Z3 window won't go up?

[shoine 0]

Hi guys,

Title says it all. I could hear the motor running, but it sounded like it got stuck somehow. 

I stripped the door panel, and now can see the motor, the window and everything else but I do not see anything broken. How do I take it from there? I just found one weird thing broken, but seems very rusty and the window has not been going up for less than 12 months (car was left aside for a while).
I added two pics to help me figure it out. Cheers.

Hi Shoine,

If you've got no movement and only the window regulator  motor noise when looking at it with the door card removed.

Then the window regulator needs repair/replaced.

 I'm sure I found a YouTube clip that showed a cog repair.

Give it a google " window regulator repair "

Thanks sweetm3. Currently I have not tried to check the noise/motor with the door card removed, as the battery/airbag is removed.

Is it worth checking? Do I need to plug the airbag back? Cheers

"Is it worth checking"

Only you can answer that

If you turn the ignition on without the airbag connected you will get an "AirBag" light.  To clear the light requires a special scanner, INPA or similar software.
