MEMORY SEAT SYSTEM
below.
The power seat system for this vehicle includes the
following major components:
•
Power Seat Adjuster - The power seat adjuster
is made up of the upper and lower power seat
adjuster assemblies. The driver upper power seat
adjuster contains two reversible motors that are
connected to worm-drive gearboxes that move
the seat adjuster through a combination of
screw-type drive units. These motors are the
height adjust motor and the front tilt motor. On
vehicles equipped with non-memory power seats,
each
motor
contains
a
self-resetting
circuit
breaker to protect it from overload. On vehicles
equipped with memory power seats the motor
overload protection is a function of the Memory
Seat Module (MSM). Consecutive or frequent
resetting of the circuit breakers may damaged
the motors. There are no motors on the passenger upper power seat adjuster.
The height adjust motor is located on the rear of the upper power seat adjuster assembly and controls the up
and down movement of the entire seat. The height adjust motor can be serviced separately from the power
seat adjuster assembly.
