I posted an issue I had with my passenger door handle on my 92 325is. It was sticking and the door would not shut the greatest. I seemed to have fixed it with WD-40 though. On the same day just minutes after I fixed it I tried to roll down the window and just heard clicking. Up and down both click but no movement. Is the window in a jam? Does this happen often. And also do BMW's go from one problem to the next like almost all cars?
