Hey Guys,

Can't seem to figure this one out.

I recently purchased an 87 300td and have been going heavy on repair work. One such item is the non functioning front left window. I've replaced/ rebuilt plenty of rear regulators before but this is the first front I've ever had to do.

I pulled the existing regulator and motor out and it works fine. The car had been sitting awhile so I figured it seized up in its track. I then cleaned, degreased, and re-greased everything and reinstalled. Works fine. Great.

Then when I run it all the way to the open position, and release the switch after the window has come to stop, and try to close. It's bound up and wont move.

I can unbind it by taking a flathead and prying on the gears while the window switch is pressed to close.

Is there a rubber stop somewhere that I'm missing that is allowing the window to go too far down?

I tried popping in another (working) regulator/motor and got the same result. Frustrating.

My concern is that the door/ door track is warped or bent and is causing the regulators to sieze.


Thoughts? Suggestions? all appreciated
