POWER SEAT TRACK
DESCRIPTION
The six-way power seat option includes a power seat
track assembly (3) located under each front seat cush-
ion frame (2). 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 one bolt and one nut to the floor panel.
Four bolts 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. Each of the three driver side power seat track motors also has a position potentiometer integral to the motor
assembly, which electronically monitors the motor position.
The front and rear of the seat are operated by two separate vertical adjustment motors. These motors can be oper-
ated independently of each other, tilting the entire seat assembly forward or rearward; or, they can be operated in
unison by selecting the proper power seat switch functions, which will raise or lower the entire seat assembly. The
third motor is the horizontal adjustment motor, which moves the seat track in the forward and rearward directions.
DIAGNOSIS AND TESTING - POWER SEAT TRACK
1. Remove the power seat switch from the seat (Refer to 8 - ELECTRICAL/POWER SEATS/DRIVER SEAT
SWITCH - REMOVAL).
2. Checking the body harness side of the power seat
switch electrical connector, check Pin 1 for ground
and Pin 5 for battery voltage. If either of these two
are not present repair the body harness as
required.
3.
To test the seat motors and verify proper seat
responses, refer to the SEAT TRACK MOTOR
TEST TABLE . Using two jumper wires, connect
one to a battery supply and the second to a
ground. Connect the other ends to the seat wire
harness connector as described in the SEAT
TRACK MOTOR TEST TABLE .

DESCRIPTION
WARNING: Keep fingers and other body parts out of sunroof opening at all times.
The power sunroof system allows the sunroof to be opened, closed or placed in the vent position electrically by
actuating a switch located in the overhead console in between the two reading lamps. The sunroof system receives
battery feed through a 30 amp circuit breaker in the junction block. The sunroof system power is supplied when the
ignition switch is in the RUN and ACCESSORY positions. The sunroof will continue to operate normally with the key
in the OFF position or with the key removed while the Accessory Delay System is active.
The sunroof glass panel tilts upward at the rear for ventilation and slides rearward under the roof when open. The
panel seals flush with the roof in the closed position to eliminate wind noise. The sunroof includes a manual-sliding
sunshade to cover the deep-tinted glass panel.
The sunroof is electrically operated from a combination push-button/rocker style switch located in the overhead con-
sole in between the two reading lamps. The “VENT” switch is a push button type switch and opens the sunroof to
the vent position only. The other switch “OPEN/CLOSED” is a rocker type switch for opening and closing the sun-
roof. Pressing and releasing the open button once, the sunroof will express open and the wind deflector will raise.
If the button is pressed a second time the sunroof will stop in that position. Pressing and holding the close button
will close the sunroof. If the close button is released the sunroof will stop in that position.
OPERATION
This vehicle has a vent, tilt and slide power sunroof system with express (one-touch) open feature. The sunroof
system receives battery feed through the “sunroof” relay and a 20 amp mini fuse located in the junction block. The
sunroof system power is supplied when the ignition switch is in the RUN and ACCESSORY positions. The sunroof
will operate normally with the key in any position while the Accessory Delay system is active.
The sunroof is electrically operated from two switches located in the overhead console in between the two reading
lamps. The “VENT” switch is a push button type switch and opens the sunroof to the vent position only. The other
switch “OPEN/CLOSED” is a rocker type switch for opening and closing the sunroof. Pressing and releasing the
open button once, the sunroof will express open and the wind deflector will raise. If the button is pressed a second
time the sunroof will stop in that position. Pressing and holding the close button will close the sunroof. If the close
button is released the sunroof will stop in that position.
DIAGNOSIS AND TESTING
SUNROOF
Refer to SUNROOF DIAGNOSIS CHART for possible causes. Before beginning sunroof diagnostics verify that all
other power accessories are in proper operating condition. If not, a common electrical problem may exist.
Check the condition of the circuit protection and inspect all wiring connector pins for proper engagement and con-
tinuity. For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes
wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, con-
nector pin-out information and location views for the various wire harness connectors, splices and grounds.
