My driver's side front window motor stopped working. It's getting voltage but no sound from the motor. I've got the motor cover off and the armature is rusted, but I think it'll work after cleaning. The part I can't get is how to remove the whole armature/worm gear without taking the whole gear box off the window regulator? I turned the armature as far as she'll go either way until the regulator pops at the end of its track but still won't come off. I could swear I remember reading guys were able to get the worm gear out without taking the whole gear housing off the track. I searched but can't find it now. How do I get the whole armature/worm gear out of the gear housing? Thanks.
