I also have a 2000 boneville and over the winter i discovered that those same three windows/locks/courtesy lamps doesnt work , I have went through all the fuses which are fine , I will call the dealership and check on the BCM. I also have the wet floor problem . but no sun roof , can anyone tell me what the problem might be for that issue , I read that it may be the connector under the pass seat , i see a connector above the carpet, could that be it or is it located under the carpet

Check the grounding connections under the carpet on each side of the car, driver and passenger remove the door moulding lift the carpet and the wire harness on each side has a ground on the passenger side its for the fuel pump, windows and the drivers is windows power seats and who knows what else. good luck by the way check the windshield its probably were the water is coming from. :rofl:

Another possibility is inside your door skin there is a clear piece like plastic and is sealed with a butyl sealant ( black caulking) it may have come away from the door and not sealing.Pour water around window / door area while open and see if water comes out bottom.If you notice floor pretty wet it is probably soaked as there is a thick padding under carpet and there has to be alot of water to soak thru.I had to remove carpet to dry.

Has any figured this problem out yet i have a 2000 bonneville SSEI driver door works fine pass no window or lock and back doors also do not work i have pulled passanger side seat and checked that is no it anything else that can be done
