Thanks karthief and mikestang 63 I removed the faulty motor thanks to you guys. The replacement motor I purchased did not match, I think it is for front LHS door, however I stripped down the old motor and the armature gear was jammed with the winder gear, I removed armature and reassembled the motor and it worked fine. There is an adjust screw/ lock nut on top of the motor does it need adjusting to prevent future gear lockups in the future.
