POWER MIRRORS
DESCRIPTION
If equipped with power mirrors, the control switch
is located on the instrument panel to the left of the
headlamp switch.
OPERATION
The power mirrors are connected to battery feed at
all times. Each mirror head contains two electric
motors, two drive mechanisms, an electric heating
element, and the mirror glass. If the vehicle is
equipped with the optional memory system, the
driver side mirror head also contains both a horizon-
tal and a vertical motor position sensor. One motor
and drive controls mirror up-and-down movement,
and the other controls right-and-left movement.An optional driver side outside electrochromic mir-
ror is able to automatically change its reflectance
level. This mirror is controlled by the circuitry of the
automatic day/night inside rear view mirror. A thin
layer of electrochromic material between two pieces
of conductive glass make up the face of the mirror.
Two photocell sensors on the inside rear view mirror
are used to monitor light levels and adjust the reflec-
tance of both the inside and driver side outside mir-
rors. This change in reflectance helps to reduce the
glare of headlamps approaching the vehicle from the
rear. (Refer to 8 - ELECTRICAL/POWER MIRRORS/
AUTOMATIC DAY / NIGHT MIRROR - DESCRIP-
TION) for more information on this system.
The motors which operate the mirrors are part of
the mirror assembly and cannot be serviced sepa-
rately.
8N - 26 POWER MIRRORSRS

AUTOMATIC DAY / NIGHT
MIRROR
DESCRIPTION
An automatic dimming inside day/night rear view
mirror and an automatic dimming driver side outside
rear view mirror are available factory-installed
options on this model. Following is a general descrip-
tion of this optional equipment.
The automatic day/night mirror is able to automat-
ically change its reflectance. A thin layer of electro-
chromic material between two pieces of conductive
glass make up the face of the mirror. Two photocell
sensors are used to monitor light levels and adjust
the reflectance of the mirror to reduce the glare of
headlamps approaching the vehicle from the rear.
For removal procedures, (Refer to 23 - BODY/IN-
TERIOR/REAR VIEW MIRROR - REMOVAL).
OPERATION
The ambient photocell sensor faces forward, to
detect the outside light levels. A second sensor faces
rearward to detect the light level received through
the vehicles back window. When the difference
between the two light levels becomes too great (the
light level received at the rear of the mirror is much
higher than that at the front of the mirror), the mir-
ror begins to darken.
The mirror switch allows the driver a manual con-
trol of whether the automatic dimming feature is
operational. When AUTO is selected a small Light-
Emitting Diode (LED), to the right of the mirror
switch, is illuminated. The automatic dimming fea-
ture will only operate when the ignition switch is in
the On position. The mirror also senses the backup
lamp circuit, and will automatically disable its self-
dimming feature whenever the transmission gear
selector is in the Reverse position.
NOTE: The mirror always defaults to an ON state
upon ignition.
The driver side automatic dimming mirror is stan-
dard with the automatic dimming inside mirror. The
signal to control the dimming of that mirror is gen-
erated by the automatic day/night inside rear view
mirror circuitry. That signal is then delivered to the
driver side outside rear view mirror on a hard wired
circuit.
The automatic day/night mirror cannot be
repaired. If faulty or damaged, the entire inside rear
view mirror assembly must be replaced.
DIAGNOSIS AND TESTING
AUTOMATIC DAY / NIGHT MIRROR
For circuit descriptions and diagrams, refer to the
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds.
(1) Check the fuse in the intelligent power module.
If OK, go to Step 2. If not OK, repair the shorted cir-
cuit or component as required and replace the faulty
fuse.
(2) Turn the ignition switch to the On position.
Check for battery voltage at the fuse in the intelli-
gent power module. If OK, go to Step 3. If not OK,
repair the open circuit to the ignition switch as
required.
(3) Unplug the wire harness connector from the
automatic day/night mirror. Check for battery voltage
at the fused ignition switch output circuit cavity of
the automatic day/night mirror wire harness connec-
tor. If OK, go to Step 4. If not OK, repair the open
circuit to the junction block as required.
(4) Turn the ignition switch to the Off position.
Check for continuity between the ground circuit cav-
ity of the automatic day/night mirror wire harness
connector and a good ground. There should be conti-
nuity. If OK, go to Step 5. If not OK, repair the cir-
cuit to ground as required.
(5) Turn the ignition switch to the On position. Set
the parking brake. Place the transmission gear selec-
tor lever in the Reverse position. Check for battery
voltage at the backup lamp switch output circuit cav-
ity of the automatic day/night mirror wire harness
connector. If voltage is present, reinstall the auto-
matic day/night mirror wire harness connector and
go to Step 6. If not OK, repair the open circuit as
required.
(6) Place the transmission gear selector lever in
the Neutral position. Place the automatic day/night
mirror switch in the On (LED in the switch is
lighted) position. Cover the forward facing ambient
photocell sensor to keep out any ambient light.
NOTE: The ambient photocell sensor must be cov-
ered completely, so that no light reaches the sen-
sor. Use a finger pressed tightly against the sensor,
or cover the sensor completely with electrical tape.
(7) Shine a light into the rearward facing head-
lamp photocell sensor. The automatic day/night mir-
ror should darken. The automatic day/night mirror
should darken within 2 minutes if testing for the
first time. For immediate response, turn the vehicle
8N - 28 POWER MIRRORSRS

