I have done a search of previous threads but havent quite managed to find the answer: My drivers window has stuck on my legacy wagon. When I push the switch I can hear the wiper motor winding, and the mechanism also makes a loud clicking noise. The window doesnt move though. The window is also out of position so that it is angled too far inwards. I have taken the door panel off but was not able too see much of the mechanism so I cannot work out what is wrong. I think that some mechanical part (rather than electrical) is either broken or out of position. Does anyone have an idea what or where this could be?
