HEADLAMP HIGH BEAM INDICATOR LAMP
The high beam indicator lamp is controlled by the
headlamp dimmer (multi-function) switch. One side
of the indicator bulb is grounded at all times. The
other side of the bulb receives battery feed through
the contacts of the dimmer switch when the multi-
function switch stalk is actuated to turn the head-
lamp high beams on. Refer to Group 8L - Lamps for
more information.
LOW FUEL WARNING LAMP
A Light-Emitting Diode (LED) on the face of the
fuel gauge will light when the fuel level falls below
approximately 4 gallons. A low fuel warning module
attached to the rear of the fuel gauge controls when
the LED will light. When the module senses 66.5
ohms or more resistance from the fuel level sending
unit for 10 continuous seconds, the LED will light.
When the module senses 63.5 ohms or less resistance
from the fuel level sending unit for 20 continuous
seconds, the LED is turned off.
LOW OIL PRESSURE WARNING LAMP
The low oil pressure warning lamp lights with the
ignition switch in the ON position and the engine not
running. The lamp should be off when the engine is
running. Battery voltage is supplied to one side of
the indicator bulb when the ignition switch is turned
ON. The warning lamp side of the combination oil
pressure sending unit is connected to the other side
of the bulb. When normal engine oil pressure is ap-
plied to the sending unit, resistance on the warning
lamp side is high and the lamp goes off. When engine
oil pressure is too low, resistance on the warning
lamp side of the sending unit is low, which causes
the bulb to light.
LOW WASHER FLUID WARNING LAMP
The low washer fluid warning lamp indicates when
the fluid level in the washer reservoir is too low. The
washer fluid level sensor uses a float in the reservoir
to monitor fluid level. The action of the float opens or
closes the switch within the sensor that provides ig-
nition-switched battery voltage to the lamp bulb. Re-
fer to Group 8K - Wiper and Washer Systems for
more information.
MALFUNCTION INDICATOR LAMP
The CHECK ENGINE or Malfunction Indicator
Lamp (MIL) lights each time the ignition switch is
turned ON, and stays on for 3 seconds as a bulb test.
If the Powertrain Control Module (PCM) receives an
incorrect signal or no signal from certain fuel oremission system related circuits or components, the
lamp is turned on. This will indicate that the PCM
has recorded a Diagnostic Trouble Code (DTC) in
electronic memory for a circuit or component mal-
function. Refer to Group 14 - Fuel System for more
information.
SEAT BELT REMINDER LAMP
The seat belt reminder lamp lights for 4 to 8 sec-
onds after the ignition switch is turned to the ON po-
sition. A timer in the chime/buzzer module controls
ignition-switched battery feed to the lamp. Refer to
Group 8U - Chime/Buzzer Warning Systems for more
information.
TURN SIGNAL INDICATOR LAMPS
The left and right turn signal indicator lamps are
controlled by the turn signal and hazard warning
(multi-function) switches. One side of the bulb for
each lamp is grounded at all times. The other side of
the bulb receives battery feed through the contacts of
the multi-function switch when the turn signal lever
(multi-function switch stalk) or hazard warning but-
ton are actuated. Refer to Group 8J - Turn Signal
and Hazard Warning Systems for more information.
UPSHIFT INDICATOR LAMP
Vehicles equipped with manual transmissions have
an optional upshift indicator lamp. Ground feed for
the lamp is switched by the Powertrain Control Mod-
ule (PCM). The lamp lights to indicate when the
driver should shift to the next highest gear for best
fuel economy. The PCM will turn the lamp off after 3
to 5 seconds if the upshift is not performed. The lamp
will remain off until the vehicle stops accelerating
and is brought back to the range of lamp operation,
or until the transmission is shifted into another gear.
The indicator lamp is normally on when the igni-
tion switch is turned ON and is turned off when the
engine is started. The lamp will be turned on during
vehicle operation according to engine speed and load.
CLUSTER ILLUMINATION LAMPS
All cluster illumination lamps receive battery feed
from the instrument lamps fuse in the fuseblock
module through the panel dimmer rheostat of the
headlamp switch. When the park or headlamps are
on, the cluster illumination lamps light. Illumination
brightness can be adjusted by rotating the headlamp
switch knob (clockwise to dim, counterclockwise to
brighten).
8E - 4 INSTRUMENT PANEL AND GAUGESÐXJJ

The two pivot cranks are joined by a connecting link,
and a drive link connects the motor crank to the drive
link near the left pivot. Pressed-in plastic bushings in
the ends of the links can be replaced if worn or dam-
aged.
