SEAT SWITCH
DESCRIPTION
Vehicles equipped with a driver side power seat
utilize an eight-way power seat switch. Vehicles
equipped with a passenger side power seat utilize a
four-way power seat switch. These power seat
switches features two knobs ganged together on the
outboard seat cushion side shield (Fig. 2).
The switch is secured to the back of the seat cush-
ion side shield with two screws. However, the control
knobs for the seat switch unit must be removed
before the seat switch can be removed from the side
shield.The power seat switch cannot be repaired. If one
switch is damaged or faulty, the entire power seat
switch unit must be replaced.
OPERATION
When a 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
DRIVER SEAT SWITCH
(1) Remove the power seat switch, (Refer to 8 -
ELECTRICAL/POWER SEATS/DRIVER SEAT
SWITCH - REMOVAL).
(2) Using an ohmmeter, check pin #1 of the power
seat switch wire harness connector for continuity to
ground. It should be present. If OK, go to Step 3. If
not OK, repair the open ground circuit as required.
(3) Using a voltmeter, check pin #5 of the power
seat switch wire harness connector for battery cur-
rent. It should be present. If OK, go to Step 4. If not
OK, repair the open voltage supply circuit as
required.
(4) Using an ohmmeter, test the power seat switch
for continuity, refer to SEAT SWITCH CONTINUITY
TEST TABLE (Fig. 3). If continuity is not present as
indicated, replace the power seat switch.

REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Using a push pin remover or other suitable
wide flat-bladed tool, gently pry the power seat and
power recliner switch knobs off of the switch levers
(Fig. 4).
(3) Remove the screws that secure the outboard
seat cushion side cover to the seat cushion frame,
(Refer to 23 - BODY/SEATS/SEAT CUSHION SIDE
COVERS - REMOVAL).
(4) Pull the outboard seat cushion side cover away
from the seat cushion frame far enough to access the
power seat switch wire harness connector.
(5) Disconnect the power seat wire harness connec-
tor from the power seat switch connector receptacle.
(6) Remove the screws that secure the power seat
switch to the inside of the outboard seat cushion side
cover.
(7) Remove the power seat switch from the out-
board seat cushion side cover.
INSTALLATION
(1) Position the power seat switch onto the out-
board seat cushion side cover.
(2) Install and tighten the screws that secure the
power seat switch to the inside of the outboard seat
cushion side cover. Tighten the screws to 1.5 N´m (14
in. lbs.).
(3) Reconnect the power seat wire harness connec-
tor to the power seat switch connector receptacle.(4) Install the outboard seat cushion side cover,
(Refer to 23 - BODY/SEATS/SEAT CUSHION SIDE
COVERS - INSTALLATION).
(5) Install the power seat and power recliner
switch knobs onto the switch control levers.
(6) Reconnect the battery negative cable.
MEMORY SWITCH
DESCRIPTION
Vehicles equipped with the memory system have a
memory switch mounted to the driver side front door
trim panel (Fig. 5). This switch is used to set and recall
all of the memory system settings for up to two drivers.
The memory switch is a resistor multiplexed unit that
is hard wired to the Body Control Module (BCM). The
BCM sends out the memory system set and recall
requests to the other electronic modules over the Pro-
grammable Communications Interface (PCI) data bus.
The memory switch cannot be adjusted or repaired
and, if faulty or damaged, it must be replaced.
OPERATION
The memory switch has three momentary switch
buttons labeled Set, 1 and 2. When the memory set
switch is depressed, a resistance value is sent to the
Body Control Module (BCM) via hard wired connec-
tions. When the memory system is in ªsetº mode a
chime will be generated by the BCM.

DIAGNOSIS AND TESTING
MEMORY SWITCH
(1) Remove the memory switch from the drivers
door panel (Refer to 8 - ELECTRICAL/POWER
SEATS/MEMORY SET SWITCH - REMOVAL).
(2) Using an ohmmeter, check the continuity of the
memory select switch MUX circuit between the C2
wire harness connector for the Body Control Module
(BCM) and the wire harness connector for the mem-
ory switch. There should be continuity. If OK, go to
Step 3. If not OK, repair the open or shorted MUX
circuit as required.
(3) Using an ohmmeter, check the continuity of the
memory select switch return circuit between the C2
wire harness connector for the BCM and the wire
harness connector for the memory switch. There
should be continuity. If OK, go to Step 4. If not OK,
repair the open or shorted return circuit as required.
(4) Using an ohmmeter, test the resistances of the
memory switch, refer to the MEMORY SWITCH
TEST TABLE. If OK, (Refer to 8 - ELECTRICAL/
POWER SEATS - DIAGNOSIS AND TESTING -
MEMORY SYSTEM). If not OK, replace the memory
switch, (Refer to 8 - ELECTRICAL/POWER SEATS/
MEMORY SET SWITCH - REMOVAL).

from the driver side front door. Using a thin flat-
bladed pry tool, gently pry the switch bezel away
from the drivers door trim panel.
(3) Disconnect the memory switch wire harness
connector from the memory switch.
(4) Remove the two screws that secure the memory
switch to the back of the driver side front door trim
panel switch bezel.
(5) Remove the memory switch.
INSTALLATION
(1) Position the memory switch and install and
tighten the two screws that secure the memory
switch to the back of the driver side front door trim
panel switch bezel. Tighten the screws to 2.2 N´m (20
in. lbs.).
(2) Reconnect the memory switch wire harness
connector to the memory switch.
(3) Install the trim panel switch bezel onto the
driver side front door.
(4) Reconnect the battery negative cable.
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.
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
