'89 200Q stuck rear power windows

[Michael, Dave]

Larry

I have run into this on my 90 200QA. I fixed it on the LR window by
removing the motor and cleaning the armature according to the procedure
in the Bently. If applying 12V to motor leads (remove the door panel)
directly does not move the motor, then this is will likley fix it. The
rear windows get used so infrequently that the copper corrodes. The
armature contacts were brown, not shiny copper. Cleaned them up with and
eraser and the window works fine now. Onto the passenger side.
