GENERAL INFORMATION
NS vehicles use lighting on the interior and exte-
rior of the vehicle for illuminating and indicating
purposes. Lighting circuits are protected by fuses.
Lighting circuits require an overload protected power
source, on/off device, lamps and body ground to oper-
ate properly. Plastic lamps require a wire in the har-
ness to supply body ground to the lamp socket.
Replace sockets and bulbs that are corroded.
Some of the interior and exterior lighting functions
are governed by the body controller. The headlamp,
dome, and the door ajar switches provide signals to
the body controller. The body controller in turn acti-
vates relay(s) in order to provide either a ground or
feed line to the appropriate lamp(s).
Wire connectors can make intermittent contact or
become corroded. Before coupling wire connectors,
inspect the terminals inside the connector. Male ter-
minals should not be bent or disengaged from the
insulator. Female terminals should not be sprung
open or disengaged from the insulator. Bent and
sprung terminals can be repaired using needle nose
pliers and pick tool. Corroded terminals appear
chalky or green. Corroded terminals should be
replaced to avoid recurrence of the problem symp-
toms.
Begin electrical system failure diagnosis by testing
related fuses in the fuse block and power distribution
center. Verify that bulbs are in good condition andtest continuity of the circuit ground. Refer to Group

DESCRIPTION AND OPERATION
INTRODUCTION
The electrically heated Rear Window Defogger (Fig.
1), Heated Power Side View Mirrors, and Heated
Windshield Wiper De-icer (Fig. 2) is available on NS
vehicles.
The Rear Window Defogger system consists of two
vertical bus bars linked by a series of grid lines on
the inside surface of the rear window. The electrical
circuit consists of the rear defogger switch in the
HVAC and a relay with timer switch to turn OFF the
system after ten minutes. The main feed circuit is
protected by fuse one (40 amp) in the Junction Block.
The rear defogger switch and relay also activates the
heated power side view mirrors and heated wind-
shield wiper de-icer. The HVAC rear defogger switch
is protected by fuse ten (10 amp) in the Junction
Block. The heated mirror circuit is protected by fuse
12 (10 amp) in the junction block. The heated wind-
shield wiper de-icer circuit is protected by fuse 21 (25
amp) in the Junction Block.
The Heated Windshield Wiper Deicer is also acti-
vated when the DEFROST mode is selected on the
HVAC. In the DEFROST mode the rear defogger
relay/timer is bypassed, the heated windshield wiper
de-icer will stay ON until the another mode is
selected. For circuit information and component loca-
tion refer to Group 8W, Wiring Diagrams.
CAUTION: Since grid lines can be damaged or
scraped off with sharp instruments, care should be
taken in cleaning the glass or removing foreign
materials, decals or stickers. Normal glass cleaning
solvents or hot water used with rags or toweling is
recommended.
HVAC MOUNTED SWITCH
The rear window defogger switch is integrated into
the HVAC (Fig. 3). An LED indicator will illuminate
when the switch is activated. The switch energizesthe timing circuit and activates the rear window
defogger relay. The relay controls the current to flow
to the grids of the rear window defogger, heated
power side view mirrors and the heated windshield
wiper de-icer. The defogger relay will be on for
approximately 10 minutes or until the control switch
or ignition is turned off.

DIAGNOSIS AND TESTING
SYSTEM TEST
Electrically heated rear window defogger or the
heated windshield wiper deicer operation can be
checked on the vehicle in the following manner:
(1) Turn the ignition switch to the ON position.
(2) Using a ammeter on the battery, turn the rear
defogger control switch to the ON position, a distinct
increase in amperage draw should be noted.
(3) The rear window defogger or the heated wind-
shield wiper deicer operation can be checked by feel-
ing the glass. A distinct difference in temperature
between the grid lines and adjacent clear glass can
be detected in 3 to 4 minutes of operation.
(4) Using a DC voltmeter (Fig. 4) contact terminal
B with the negative lead, and terminal A with the
positive lead. The voltmeter should read 10-14 volts.
(5) Indicator light illumination means that there is
power available at the switch only and does not nec-
essarily verify system operation.
(6) If turning the defogger switch ON, no distinct
current draw on the ammeter the problem should be
isolated in the following manner:
²Confirm that ignition switch is ON.
²Ensure that the heated rear window or the
heated windshield wiper deicer feed pigtail is con-
nected to the wiring harness and that the ground
pigtail is in fact grounded.
²Ensure that the proper fuse in the Junction
Block is OK.(7) When the above steps have been completed and
the system is still inoperative, one or more of the fol-
lowing is defective:
²HVAC switch
²Rear window defogger relay in the relay bank.
²Check for loose connector or a wire pushed out
of connector.
²Rear window or the windshield grid lines (all
grid lines would have to be broken, or one of the feed
pigtails not connected to the bus bar, for no ammeter
deflection).
(8) If turning the switch ON produces severe volt-
meter deflection, the circuit should be closely checked
for a shorting condition.
(9) If the system operation has been verified but
indicator LED does not light, replace switch.
(10) For detailed wiring information, refer to
Group 8W, Wiring Diagrams.
GRID LINE TEST
The horizontal grid lines and vertical bus bar lines
printed and baked on inside surface of the window
glass makes up an electrical parallel circuit. The
electrically conductive lines are composed of a silver
ceramic material which when baked on glass
becomes bonded to the glass and is highly resistant
to abrasion. It is possible, however, that a break may
exist or occur in an individual grid line resulting in
no current flow through the line. To detect breaks in
grid lines, the following procedure is required:
(1) Turn ignition and rear window defogger control
switch ON. The indicator light should come on.
(2) Using a DC voltmeter with 0-15 volt range,
contact vertical bus bar connecting grid lines on pas-
senger side of vehicle at terminal A with negative
lead of voltmeter (Fig. 4). With positive lead of volt-
meter, contact vertical bus bar on driver side of vehi-
cle at terminal B. The voltmeter should read 10-14
volts.

