electrical problem
Radio stopped playing (turns on), side-view mirrors stopped, and windows don't go down from driver's side control. Passenger window WILL go down and up from passenger side. Passenger window WILL go down when radio is turned on!! I AM NOT kidding. I already replaced driver's side window module. And (this might be strictly co-incidental) my first sign of the window problem was when I was sitting in the garage: As I was lowering my window, I hit the remote to activate the Craftsman garage door opener. At that EXACT moment, my window stopped going down (switch still being depressed) and my passenger window went down. I've been wrenching since 1966. I'm the guy that all the relatives, friends, co-workers and neighbors came to to get things figured out and done. All this sounds too weird for me; almost like I need a priest to perform an exorcism! Please, anyone have any kind of problem like this!

Do you have a scan tool where you can see if you can communicate with all the modules ??... I would start there !!
you may have a serial data bus issue...to the left of the BCM are 2 splice packs..remove the bus bar...the one with the 4 wires...also clean that bus bar or “comb” we call it with sand paper...with bus bar removed see if the windows work and radio now works !!...if no good remove the other bus bar...car won’t start but see if those things work...you may have power or ground issues with the drivers door module or another one...there is a connector in the accordion tube where the wiring exits the door.,,check there too !!
