GENERAL INFORMATION
MULTI-FUNCTION SWITCH
WARNING: VEHICLES ARE EQUIPPED WITH AN
AIRBAG, REFER TO GROUP 8M, RESTRAINT SYS-
TEMS FOR STEERING WHEEL OR COLUMN SERVICE PROCEDURES.
The multi-function switch (Fig. 1) contains:
• Turn signals
• Hazard warning
• Headlamps
• Headlamp beam select
• Parking lamps
• Panel dimmer
• Fog Lamp
• Headlamp optical horn
• Windshield wiper
• Pulse wipe
• Mist wipe
• Windshield washer switches.
The multi-function switch is mounted center of the
steering column. There are two levers, one on each
side of the steering column. The left side controls the
signaling and lighting. The right side controls the
windshield wiper and washer system. To use the
washers pull lever toward the driver. The mist is a
single wipe operation by pushing lever down and
releasing the lever. Intermittent wiper operation is

controlled by the Body Control Module (BCM). The
lever has a selection of delay intervals and by turning the lever the wiper will cycle every half second to
36 seconds depending ON the vehicle’s speed. The
wiper has two cycle two speeds.
The windshield wipers will only operate when the
ignition switch is in the ACCESSORY or IGNITION
RUN position. Fuse 15, located in the Junction Block,
fuses 8 and 14 in the Power Distribution Center
(PDC) block, protects the wiper/washer system circuitry. The wiper motor also has an internal non-serviceable circuit breaker to provide protection against
motor stall conditions.
The wiper and washer motors have magnetic fields
created by internal permanent magnet. Electric
power applied to the motor armature, located in the
magnetic field, causes the motor to turn.
The wiper system internal operation uses the low
speed motor circuit in combination with intermittent
wipe relay. The washer pump motor has one internal
circuit and therefore operates at one speed.
The wiper and washer system switch located on
the steering column selects the mode of operation of
the motors. The switch provides input to the BCM,
which in turn operates the two relays. The intermittent wipe relay turns the wiper ON and OFF. The
other changes the HIGH/LOW speeds. The switch
also provides power to the washer pump motor.
The intermittent wiper system, in addition to low
and high speed, has a delay mode. The delay mode
Page 2

GENERAL INFORMATION (Continued)
Fig. 1 Multi-Function Switch
has a range of 1/2 to 18 seconds when the vehicle
speed is over 10 m.p.h.. The wiper delay times will
automatically double to a range of 1 to 36 seconds
when the vehicle speed is less than 10 m.p.h.. The
delay is controlled by a variable resistor in the wiper
switch and BCM.
The wiper motor and washer motor are designed to
reduce radio frequency interference and provide electro-magnetic compatibility (RFI/EMC) in the vehicle
environment. This is done with suppression circuits
designed into the motors.
The wiper system completes the wipe cycle when
the switch is turned OFF. The blades park in the
lowest portion of the wipe pattern.
When using a scan tool (DRB) refer to the Body
Diagnostic Manual for the procedures.
WINDSHIELD WASHERS
All models are equipped with electric operated
windshield washer pumps. The wash function can be
accessed in the OFF or ON position of the multi-function wiper control switch.
DESCRIPTION AND OPERATION
WINDSHIELD WASHERS
Pulling the lever towards the driver when the
wiper switch is in the OFF position will operate the
wipers and washer motor pump continuously until
the lever is released. Releasing the lever will stop the
washer pump but the wipers will complete the current wipe cycle. Followed by an average of two more
wipe cycles (61) before the wipers park and the module turns off.
The electric pump assembly is mounted with a
grommet directly to the reservoir. Fluid is gravity fed
from the reservoir to the motor. The fluid is forced by
the pump through rubber hoses to the hood mounted
nozzles which direct the fluid streams to the windshield. The hose assembly has two one way flow
check valves located just before each hood nozzle.
The purpose of the check valves is to improve fluid
flow response time and to prevent excessive washer
fluid staining the surface of the hood. The hood
mounted nozzles evenly distribute washer fluid
across the surface of the windshield. The nozzles are
not adjustable. The pump and reservoir are serviced
as separate assemblies.
WIPER BLADES
When the wiper blade rubber element is exposed to
the weather for a long period of time, it tends to lose
wiping ability. Periodic cleaning of the wiper blade
element is suggested to remove the accumulation of
salt and road film. The wiper blades, arms, and
windshield should be cleaned with a sponge or cloth
and a mild detergent or non-abrasive cleaner. If the
blades continue to streak or smear, they should be
replaced. The driver and the passenger blade elements are 550 mm in length. Only the driver’s side
wiper blade has a air foil on it (Fig. 2).

