STANDARD PROCEDURE
GRID REPAIR PROCEDURE
WARNING: Materials contained in the Repair Kit
(Part Number 04549275) may cause skin or eye irri-
tation. The kit contains epoxy resin and amine type
hardener, which are harmful if swallowed. Avoid
contact with the skin and eyes. For skin contact,
wash the affected areas with soap and water. For
contact with the eyes, flush with plenty of water. Do
not take internally. If taken internally, induce vomit-
ing and call a physician immediately. Use with ade-
quate ventilation. Do not use near fire or flame.
Contains flammable solvents. Keep out of the reach
of children. Failure to follow the warnings could
result in possible personal injury or death.
Repair of the rear glass heating grid lines, bus
bars or terminals can be accomplished using the
MopartRear Window Defogger Repair Kit (Part
Number 04549275) or equivalent.
(1) Mask the repair area with masking tape so
that the conductive epoxy can be applied neatly (Fig.
6). Extend the epoxy application onto the grid line or
the bus bar on each side of the break.
(2) Follow the instructions in the repair kit for
preparing the damaged area.
(3) Remove the package separator clamp and mix
the two conductive epoxy components thoroughly
within the packaging. Fold the package in half and
cut the center corner to dispense the epoxy.
(4) For grid line repairs, mask the area to be
repaired with masking tape or use a template.
(5) Apply the epoxy through the slit in the mask-
ing tape or template. Overlap both ends of the break
by at least 19 millimeters (0.75 inch).
(6) For a terminal replacement, mask the adjacent
areas so the epoxy can be extended onto the adjacent
grid line as well as the bus bar. Apply a thin layer of
epoxy to the area where the terminal was fastened
and onto the adjacent grid line.(7) Apply a thin layer of conductive epoxy to the
terminal and place it in the proper location on the
bus bar. To prevent the terminal from moving while
the epoxy is curing, it must be wedged or clamped.
(8) Carefully remove the masking tape or tem-
plate.
CAUTION: Do not allow the glass surface to exceed
204É C (400É F) when using a heat gun, or the glass
may fracture.
(9) Allow the epoxy to cure 24 hours at room tem-
perature, or carefully use a heat gun for fifteen min-
utes. When using a heat gun, hold it approximately
25.4 centimeters (10 inches) from the repair and do
not allow the glass surface to exceed 204É C (400É F).
NOTE: Do not attach the wire harness connectors
to the terminals until the curing process is com-
plete.
(10) After the conductive epoxy is properly cured,
remove the wedge or clamp from the terminal.
(11) Connect the wire harness leads to the grid
terminals and verify EBL operation.

HEATED MIRRORS
DESCRIPTION
The optional heated mirror system is controlled by
the momentary rear window defogger switch which is
integral to the A/C-heater control (Fig. 1). An amber
indicator lamp in the switch will illuminate to indi-
cate when the rear window defogger (EBL) system is
turned on.
The heated mirror system only operates in concert
with the EBL system, and will be automatically shut
off after a programmed time interval of about 10
minutes. After the initial time interval has expired, if
the defogger switch is turned on again during the
same ignition cycle, the heated mirror system will
automatically shut off after about 5 minutes.
The heated mirror system will automatically shut
off if the ignition switch is turned to the Off position,
or it can be shut off manually by pressing the rear
window defogger switch a second time.
OPERATION
When the rear window defogger switch is pressed,
the rear window defogger (EBL) system becomes acti-
vated and an electric heater grid located behind the
glass of each of the outside rear view mirrors is ener-
gized. When energized, each of these heater grids
produce heat to help clear the outside rear view mir-
rors of ice, snow, or fog.If the outside mirror heating grids are both inoper-
ative, refer to DIAGNOSIS AND TESTING - REAR
WINDOW DEFOGGER SYSTEM in his group. If
only one of the outside mirror heating grids is inop-
erative, Refer to 8 - ELECTRICAL/POWER MIR-
RORS - DIAGNOSIS AND TESTING.
The heating grid behind each outside mirror glass
cannot be repaired and, if faulty or damaged, the
entire power mirror assembly must be replaced.

