That part number appears to be for the motor and attachment gear. 8 years ago with my 91 the window did the same thing. The motor was worn out. I researched all the Bosch window motors (which are for the most part pretty generic) and found one on EBay that came off a low mileage BMW. I swapped my Bosch motor the Bosch BMW motor and it has worked as it should ever since even better than the passenger side. Only adjustment was I had to seal the cable to motor better to keep moisture out as this was for a sedan not an off-road vehicle.
Or if you don't want to fiddle with it you could possibly buy one of these:
