Cadillac Buick Chevrolet GMC Oldsmobile Pontiac
Years: 1979-88
Replaces Part No. 20113995, 20449101
*The same unit is used on both the driver's seat and passenger seat. 

This Seat Motor is remanufactured and comes with a 5 Year Warranty.  We disassemble each motor and clean the bushings, polish the commutator, and fit a new thrust washer. It is re-assembled, tested, and shipped to you ready for installation.

IMPORTANT NOTE: The Power Seat system is an antique. It is not an amusement park ride. It was NEVER designed for continuous use. Continuous use will overheat the bushings and lock or break the transmission. Move it to the position you like and leave it there. Do not repeatedly hit the end of the track going back and forth, and up and down. Unlike modern power seats that have current sensing, limit switches, and constant position monitoring, these systems do not even have a rubber cushion at the end of travel.


After installing your new unit, ship your old unit (core) to Proper Parts within 30 days to receive your core refund. Your purchase receipt must be enclosed to process your refund. 

We ship within 1 to 2 business days. 

Please return your core within 30 days. After 45 days, a late fee of 10% will be charged. Your refund will be credited to your original payment method when we receive your core.
