I replaced a follower in the right rear door (88 300SEL). However, my window motor was working. The manual required that the window be in certain position so that the mechanisim could be withdrawn from the bottom of the door (assuming that you have removed the door panel). I would try to remove the motor from the sector gear thus allowing you to reposition the lever mechanisim and remove it from the door. Be sure to disconnect the window motor from power. This things are powerfull and can to major damage to your body parts.
