circuits, remember that high generator output can
burn out bulbs rapidly and repeatedly. If this is a
problem on the vehicle being diagnosed, refer to
Group 8A - Battery/Starting/Charging Systems Diag-
nostics to test charging system.
WARNING: ON VEHICLES EQUIPPED WITH AN AIR-
BAG, REFER TO GROUP 8M - RESTRAINT SYS-
TEMS BEFORE ATTEMPTING STEERING WHEEL

(1) Turn ignition switch to ON position. Actuate the
turn signal lever or hazard warning button. Observe
the turn indicator lamp(s) in the instrument cluster.
If the flash rate is very high, check for a turn signal
bulb that is not lit. Replace that bulb or repair cir-
cuits to that lamp, as required. Test operation. If turn
indicator does not light, continue to next step.
(2) Remove and inspect fuse 8 (turn signals) in
fuseblock module, or fuse F13 (hazard warning) in the
Power Distribution Center. Replace fuse, if required.
(3) Remove combination flasher from relay center
and replace with a known good unit. Test operation of
turn signal and hazard warning systems. If OK, re-place faulty combination flasher. If not OK, remove
test flasher and go to next step.

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.

termittent 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 switch and is accomplished by electronic cir-
cuitry within the intermittent wipe module. If the
washer knob is depressed while the wiper switch is
in the OFF position, the intermittent wipe module
will operate the wiper motor for approximately 2
wipes and automatically turn the motor off.
The intermittent wipe module is mounted to a
bracket behind the lower instrument panel, near the
steering column with a hook and loop fastener patch.
The module can not be repaired.
WINDSHIELD WASHER NOZZLES
The two fluidic washer nozzles are screwed into
openings in the cowl panel below the windshield and
are not adjustable. Washer fluid is fed to the nozzles
through hoses underneath the cowl panel. The noz-
zles can not be repaired and, if faulty, should be re-
placed.
LIFTGATE WASHER NOZZLE
The single liftgate washer nozzle is installed
through the liftgate glass and secured with a nut on
the inside of the glass. Washer fluid is fed to the noz-
zle from the washer reservoir in the engine compart-
ment. 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 nozzle
can not be repaired and, if faulty, should be replaced.
