The car is a Mercedes 1973, 280 SE 4.5. How do I remove the regulator to replace it or fix the gear teeth. I have removed the door panel but the regulator is behind the door wall. Would appreciate info describing steps of removal the mechanism.
Thank you in advance.

in my 190 I did this-
1) lower the window half-way, undo the retaining screws securing the window.
2) undo 2-3 screws near the front of the door securing the regulator. there may be more screws
3) remove the regulator through an opening in the door.
Oh, unplug the motor wires-motor is attached to the regulator.
4) swap the motor to a new regulator. I don't see how you could repair the teeth,
5) install the whole shebang back where it belongs

Took me about 1 hour. The trick is to find the screws securing the regulator through the door panel

Good info from the previous poster. If that doesn't apply, there are "tips" in some of the threads here:
