POWER SEAT TRACK
DESCRIPTION
The eight-way power seat option includes a power
seat track assembly located under each front seat
(Fig. 5). The power seat track assembly replaces the
standard manually operated seat tracks. The lower
half of the power seat track is secured at the front
with two bolts to the floor panel seat cross member,
and at the rear with two bolts to the floor panel.
Four nuts secure the bottom of the seat cushion
frame to the upper half of the power seat track unit.
The power seat track assembly cannot be repaired,
and is serviced only as a complete assembly. If any
component in this assembly is faulty or damaged, the
entire power seat track must be replaced.

OPERATION

The power seat track unit includes three reversible
electric motors that are secured to the upper half of
the track unit. Each motor moves the seat adjuster
through a combination of worm-drive gearboxes and
screw-type drive units.
The front and rear of the seat are operated by two
separate vertical adjustment motors. These motors
can be operated independently of each other, tilting
the entire seat assembly forward or rearward; or,
