM, and they vanished. I'd go there first.

if your answer to sharks question is no to any electrical mods I second hardin's re-flash idea. you could always try disconnecting the battery for a few min and see if any of it clears up...

Thanks for the help no changes of any kind have it in the dealer today to hopefully just reprogram the BCM