WINDSHIELD WIPER MOTOR
The two-speed permanent magnet wiper motor has
an integral transmission and park switch. The motor
is mounted to the engine side of the cowl panel with
a reinforcement/stud plate and a rubber-isolated
mounting bracket. The wiper motor output shaft
passes through the cowl panel into the cowl plenum
area, where a crank arm attached to the output shaft
drives the wiper drive link.
Wiper speed is controlled by current flow to the ap-
propriate set of brushes. The wiper motor completes
its wipe cycle when the switch is turned OFF, and
parks the blades in the lowest portion of the wipe
pattern. The wiper motor assembly can not be re-
paired. If faulty, the entire motor assembly must be
replaced. The crank arm, mounting bracket, and re-
inforcement/stud plate are available for service.
LIFTGATE WIPER MOTOR
The liftgate wiper motor contains integral elec-
tronic controls and a transmission to provide three
operating modes:
²intermittent wipe with a fixed 5 to 8 second delay
between wipes
²constant wipe that operates when the liftgate
washer is operated
²a park mode that runs the motor until the wiper
blade reaches the park position after the liftgate
wiper switch or ignition switch is turned OFF.
The liftgate wiper motor can not be repaired. If
faulty, the entire assembly must be replaced.
WINDSHIELD WIPER/WASHER SWITCH
Controls for the windshield wiper and washer sys-
tems are contained in the multi-function switch con-
trol lever. The multi-function switch is mounted on
the left side of the steering column between the
steering wheel and the instrument panel. This switch
also controls many other functions. The multi-func-
tion switch can not be repaired. If any function of the
switch is faulty, the entire switch must be replaced.
LIFTGATE WIPER/WASHER SWITCH
The single two-function switch on the instrument
panel right of the steering column controls the lift-
gate wiper and washer functions. The rocker-type
switch features a detent in the WIPE position, but
only momentary contact in the WASH position. Both
the liftgate wiper and liftgate washer motors will op-
erate continuously for as long as the switch is held in
the WASH position. The switch can not be repaired;
if faulty, it must be replaced.
INTERMITTENT WIPE MODULE
In addition to low and high speed, the optional inter-
mittent wipe system has a delay mode. The delay mode
has a range of 2 to 15 seconds. The length of the delay
is selected with a variable resistor in the wiper (multi-
function) switch and is accomplished by electronic cir-
cuitry within the intermittent wipe module. If the
washer knob is depressed while the wiper (multi-func-
tion) switch is in the OFF position, the intermittent
wipe module will operate the wiper motor for approxi-
mately 2 wipes and automatically turn the motor off.
The intermittent wipe module is mounted to the
lower instrument panel, behind the knee blocker and
near the steering column with a hook and loop fas-
tener patch. The module can not be repaired.
WINDSHIELD WASHER NOZZLES
The two fluidic washer nozzles are riveted into
openings in the cowl grille panel below the wind-
shield and are not adjustable. Washer fluid is fed to
the nozzles through hoses clipped to the underside of
the cowl grille panel. The nozzles can not be repaired
and, if faulty, should be replaced.
LIFTGATE WASHER NOZZLE
The single liftgate washer nozzle snaps into place
on the liftgate wiper arm. Washer fluid is fed to the
nozzle from the washer reservoir in the engine com-
partment. A liftgate washer hose system is routed
through the body of the vehicle with the body wiring
harness from the reservoir to the liftgate. The fluid
passes through a nipple on the liftgate wiper motor
output shaft bezel to a hose clipped to the underside
of the wiper arm. The nozzle can not be repaired and,
if faulty, should be replaced.
WASHER RESERVOIR
The washer solvent reservoir is mounted to the left
front inner fender shield near the cowl panel. The
same reservoir is used for both the standard front
and optional liftgate washer systems. It also has a
provision for a low washer fluid level sensor. Refer to
Group 8E - Instrument Panel and Gauges for diagno-
sis and service of the sensor. The reservoir and filler
cap are available for service.
WASHER PUMPS
The washer pump and motor are press-fit into a
rubber grommet near the bottom of the washer res-
ervoir. Vehicles with the optional liftgate wiper/
washer system have two pumps installed in the
single reservoir. A permanently lubricated and sealed
motor is coupled to a rotor-type pump. Washer fluid
is gravity fed from the reservoir to the pump. The
pump then pressurizes the fluid and forces it through
the plumbing to the nozzles when the motor is ener-
gized. The pump and motor can not be repaired. If
faulty, the entire assembly must be replaced.

