Dodgy Windows

[Ronanom]

The electric windows get caught, stop and go back down every time I try to close them...
Means I gotta close them bit by bit.
Do I need a new window motor or anything?

Got this from the link below it. Found it when I was looking for my door striker problem. Some people try changing the switch first but... I don't think that works... I've seen another write-up somewhere else as well but I can't seem to find it.

Anyhow check the link at the bottom. If you go through it thoroughly there are a number of possible solutions.

"famous window problem:
many people have window problems with e36 when their windows roll up or down by half an inch at one time.
the window motor has motion sensor inside which takes info from magnetic ring that is on motor shaft. for some reason this ring dislocates and sensor gets no info so motor drive circuit thinks its stuck.
all you have to do is to open motor and relocate this ring. on sedan it can be done without taking window mechanism apart ( and drill rivets) on coupe you have to take mechanism on table.
magnet ring is marked red and red arrow points toward its place where its have to be"

Thanks,
Will check it out

sounds very involved.
window positioning sensors?
do they allow your windows to open a little when closing your doors and then close window fully upon closed door position???
yeah silly me i just read the posts and that should be the case

On my passenger window the automatic roll up will often stop and roll down an inch or so but if I manually hold the window switch in the up position it works correctly. Do you think this is the magnetic ring problem or something else?

I found this video of the problem I'm having. It was posted on another forum but the thread seemed to be dead.
Anyone know the fix for this?
