Hmmm,
Door repair step one,
Remove floor.......
Mass produced cheap out would probably have it driven with a nylon gear and/or a nylon flex strip like a late model power window. Just wait till that strips out.............
Manual override, a small knob in the trunk that cramps your hand getting the door back up after an hour of turning.....
Wait! What if the door sticks in the up position???????
Looks like I picked the wrong week to quit sniffing glue.....
