W900 passenger window - crooked?

well sounds like you need to take the door panel off and watch how it moves when you roll it down. you may need to go buy a new crank assembly for it or the tracks may be out of alignment. but you wont know till you get it apart and see whats happening.

 

One of my W900s had the cradle (?) at the bottom of the glass rust away on one side, the other side was ok; so when you would crank the window down, the good side would do as it should, the rusted side would hang up due to the drag of the gaskets in door. It did eventually pull the good side out of the cradle, and wouldn't follow the crank down. Easy/cheap fix, IIRC .
(If that is the problem, be sure to get the rubber tape that cushions/holds it in the cradle; also examine the related gaskets, and replace all rubber if worn,...... cheap, and you won't regret it.

Big help if you put a LITTLE grease on the moving parts, but if you get too carried away, you may be having a blurry view out that window for a while. (Don't ask how I know that!)

 

Been a couple of years since I had one apart, but IIRC that piece you are referring to has to come off the door. Wish I could remember for sure. I remember blocking the window in up position...... Darnit, this was in 2002, and I'm 56 yo. so you know the rest of the story. If you work like me, quick as you can, put your hand between gear part of window crank, and metal brace, so when that last screw comes out, you'll have the "crushed hand" part taken care of.

 

no no no...that wont happen. ive had mine apart and that wont happen. another problem you could have is... at the bottom of the center track where the lift mechanism is it could be broken away from the door frame. thats what happened with mine as to why i had to replace it. just go ahead and remove the last screw and youll be just fine...

 

Slap it back on there and hit it with a MIG gun. And probably the top one too.
