Window Regulator Adjustment Problem
1 Attachment(s)
Ever since I got my 2001 z3 a couple months ago, the driver's side window goes up to high and I've been just manually stopping it where it's supposed to be when fully closed. Over the holiday break I got into it to see what's going on. The regulator adjustment screw is missing it's target! I managed to get my phone in there to capture a picture. Anyone have an idea what's going on or how to fix it? Is the regulator not mounted properly or something?

Looks like the regulator is loose or the window is off the track. You'll have to get inside the door to check it and fix it.
Be sure to heed the side airbag precautions when you do.

Thanks WisM - I did get in there and everything appeared tight and on track. So I replaced the regulator and put new plastic clips in for the rail (the old ones did have a broken corner each). Everything back together and working... except... same problem. The new adjustment screw came with a plastic tip that seemed to catch the edge of the stop... for the first try or 2. Then it "popped" and the window went right on up too high again! (grrrrr...) So I took a trip to the hardware store and found an oversized metal "head" thing that I could screw onto the adjustment screw to make SURE it caught the edge. Same thing... worked for a try or 2, then "pop" and the window went up too far. That's when I figured out that the door panel is actually flexing under the pressure of the window motor! So the stop just gets pushed out of the way!!! I'm now thinking about trying to bolt a plate onto the stop to extend it out under the adjustment screw, but who knows if this'll create new problems. Again, any help would be GREATLY appreciatted!

Well, that explains the slide/rub mark on the stop where the stop screw passed it. I am unsure, but the motor stop/ reverse would be pressure actuated as part of the safety system. It seems like the motor is not stopping as it should. I don't know for sure though.
Perhaps one of the forum electrical experts knows. I could not find clear information on how the motor shut off works in the Bentley manual.

Here is a DIY for replacing the motor in an E36. In step 7 of the installation part toward the end, it mentions teaching the motor the travel limits. Perhaps you could try that. If that does not work, I am going to guess that your motor needs replaced since it sounds like the sensor function is integral to the motor.

Good luck.

Thanks again! That may be the ticket... If I can get some kind of a bracket or catch in there that will stop it where it needs to be, then maybe I can use this "limit set" procedure to keep it from causing the thing to flex.

Here is a different reset procedure I ran across you can try if the other did not work.
