w140 driver's window
 

My w140 driver's window won't go up fully unless I puush it up. Make a rat tat sound.
I heard it might be the rivet that breaks. what do you think?

I'm not familiar enough with W140s to know their window regulator setup, but if it uses the scissor style lift in the front like the W126, I just went through this yesterday afternoon in my 560. Window regulator was deformed, apparently had been jammed at some point in the past.

ok, did plenty w126's. saw a video, they revit from factory.So drill them out
