Just to add my cents worth ,if i can.The repair is fine . I replaced the whole item .The time i did mine i noticed after door card was removed ,that the deadening pads fixed to the inner door, had lifted all along the top edge .So as they were curling up, water was getting to the rear of them.With dirt and water it was going to rust out .Also a chance that if the pads do come away from the door they can fall on to the regulator arm and damage the motor as it is lifting the glass up. Just check it out .I am in a cold climate.If it can happen here i know it will in your locations.