WINDSHIELD WIPER SYSTEM CONDITIONS
The following is a list of general wiper motor system problems and tests that are to be performed to
locate the faulty part, and the corrective action to be
taken. These tests will cover both two speed and
intermittent wiper functions.
Actuation of the wiper relays can be performed
using ACTUATOR TESTS on the DRB lll. Status of
the wiper pardk switch can also be monitored.
MOTOR WILL NOT RUN IN ANY SWITCH POSITION
(1) Check fuse 15, in the Junction Block and fuse 8
and 18 in the Power Distribution Center (Fig. 3) and
(Fig. 4). Refer to Group 8W, Wiring Diagrams for pin
call outs.
(a) If fuse(s) are OK, go to Step 2.
(b) If fuse(s) are defective, replace and check
motor operation in all switch positions.
(c) If motor is still inoperative and the fuse does
not blow, go to Step 2.
(d) If replacement fuse blows, go to Step 11.
(2) Disconnect motor wire harness connector.
(3) Check the wiper motor low speed. Using two
jumper wires, connect one jumper wire between the
battery positive jump start terminal and Pin B on
the wiper motor connector (Fig. 5). Connect the other
jumper wire to ground and Pin C on the wiper motor
connector. Check the wiper motor high speed, connect
the positive jumper wire to Pin A on the wiper motor
connector. Connect the negative jumper wire to Pin C
on the wiper motor connector.
(a) If motor runs, go to Step 4.
(b) If motor does not run, high or low speed
replace the wiper motor.
(4) Using a ohmmeter, check for good ground at
Pin C of the wiper motor wire harness connector. If
OK, replace motor. If not repair the ground circuit as
necessary.

CLEANING AND INSPECTION
WIPER BLADES
Wiper blades exposed to the weather for a long
period of time tend to lose their wiping effectiveness.
Periodic cleaning of the wiper blade is recommended
to remove the accumulation of salt and road grime.
The wiper blades, arms and windshield should be
cleaned with a sponge or cloth and a mild detergent
or nonabrasive cleaner. If the wiper blades continue
to streak or smear, they should be replaced. The
wiper blade should run smoothly across the windshield in both directions. The wiper blade should
slightly roll over center when the blade reverses
direction. A wiper blade insert that has lost flexibility
or a wiper arm that has lost spring tension, will
cause the blade to skip or chatter across the windshield. If the wiper blades are new and the wiper
arm spring tension is OK and a chattering sound is
emitted from the wiper(s), the wiper blade is not rolling over center. If this condition exists, refer to the
Wiper Arm Alignment paragraph of this group.
ADJUSTMENTS
WIPER ARM
High speed, wet windshield operation, the right
blade tip may override the cowl screen slightly. This
is normal and should not affect wiper system performance.
(1) Lift arms and blade assemble to a over centered position.
(2) Turn ignition switch to ON or ACC position.
(3) Use LOW speed setting and cycle the wiper
motor to the PARK position.
(4) Turn ignition OFF.

GENERAL INFORMATION
INTRODUCTION
Headlamp washers are available as a factory-installed option on this model. The headlamp washers
on this vehicle work in conjunction with the windshield washers. The headlamp washers are enabled
with the headlamps “ON” and the windshield wash-
ers activated. With the windshield washers activated
the headlamp washers will spray for a preset amount
of time controlled by a relay.
The headlamp washer system utilizes a separate
pump that is attached to the windshield washer reservoir. The headlamp washer pump feeds two nozzles
that are mounted in the front fascia of the vehicle.
These nozzles spray the headlamps when the system
is activated.
