Bought this OEM widow motor from Nissan through a dealer about 5 years ago for my '86. Took the door panel off and new motor not needed, regulator was just out of alignment and jamming. Easy fix.

This motor sat around my parts box for a couple of years. Still new since never used, should work perfectly or just send it back. $90 plus $10 shipping. Paypal is cool. Msg me if interested.
