Description & Operation

A 6-way power seat is used on driver's seat and passenger seat (some models). System consists of 3 reversible motors attached to a seat drive rail. Some systems use a 4th motor for seatback recline. Each motor contains a self-resetting circuit breaker. Power seat switch is located on left side of driver's seat, or on right side of passenger's seat. Drive cables connect motor to gearnuts, which turn jack screws and adjusters at each side of seat.

The 8-way power seat incorporates a power seat recline feature. Power lumbar support is also an option, allowing power operation of lumbar support. Memory seats are available as an option on driver's seat. Seat memory module tracks seat location through position sensors (transducers) on seat adjusting motors
