power window mechanism

My 1997 z3 power windows seized up,so I now have the door panel off and can see that someone has worked on the whole folding mechanism and has welded parts together .When the window is lowered it is binding and I can see were it is causing the metal to fatigue and is now cracking in another spot.I can weld it,but first have to get the mechanism out and see just what is making it bind.So does anyone know if or were there are step by step instructions on how to go about getting it all out.Any help appreciated. Thanks

This same thing happened to me. I attempted to weld it but because I'm an awful welder, I fixed nothing. I'm just not messing with it for now. I wouldn't recommend leaving it like that but I did just through the winter. On mine the only thing I really fixed was there was an alignment bolt on the botton of the door to make sure the window goes up and down straight, mine was gone. I think this is. what puts extra pressure on that welded bracket. Ill be subscribing because I also need to know how to do this. Sorry I'm not of any help. Good luck!

Hi thanks for the support.I got it all apart now except I just can't figure out how to unplug the wire connection on the bottom part of the motor.I can't see anyway that it comes apart,tried squeezing ,pulling,prying,wiggling,yanking,swearing and sticking my tung over to the other side of my mouth and I'm stuck here,anyone ,any ideas or know how.Can't find anything on the forum that would say how it comes off.

Das Stig ,i'll let you know what I and how I did it after it's fixed.

yea! I got it unplugged.There is a little clip on the back side of the plug,that you can't see,but playing with it I heard it click when I squeezed and then it came apart.

Good job. perhaps it's binding on one of the window sliders. They are known to disintegrate over time.

Nice job! Mine is a little different becuase the bracket that broke on mine is the one that is welded to the crash support beam. The top of it just snapped off. Weird right? But there is a spacer in between the bracket and the peice of yours that broke. I tried to weld that spacer back on and when i was testing the window, I heard all my shotty welds cracking and falliong apart. I never took it all out of the door but in order to fix it i know i will. Thanks for the help!

Hi just finished up and put it all back together.and it works great now.I think you will have to take the whole mechanism out it wasn't to bad just time consuming.I followed the directions here for some then it was trial and error,not to many errors.
http://www.bimmerfest.com/forums/sho...5&postcount=58

I welded that spacer back in there,kind of a flimsy way to do it on BMW's part,bound to fail..Then I welded up the crack in the other part and it seems to work good now.The hardest part was getting the window glass back in and found it easier to put the side little triangle window in after the main one was in.
Now I have to do the other side ,don't know if it is the same problem or not.
Good luck and hope you get yours fixed soon.
