Just went through the same thing with my 89 535. tried a number of different things but this is what fixed it. under the rear seat is a fuse box/relay holder. Under the plastic cover are two boxes that i thought wrer computers. the rear box controls the windows. i pulled it out oand opened it up thinking what the hell, the dam thing is already broke so what can i hurt! inside are about 15 or so relays all on a common board. i had one relay that was stuck in the on position. i removed the small spring on that relay, removed the movable part and cleaned the contacts. that did the trick! now i have windows and a sunroof again! if cleaning the contacts will not work you may have to buy a new relay box...dont know what they cost.