OFF and back ON with the forward-facing light sen-
sor still covered. This defeats the day-detect logic. If
OK, go to Step 8. If not OK, replace the faulty mirror
unit.
(8) With the mirror darkened, place the transmis-
sion gear selector lever in the Reverse position. The
automatic day/night mirror should return to its nor-
mal reflectance. If not OK, replace the faulty mirror
unit.
Bench testing both mirrors can be done, of care is
exercised. For an inside mirror, the pin closest to he
mount is 12V (+), the next is 12V (-). The third is
reverse override. The fourth is outside mirror (+), and
the fifth is outside mirror (-).Do not apply 12 volts to
the fourth and fifth pins.With 12 volts on pins 1 and
2, the mirror can be tested by blocking the rear sensor
and shining a light into the forward sensor. For an out-
side mirror, there is a 2±pin connector. Applying 1.2
volts will cause the mirror to dim. If the mirror does not
dim, the entire glass assembly can be replaced just as it
is when the glass is broken.
WARNING: Do not apply 12 volts to the outside mir-
ror. Damage to the mirror will result.
POWER FOLDAWAY MIRROR
SWITCH - EXPORT
DESCRIPTION
These vehicles may be equipped with Power Fold-
away Mirrors. This feature allows both the driver
and passenger side view mirrors to fold inward
(retract) on demand. The vehicle has an additional
switch located on the steering column that controls
the folding function of the mirror assembly (Fig. 2).
The fold-away side view mirror is attached to the
vehicle's door in the same manner as mirrors without
the fold-away option. The fold-away mirrors unique
option is the internal motor which allows the mirrors to
fold inward on demand. The fold-away mirror motor is
not serviceable separately and if a motor is found to be
faulty the entire side view mirror must be replaced.
OPERATION
When the mirror retract switch is depressed, both
of the side view mirrors will fold inward, Thus mak-
ing the overall width of the vehicle the smallest pos-
sible. This can be helpful were parking space is a
absolute minimum.
When the driver's door is opened, only the driver's
door mirror will unfold. If the passenger door is
opened, both mirrors will unfold.
The power fold away mirror system consists of the fol-
lowing components: mirror switch, side view mirror,relay, wires and fuse. 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, connector
pin-out information and location views for the various
wire harness connectors, splices and grounds.
REMOVAL
(1)Disconnect and isolate the battery negative cable.
(2) Remove the upper and lower steering column
shroud (Refer to 19 - STEERING/COLUMN/LOWER
SHROUD - REMOVAL).
(3) Disconnect electrical harness connector.
(4) Remove switch from steering column shroud
(Fig. 3).

POWER SEAT SYSTEM
DESCRIPTION
POWER SEAT SYSTEM
The power seat system option allows the driver
and front seat passenger to electrically adjust their
seating positions for optimum control and comfort.
The driver side power front seat can be adjusted in
eight different directions: up, down, front up, front
down, rear up, rear down, forward, rearward and
recliner forward and rearward. The passenger side
power front seat can be adjusted in four different
directions: forward, rearward and recliner forward
and rearward.
The power seat system receives battery current
through a 40 amp fuse in the Integrated Power Mod-
ule (IPM) and a 30 amp circuit breaker under the
seat so that the power seats remain operational,
regardless of the ignition switch position.
WARNING: SOME VEHICLES ARE EQUIPPED WITH
SEATBACK MOUNTED AIRBAGS (Fig. 1). 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 COULDRESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND POSSIBLE PERSONAL INJURY.
The eight-way driver side power seat is also avail-
able with the heated seat and/or memory seat sys-
tem. The memory seat system automatically
positions the power seat for two different drivers.

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
RSPOWER SEAT SYSTEM8N-37
MEMORY SWITCH (Continued)

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

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 certainthat 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 -