determine whether a valid key is in the ignition lock
cylinder.
The Smart Key transponder cannot be repaired
and, if faulty or damaged, it must be replaced.
SMART KEY IMMOBILIZER SYSTEM INDICATOR
LAMP
The Smart Key Immobilizer System (SKIS) indica-
tor lamp gives an indication when the SKIS is faulty
or when the vehicle has been immobilized due to the
use of an invalid ignition key. The lamp is controlled
by the instrument cluster circuitry based upon mes-
sages received from the Smart Key Immobilizer Mod-
ule (SKIM) on the Chrysler Collision Detection (CCD)
data bus.
The SKIM sends messages to the instrument clus-
ter to turn the lamp on for about three seconds when
the ignition switch is turned to the On position as a
bulb test. After completion of the bulb test, the SKIM
sends bus messages to keep the lamp off for a dura-
tion of about one second. Then the SKIM sends mes-
sages to the instrument cluster circuitry to turn the
lamp on or off based upon the results of the SKIS
self-tests. If the SKIS indicator lamp comes on and
stays on after the bulb test, it indicates that the
SKIM has detected a system malfunction and/or that
the SKIS has become inoperative. If the SKIM
detects an invalid key when the ignition switch is
turned to the On position, it sends messages to the
instrument cluster to flash the SKIS indicator lamp.
The SKIM can also send messages to the instru-
ment cluster to flash the lamp and to generate a sin-
gle audible chime tone. These functions serve as an
indication to the customer that the SKIS has been
placed in its ªCustomer Learnº programming mode.
See Smart Key Immobilizer System Transponder Pro-
gramming in this group for more information on the
ªCustomer Learnº programming mode.
The SKIS indicator lamp uses a replaceable incan-
descent bulb and bulb holder on the instrument clus-
ter electronic circuit board. Refer to Group 8E -
Instrument Panel Systems for diagnosis and service
of a faulty SKIS indicator lamp. If the SKIS indicator
lamp comes on and stays on after the bulb test func-
tion, diagnosis of the SKIS should be performed with
a DRB scan tool and the proper Diagnostic Proce-
dures manual.

The abbreviation T/O is used in the component
location section to indicate a point in which the wir-
ing harness branches out to a component.
ELECTROSTATIC DISCHARGE (ESD) SENSITIVE
DEVICES
All ESD sensitive components are solid state and a
symbol (Fig. 4) is used to indicate this. When han-
dling any component with this symbol comply with
the following procedures to reduce the possibility of
electrostatic charge build up on the body and inad-
vertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume
that it is.
(1) Always touch a known good ground before han-
dling the part. This should be repeated while han-
dling the part and more frequently after sliding
across a seat, sitting down from a standing position,
or walking a distance.
(2) Avoid touching electrical terminals of the part,
unless instructed to do so by a written procedure.(3) When using a voltmeter, be sure to connect the
ground lead first.
(4) Do not remove the part from its protective
packing until it is time to install the part.
(5) Before removing the part from its package,
ground the package to a known good ground on the
vehicle.
POSITIVE TEMPERATURE COEFFICIENT
Positive Temperature Coefficient (PTC) devices are
being used for circuit protection. These PTC's act like
a solid state fuse. They are located in the junction
block, and are used to protect such items as: power
door lock motors, power windows, and various engine
solenoids.
A special symbol is used to identify these in the
wiring diagrams (Fig. 5).
