Window Winder

[buckman63]

Help please as padded cell awaits

I have been restoring a 2001 S500 for the past 2 years. whole car stripped, engine rebuilt, body resprayed etc etc etc. I'm now attempting to refit the doors, not a difficult task you may add. Only the nearside door needed new window channels which I have fitted and refitted and removed and refitted and still the rear channel hangs about an inch to low with the window wound up. With the window down the glass sits in both channels. Only when the window is half up does the rear channel slow in height compared to the front and by the time the window is up the rear has dropped below the glass by about an inch. I have concluded that either the winding mech is wrong, but looks fine ( nothing was checked before being dismantled ), slipped some teeth or I'm missing something embarrasingly stupid. It's such a simple mech. Are the mech. all the same ??

Any help would be a sanity saver .

Just check I have this right. The winder system that bolts to the door has two arms, that go in to two groves at the bottom of the window. As you wind up one arm dose not go as high as the other?

If That is the case I think 2 posibilitys.

1 Some how you are mounting the system in the wrong position or side (L/R).
2 It has slipped and needs fixing/replacing.

I have so far never had this problem. More problems with the groves rusting away.

Has the other door gone back ok?

I'm also struggling to understand exactly what the issue is.

Are you saying that when the window is fully up, there is a gap between the glass and door frame at the top rear?

Gents many thanks for your replies, issue now sorted. Having stared at this problem all day yesterday I started again this morning and spotted the issue almost straight away. With the winder on the bench and in its fully wound up position the rear arm still had 3 spare teeth to go !!. Raised the supporting strap across the teeth and levered the arm up and over the 3 remaining teeth and now it works fine. Couldn't see it for looking yesterday. Obviously some previous hooligan owner had forced the mech to skip the teeth ??, but as a mini restoration novice I wasn't expecting that.

Thanks for your help.
