Hey guys been a while been addicted to 2 wheel riding. So have a 1993 525i and have an issue with the window. It sounds like the motor is trying but doesn't have enough power to move the window kind of like the gear is stuck to call it somehow. So it was stuck a couple times, then just stopped working. Now last night as I was doing the search I tried slamming the door shut tapped all over the door and then when it wouldn't budge I then went to unclip the regulator so I could pull it up manually and as I was messing with the clip I then tried it and it worked. So I'm not sure how to tell if I had a bent regulator and I fixed it with the screw driver or if the gears are bad in the motor (BMW plastic I'm assuming is the culprit). Any easy way to diagnose? Thanks again for any replies.
