Power window woes. Not the clips!

[325ic]

Last night when I was rolling up my window, it made a loud popping sound and then the window stopped half way up.

I searched the threads but only found some threads about the arms coming out of the 2 sliders or the sliders breaking.


My plastic sliders are intact and the arms did not unattach from the plastic pieces. The window is perfectly in the track. So now i'm left confused.

My motor turns which moves the large crescent shaped gear arm. This turns up and down but doesn't seem attached to anything. The arms that the sliders are attached to are intact. The only odd thing is that on the arm that goes towards the center has 3 things that look like broken spot welds? I'm not sure. If anyone has any tips or suggestions it would be greatly appreciated.

Sounds like you need a new regulator.

Mine did exactly the same thing. The problem turned out to be that the stop on the motor was poorly adjusted so the window was hitting the top of the door and then the motor tried to push it another quarter of an inch, which stressed the spot welds that held on that arm until one day they finally popped.

I don't own a welder, and no welding shop in town would touch it because they were afraid that if they messed it up. I would want them to buy me a new assembly.

There is very little clearance in there, so you cannot put in bolts with nuts on the back side.

What I did was, I used a half-dozen very short self-tapping screws that I had in a jar in my garage. I think they came out of some old computer hard drives that I dismantled once. I drilled a half-dozen holes in the assembly and put in the screws. When I tested it I saw how the assembly tweeked out of shape because it was trying to push the window up too far, so I adjusted the stop on the motor. That was about 3 years ago and it is still working.

To get the motor assembly out, you have to drill out some rivets that you will replace with short stove bolts with nuts.

The other thing I learned in that exercise is that the arm that attaches to the back of the door that squares up the scissors assembly is surprisingly sensitive. After this repair I had wind noise at the back of the window for a year because the window was not seating properly in the back of its slot. It took only a very small adjustment of that arm in its slotted hole to correct the window fit and get rid of the wind noise.
