Driver side power window motor replacement
My 98 ML320's window went down and cannot get it back up.
I pulled the motor out and tried it without window. When I click
"down", motor will run. (and the meter will read +12 V coming).
When I click "up", motor will not run, and the meter will read -12 V.
I think the motor is partially bad, not the regulator, which is the
part connect motor to the window.
Any one with experience or knowledge, please comment.