Hard wired circuitry connects the heated seat sys-
tem components to each other through the electrical
system of the vehicle. These circuits may be con-
nected to each other, to the vehicle electrical system
and to the heated seat system components through
the use of a combination of soldered splices and
splice block connectors. Refer to the appropriate wir-
ing information for complete circuit schematic or con-
nector pin-out information.
OPERATION
The heated seat system components operate on
battery current received through a fuse in the Inte-
grated Power Module (IPM) on a fused ignition
switch output (run) circuit from the Body Control
Module (BCM). The system will only operate when
the ignition switch is in the On position. The heated
seat system will be turned Off automatically when-
ever the ignition switch is turned to any position
except On. Also, the heated seat system will not oper-
ate when the surface temperature of the seat cushion
cover at either heated seat sensor is above the
designed temperature set points of the system.
DIAGNOSIS AND TESTING
HEATED SEAT SYSTEM
The most efficient means of diagnosing the heated
seat system is by individual component. For diagno-
sis of a specific component refer to the following:
²Heated seat module, (Refer to 8 - ELECTRICAL/
ELECTRONIC CONTROL MODULES/MEMORY
HEATED SEAT/MIRROR MODULE - DIAGNOSIS
AND TESTING).
²Heated seat elements, (Refer to 8 - ELECTRI-
CAL/HEATED SEATS/HEATED SEAT ELEMENT -
DIAGNOSIS AND TESTING).
²Heated seat switch, (Refer to 8 - ELECTRICAL/
HEATED SEATS/DRIVER HEATED SEAT SWITCH
- DIAGNOSIS AND TESTING).
²Heated seat sensor, (Refer to 8 - ELECTRICAL/
HEATED SEATS/HEATED SEAT SENSOR - DIAG-
NOSIS AND TESTING).
Refer to the appropriate wiring information for
complete circuit schematic or connector pin-out infor-
mation.
HEATED SEAT SWITCH
DESCRIPTION
The heated seat switches are mounted in the
instrument panel center bezel (Fig. 2). The two three-
position rocker-type switches, one switch for each
front seat, are incorporated into one large switch
assembly that also includes the hazard, rear window
wiper and washer switches. Each heated seat switch
provides a resistor multiplexed signal to its respec-
tive Heated Seat Module (HSM) through separate
hard wired circuits. Each switch has an Off, Low,
and High position so that both the driver and the
front seat passenger can select a preferred seat heat-
ing mode. Each switch has two Light-Emitting
Diodes (LED) which light to indicate that the heater
for the seat is turned on.
The heated seat switches and their LEDs cannot
be repaired. If either switch or LED is faulty or dam-
aged, the entire switch assembly must be replaced.

SWITCH - EXPORT
DESCRIPTION
The Door Cylinder Lock Switch (If equipped) is
used to:
²Unlock/Lock all the doors via the Central Lock-
ing feature.
²Arm/Disarm the Vehicle Theft Security System.
²Trigger the Illuminated Entry feature.
The door cylinder lock switch is mounted to the
rear of the driver door lock cylinder. When installed
on the rear of the cylinder, there is a tab on the lock
cylinder that aligns with the switch to prevent it
from turning. An anti-rotating device. The door cylin-
der lock switch is a one time use switch. Once it is
removed from the rear of the door lock cylinder, it
may not be reinstalled and a new switch must be
used.
OPERATION
When the Door Cylinder Lock Switch is turned
either way using the door key cylinder, the BCM
reads a direct message signal from the switch.
If turning the key cylinder once, toward the front
of the vehicle, this will:
(1) Mechanically unlock the door lock.
(2) Disarm the Vehicle Theft Security System (if
equipped).
(3) Turn on the Illuminated Entry (if equipped) for
approximately 30 seconds.
If the key cylinder is turned to the unlock position
(toward the front of vehicle) twice within two sec-
onds, all the doors and liftgate will unlock (if
equipped with the central locking feature).
To lock the vehicle using the door cylinder lock
switch, turn the key cylinder toward the rear of the
vehicle once. This will lock the door that you are
using the key on. If equipped with the central locking
feature, this will lock all the other doors and liftgate.
Furthermore, this will arm the vehicle theft security
system and turn off the illuminated entry.

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
