Electric Window broken

[StuM]

Hey all,

The passenger side window on our 98 Arosa has always been poor - made crunching noises and you could hear the motor turning for a few seconds before it engaged and the window moved.

We have stopped using it as I feared it failing when open.. until today, when my wife wound it down a little (10mm). And... it now won't go back up. If you press to lower it, it'll go down to about 2/3 up, then stop. At this point, it is possible to grab it and pull the glass up, but once released it drops down. If you grab the glass to hold it up, then press the 'up' button... the glass is pulled down until it engages, then goes up to about an inch open and stops.

I removed the door card for a look - but it is just a metal sheet behind with a few holes - how on earth do I get access to the motor and mechanism etc?

Many thanks for any help you can offer.

Cheers,
Stu

Found a very handy guide on ClubLupo showing how to take the motor and regulator out. Will post up how it goes in case it is any use to people in future.

Cheers,

In case anyone has a similar problem...

The guide in this thread to removing the mechanism is spot on:

I took mine out and it was very sorry for it's self. One of the feed wheels had the cable sleeving jammed in it. The main problem was the spool that the cable winds around - the cable was all twisted and had chewed up the wheel. Cleaned it all up as best I could and reinstalled, it worked enough to get the window back up, but will need a new regulator.

The crunching noise I heard was the metal cables chewing up the plastic spool!

Worth noting that this is a ridiculously over-complicated design with, from what I can see, multiple weak points. Apparently, the failure rate on these mechanisms is 45%, which from a quality assurance viewpoint is terrible.
