POWER SEAT TRACK
DESCRIPTION
The power seat option includes an electrically oper-
ated power seat track located under the front seat. If
equipped with Memory System, the front power seat
track on the driver side of the vehicle also provides
the mounting location for the Memory Seat/Mirror
Module (MSMM). The power seat circuit breakers are
mounted on the rear of the power seat track, just
behind the seat rear trim panel. The lower half of the
power seat track is secured to the floor panel via four
studs and nuts that must be accessed from the
underside of the vehicle. Four bolts secure the bot-
tom of the seat cushion pan to the upper half of the
power seat track unit. Four additional bolts secure
the seat back frame to the power seat track unit.
The eight-way power seat track unit includes four
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. Each of the
four power seat track motors used on models
equipped with the optional memory system incorpo-
rate a position potentiometer integral to the motor
assembly, which electronically monitors the motor
position. This enables the memory system to function
by referencing the motor positions programmed into
the memory seat/mirror module.

MEMORY SWITCH (Continued)
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. They
can also be operated in unison by selecting the
proper power seat switch functions, which will raise
or lower the entire seat assembly. A third motor is
the horizontal adjustment motor, which moves the
seat track in the forward and aft directions. The
forth motor is the recliner adjustment motor, which
moves the seat back in the forward and rearward
directions.
The four-way power seat track unit includes two
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 horizontal
adjustment motor moves the seat track in the for-
ward and aft directions. The recliner adjustment
motor moves the seat back in the forward and rear-
ward directions.
The power seat track unit cannot be repaired, and
is serviced only as a complete unit. If any component
in this unit is faulty or damaged, the entire power
seat track unit must be replaced.
OPERATION
When the power seat switch control knob or knobs
are actuated, a battery feed and a ground path are
applied through the switch contacts to the power seat
track
or
recliner
adjuster
motor.
The
selected
adjuster motor operates to move the seat track or
recliner through its drive unit in the selected direc-
tion until the switch is released, or until the travel
limit of the adjuster is reached. When the 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 adjuster motor to
run in the opposite direction.
No power seat switch should be held applied in any
direction after the adjuster has reached its travel
limit. The power seat adjuster motors each contain a
self-resetting circuit breaker to protect them from
overload. However, consecutive or frequent resetting
of the circuit breaker must not be allowed to con-
tinue, or the motor may be damaged.
DIAGNOSIS AND TESTING
POWER SEAT TRACK
WARNING: SOME VEHICLES ARE EQUIPPED WITH
SEATBACK
MOUNTED
AIRBAGS.
BEFORE
ATTEMPTING TO DIAGNOSE OR SERVICE ANY
SEAT OR POWER SEAT SYSTEM COMPONENT
YOU MUST FIRST DISCONNECT AND ISOLATE THE
BATTERY NEGATIVE CABLE. THEN WAIT TWO MIN-
UTES FOR THE SYSTEM CAPACITOR TO DIS-
CHARGE BEFORE FURTHER SYSTEM SERVICE.
THIS IS THE ONLY SURE WAY TO DISABLE THE
AIRBAG SYSTEM. FAILURE TO DO SO COULD
RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND POSSIBLE PERSONAL INJURY.
Actuate the power seat switch to move the power
seat track adjusters in each direction. The power seat
track adjusters should move in each of the selected
directions. If a power seat track adjuster operates in
one direction only, move the adjuster a short distance
in the opposite direction and test again to be certain
that the adjuster is not at its travel limit. If the
power seat track adjuster still operates in one direc-
tion
only,
(Refer
to
8
-
ELECTRICAL/POWER
SEATS/DRIVER SEAT SWITCH - DIAGNOSIS AND
TESTING). If the power seat track adjuster does not
operate in more than one direction, perform the fol-
lowing tests.
TESTING POWER SEAT TRACK MOTORS
(1) Check the power seat circuit breaker under the
seat. If OK, go to Step 2. If not OK, replace the
faulty power seat circuit breaker.
(2) Check for battery voltage at the power seat cir-
cuit breaker under the seat. If OK, go to Step 3. If
not OK, repair the open fused B(+) circuit to the fuse
in the Integrated Power Module (IPM) as required.
(3) Remove the outboard seat cushion side cover,
(Refer to 23 - BODY/SEATS/SEAT CUSHION SIDE
COVERS - REMOVAL). Disconnect the wire harness
connector from the power seat switch. Check for bat-
tery voltage at the fused B(+) circuit cavity of the
power seat switch wire harness connector. If OK, go
to Step 4. If not OK, repair the open fused B(+) cir-
cuit to the power seat circuit breaker under the seat
as required.
(4) Check for continuity between the ground cir-
cuit cavity of the power seat switch wire harness con-
nector and a known good ground. There should be
continuity. If OK, go to Step 5. If not OK, repair the
open ground circuit as required.
(5) Test the power seat switch, (Refer to 8 - ELEC-
TRICAL/POWER SEATS/DRIVER SEAT SWITCH -
DIAGNOSIS AND TESTING). If the switch tests OK,
test the circuits of the power seat wire harness
between the inoperative power seat track adjuster
motor and the power seat switch for shorts or opens.
If the circuits check OK, replace the faulty power
seat track unit. If the circuits are not OK, repair the
power seat wire harness as required.
