automatically change the reflectance of the inside
rear view mirror in order to reduce the glare of head-
lamps approaching the vehicle from the rear. The
automatic day/night rear view mirror receives bat-
tery current through a fuse in the junction block only
when the ignition switch is in the ON position.

OUTSIDE REAR VIEW MIRROR

The power operated outside rear view mirrors

allow the driver to adjust both outside mirrors elec-
trically from the driver side front seat position by
operating a switch on the instrument panel to the
left of the steering column.

OPERATION

AUTOMATIC DAY/NIGHT MIRROR

A switch located on the bottom of the automatic

day/night mirror housing allows the vehicle operator
to select whether the automatic dimming feature is
operational. When the automatic day/night mirror is
turned on, the mirror switch is lighted by an integral
Light-Emitting Diode (LED). The mirror will auto-
matically disable its self-dimming feature whenever
the vehicle is being driven in reverse.

OUTSIDE REAR VIEW MIRROR

The power mirrors receive a non-switched battery

feed through a fuse in the junction block so that the
system will remain operational, regardless of the
ignition switch position.

DIAGNOSIS AND TESTING - POWER MIRRORS

For complete circuit diagrams, refer to the appro-

priate wiring information.

(1) Disconnect and isolate the battery negative

cable.

(2) Remove the power mirror switch. (Refer to 8 -

ELECTRICAL/POWER MIRRORS/POWER MIRROR
SWITCH - REMOVAL).

(3) Disconnect wire connector from the switch.
(4) Using two jumper wires, one connected to a 12

volt battery source, and the other connected to a good
body ground. Refer to the Mirror Motor Test table for
appropriate mirror response, using the mirror switch
wiring harness connector (Fig. 1).

(5) If test results are not obtained as shown in the

Mirror Motor Test table, check for open or shorted
circuit, or replace mirror assembly as necessary.

If mirror motor tests OK, go to Mirror Switch Test.

AUTOMATIC DAY / NIGHT
MIRROR

DESCRIPTION

The automatic day/night mirror uses a thin layer

of electrochromic material between two pieces of con-
ductive glass to make up the face of the mirror.
When the mirror switch is in the On position, two
photocell sensors are used by the mirror circuitry to
monitor external light levels and adjust the reflec-
tance of the mirror.

OPERATION

The ambient photocell sensor is located on the for-

ward-facing (windshield side) of the rear view mirror
housing, and detects the ambient light levels outside
of the vehicle. The headlamp photocell sensor is
located inside the rear view mirror housing behind
the mirror glass and faces rearward, to detect the
level of the light being received at the rear window
side of the mirror. When the circuitry of the auto-
matic day/night mirror detects that the difference
between the two light levels is too great (the light
level received at the rear of the mirror is much
higher than that at the front of the mirror), it begins
to darken the mirror.

The automatic day/night mirror circuitry also mon-

itors the transmission using an input from the
backup lamp circuit. The mirror circuitry is pro-
grammed to automatically disable its self-dimming
feature whenever it senses that the transmission
backup lamp circuit is energized.

The automatic day/night mirror is a completely

self-contained unit and cannot be repaired. If faulty
or damaged, the entire mirror assembly must be
replaced.

DIAGNOSIS AND TESTING - AUTOMATIC
DAY/NIGHT INSIDE MIRROR

For complete circuit diagrams, refer to the appro-

priate wiring information.

(1) Check the fuse in the junction block. If OK, go

to Step 2. If not OK, repair the shorted circuit 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 junction
block. If OK, go to Step 3. If not OK, repair the open
circuit to the ignition switch as required.

(3) Turn the ignition switch to the Off position.

Disconnect and isolate the battery negative cable.
Unplug the wire harness connector from the auto-
matic day/night mirror. Connect the battery negative
cable. Turn the ignition switch to the On position.
Check for battery voltage at the fused ignition switch
output (run/start) circuit cavity of the automatic day/
night mirror wire harness connector. If OK, go to
Step 4. If not OK, repair the open circuit to the junc-
tion block as required.

(4) Turn the ignition switch to the Off position.

Disconnect and isolate the battery negative cable.
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) Connect the battery negative cable. Turn the

ignition switch to the On position. Set the parking
brake. Place the transmission gear selector lever in
the Reverse position. Check for battery voltage at the
backup lamp switch output circuit cavity of the auto-
matic day/night mirror wire harness connector. If
OK, go to Step 6. If not OK, repair the open circuit
as required.

(6) Turn the ignition switch to the Off position.

Disconnect the battery negative cable. Plug in the
automatic day/night mirror wire harness connector.
Connect the battery negative cable. Turn the ignition
switch to the On position. Place the transmission
gear selector lever in the Neutral position. Place the
mirror switch in the On (the LED in the mirror
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 mirror glass should
darken. If OK, go to Step 8. If not OK, replace the
faulty automatic day/night mirror unit.

(8) With the mirror glass darkened, place the

transmission gear selector lever in the Reverse posi-
tion. The mirror should return to its normal reflec-
tance. If not OK, replace the faulty automatic day/
night mirror unit.

POWER SEAT SYSTEM

DESCRIPTION

The power seat system on this model allows the

driver to electrically adjust their seating positions in
eight directions for optimum control and comfort,
using the power seat switch located on the outboard
seat cushion side shield (Fig. 1). The power seat sys-
tem receives battery current through a 40 amp fuse
in the Power Distribution Center (PDC) and a 20
amp circuit breaker in the junction block so that the
power seats remain operational, regardless of the
ignition switch position.

WARNING: SOME VEHICLES ARE EQUIPPED WITH
SIDE AIRBAGS. BEFORE ATTEMPTING TO DIAG-
NOSE OR SERVICE ANY SEAT OR POWER SEAT
SYSTEM COMPONENT YOU MUST FIRST DISCON-
NECT AND ISOLATE THE BATTERY NEGATIVE
CABLE. THEN WAIT TWO MINUTES FOR THE SYS-
TEM CAPACITOR TO DISCHARGE BEFORE FUR-
THER SYSTEM SERVICE. THIS IS THE ONLY SURE
WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE
TO DO SO COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.

The power seat system allows the seating position

to be adjusted forward, rearward, up, down, front up,
front down, rear up, or rear down. A eight-way power
seat is standard on premium models and optional on
others. This option includes a six-way adjustable seat
cushion track and a two-way power seat back. The
eight-way power seat is also available with the
heated seat system (Export Only). Refer to Heated
Seat System for more information on the heated

seat option. The power seat system includes the fol-
lowing components:

• Power seat switch

• Power seat track.

• Power seat system fuse and circuit breaker
Refer to Wiring Diagrams for complete circuit dia-

grams. Following are component descriptions, theory
of operation and removal and installation procedures
for the power seat system components.

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
