POWER SEAT TRACK
DESCRIPTION
The power seat track incorporates a front and rear
riser (Fig. 3). These risers are not part of the power
seat track and must be removed in order to service
the power seat track assembly. One 12v motor is uti-
lized in the power seat track (Fig. 3). The motor is
connected to a worm-drive gearbox that moves the
seat adjuster up and down. The drivers front seat
can be raised or lowered using the power seat switch,
located on the outboard side of the seat cushion side
shield.
The motor contains a self-resetting circuit breaker
to protect it from overload. Consecutive or frequent
resetting of the circuit breaker may cause damage to
the motor or circuit breaker.
The power seat track cannot be repaired, and is
serviced only as a complete assembly. If any compo-
nent in this unit is inoperative or damaged, the
entire power seat track assembly must be replaced.
OPERATION
One single armature permanent magnet reversible
motor is coupled to a worm gear box assembly. It is
located in between the seat tracks and upper sup-
ports. The one single gear motor assembly attaches
to the seat tracks and provide the various seat move-
ments.
The electrical circuit is protected by a 20 amp cir-
cuit breaker located in the junction block.
When a power seat switch is actuated, a battery
feed and a ground path are applied through the
switch contacts to the appropriate motor. The motor
and drive operate to move the seat in the selected
direction until the power seat switch is released, or
until the travel limit of the power seat track adjuster
is reached. When the power seat switch is moved in
the opposite direction, the battery feed and ground
path to the motor are reversed through the switch
contacts. This causes the motor and drive to run in
the opposite direction.
DIAGNOSIS AND TESTING - POWER SEAT
TRACK

The wiring information includes wiring diagrams,
proper wire and connector repair procedures, further
details on wire harness routing and retention, as well
as pin-out and location views for the various wire
harness connectors, splices and grounds.
