DESCRIPTION AND OPERATION

MULTI-FUNCTION SWITCH

WARNING: VEHICLES ARE EQUIPPED WITH AN
AIRBAG,

REFER

TO

GROUP

8M,

PASSIVE

RESTRAINT SYSTEMS FOR STEERING WHEEL OR
COLUMN SERVICE PROCEDURES.

DESCRIPTION

The multi-function switch 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.

OPERATION

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. Intermit-
tent wiper operation is controlled by the Body Con-
trol 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 cir-
cuitry. The wiper motor also has an internal non-ser-
viceable 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 intermit-
tent 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
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 elec-
tro-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

DESCRIPTION

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-func-
tion wiper control switch.

OPERATION

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 cur-
rent wipe cycle. Followed by an average of two more
wipe cycles (

61) before the wipers park and the mod-

ule 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 hoses to the hood mounted nozzles
which direct the fluid streams to the windshield. The
nozzles have one-way check valves located in the noz-
zle assemblies. 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 reser-
voir are serviced as separate assemblies.

WIPER BLADES

DESCRIPTION

The wiper blades are a rubber element with a steel

vertebrae that are mounted on the end of the wind-
shield wiper arm and sweep across the front wind-
shield to clear it of water, snow, and debris.

DESCRIPTION AND OPERATION (Continued)

OPERATION

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 ele-
ments are 550 mm in length.

DIAGNOSIS AND TESTING

MULTI-FUNCTION SWITCH – WINDSHIELD
WIPER

To test the multi-function windshield wiper switch,

refer to Group 8J Turn Signals and Hazard Warning
Flashers, for diagnosis and testing of the Multi-Func-
tion Switch.

WINDSHIELD WASHERS

Whenever a windshield washer malfunction occurs,

first verify that the windshield washer wire harness
is properly connected to all connectors before starting
normal diagnosis and repair procedures. Refer to
Windshield Washer Test table.

WINDSHIELD WIPER SYSTEM CONDITIONS

The following is a list of general wiper motor sys-

tem 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.

(5) The wiper switch in the ON position. Using an

voltmeter, check for battery voltage at terminal 29 of
the intermittent wiper relay in the Power Distribu-
tion Center. If no voltage check fuse 18 (Fig. 4). If
OK, go to Step 6. If not repair as necessary.

(6) Using an ohmmeter, check from terminal 28 of

the HI-LO wiper relay to Pin A of the motor wire
connector for continuity. Check from terminal 11 of
the HI-LO wiper relay to Pin B of the motor wire
connector for continuity. If OK, go to Step 7. If not
repair as necessary.

(7) Using

an

ohmmeter,

check

for

continuity

between the HI-LO wiper relay and the intermittent
wiper relay. Check from terminal 36 of the HI- LO
wiper relay to terminal 37 of the intermittent wiper
relay. If OK, check for faulty relays. If not repair as
necessary.

(8) Disconnect the J3 14-way connector from the

BCM (Fig. 6).

(9) Using an ohmmeter, check for continuity from

terminal 7 of the J3 14-way connector to the terminal
15 of the intermittent wiper relay. If OK, go to Step
10. If not repair as necessary.