WIPERSÐSTANDARD
A circuit breaker powers the standard wiper sys-
tem. The standard wiper system operates at either
LOW or HIGH speeds.
In the ACCESSORY or RUN position, the ignition
switch connects circuit A1 from fuse 6 in the Power
Distribution Center (PDC) with circuit A48. Circuit
A48 supplies voltage to circuit F86 through the circuit
breaker near the left kick panel.
Circuit F86 is double crimped at the circuit breaker
and supplies power to the wiper switch and the park
switch in the wiper motor. Circuit Z1 from the wiper
motor provides ground for the wiper motor and
switch.
When the operator moves the wiper switch to the
LOW position, battery voltage passes through the
switch to circuit V3. Circuit V3 feeds the wiper motor
low speed brushes. If the operator selects wiper
HIGH speed operation, the wiper switch passes cur-
rent to circuit V4. Circuit V4 feeds the wiper motor
high speed brushes.
As the windshield wiper motor turns, the park
switch, internal to the motor, moves from its DOWN
position to the UP position. When the wiper switch is
turned OFF, the V55 circuit prevents the wipers from
stopping in any position but park.
The windshield washer uses a pump motor located
inside the windshield washer fluid reservoir. When
the washer switch is pressed, power is supplied
through the wiper switch to the pump motor on cir-
cuit V10. Circuit Z1 provide ground for the pump
motor.
HELPFUL INFORMATION
Circuit Z1 also provides ground for the rear wiper
washer pump, radiator fan motor and front end light-
ing.
WIPERSÐINTERMITTENT
A circuit breaker powers the standard wiper sys-
tem. The intermittent wiper system operates at either
LOW or HIGH or DELAY speeds.
In the ACCESSORY or RUN position, the ignition
switch connects circuit A1 from fuse 6 in the PDC
with circuit A48. Circuit A48 supplies voltage to cir-
cuit F86 through the circuit breaker near the left kick
panel.Circuit F86 is double crimped at the circuit breaker
and supplies power to the wiper switch and the park
switch in the wiper motor. Circuit Z1 from the wiper
motor provides ground for the wiper motor and
switch.
When the operator moves the wiper switch to the
LOW position, battery voltage passes through the
switch to circuit V3. Circuit V3 feeds the wiper motor
low speed brushes. If the operator selects wiper
HIGH speed operation, the wiper switch passes cur-
rent to circuit V4. Circuit V4 feeds the wiper motor
high speed brushes.
The DELAY portion of the wiper switch contains a
variable resistor. The variable resistor connects to the
intermittent wiper module through the wiper switch
harness. The amount of delay selected by the operator
determines the voltage drop through the resistor and
the voltage level received by the intermittent wiper
module.
After the intermittent wiper control module deter-
mines the amount of delay selected, it cycles the
wipers by periodically energizing circuit V3. Circuit
V3 powers the wiper motor low speed brushes.
As the windshield wiper motor turns, the park
switch, internal to the motor, moves from its DOWN
position to the UP position. When the wiper switch is
turned OFF, the V55 circuit prevents the wipers from
stopping in any position but park.
The windshield washer uses a pump motor located
inside the windshield washer fluid reservoir. When
the washer switch is pressed, power is supplied
through the wiper switch to the pump motor on cir-
cuit V10. Circuit Z1 provides ground for the pump
motor.
HELPFUL INFORMATION
Circuit Z1 also provides ground for the rear wiper
washer pump, radiator fan motor and front end light-
ing.
REAR WIPER SYSTEM
In the RUN position, the ignition switch connects
circuit A1 from fuse 6 in the PDC with circuit A38.
Circuit A38 connects to a fuse block bus bar that
powers circuit V15 through the fuse in cavity 1. Cir-
cuit V15 supplies power to the rear wiper switch.
J8W-53 WIPERSÐXJ VEHICLES 8W - 53 - 1

In the WIPE or WASH positions, the rear wiper
switch supplies voltage to the wiper motor on circuit
V13. Circuit Z1 provides ground for the wiper motor.
The rear windshield washer uses a pump motor lo-
cated inside the windshield washer fluid reservoir.
When the rear wiper switch is pressed, power is sup-
plied through the wiper switch to both the rear wiper
and the pump motor on circuit V20. Circuit Z1 pro-
vides ground for the pump motor.
As the rear wiper motor turns, the park switch, in-
ternal to the motor, moves from the RUN position to
the PARK position. When the wiper switch is turned
OFF, the F20 circuit prevents the wipers from stop-
ping in any position but park.DIAGRAM INDEX
