GENERAL INFORMATION
INTRODUCTION
The turn signals are actuated with a lever on the
left side of the steering column just ahead of the
steering wheel. The signals are automatically turned
off by a canceling cam (two lobes molded to the clock-
spring mechanism). The cam comes in contact with
the cancel actuator on the turn signal (multi-func-
tion) switch assembly. Either cam lobe, pushing on
the cancel actuator, returns the switch to the OFF
position.
Lane change signaling is actuated by applying par-
tial turn signal stalk movement toward the direction
desired until the indicator lamps flashes in the
instrument cluster. When the switch stalk is released
the stalk will spring back into the neutral position
turning OFF the turn signal.
With the ignition switch ON and the turn signal
switch stalk actuated left or right, current flows
through the:
²Combination flasher
²Multi-function switch
²Turn indicator lamp
²Front and rear turn signal bulbs.
A chime will sound after the vehicle has traveled a
distance of approximately 0.5 mile with the turn sig-
nal ON.
COMBINATION FLASHER
The Turn Signal/Hazard Warning Flasher is a
module providing the vehicle with turn signal and
hazard warning functions and has been designed
with internal relays to take advantage of low current
switching requirements in the vehicle. It is plugged
into the Junction Block at position 4 (Fig. 1), where
all wiring associated with its operation is terminated.The Junction Block is adjacent to and left of the
steering column of the vehicle.
To gain access to the flasher, remove the lower
steering column cover and knee blocker. Refer to
Group 8E, Instrument Panel and Systems for
removal procedures.
DESCRIPTION AND OPERATION
COMBINATION FLASHER FUNCTION
The Turn Signal/Hazard Warning Flasher is a
module providing turn signal, hazard warning func-
tions and has been designed with internal relays to
Fig. 1 Combination Flasher Location
NSTURN SIGNAL AND FLASHERS 8J - 1

take advantage of low current switching require-
ments in the vehicle. It is plugged into the Junction
Block at positions 4 (Fig. 1) where all wiring associ-
ated with its operation is terminated. The Junction
Block is adjacent to and left of the steering column of
the vehicle.
To gain access to the device, remove the lower
steering column cover and knee blocker, refer to
Group 8E, Instrument Panel and Systems.
The combination flasher may be operated in its
hazard warning mode either with or without the igni-
tion circuit being active. However, in order to operate
in the turn signal mode, the ignition circuit must be
completed to the module.
While the combination flasher is idle, there is no
current drawn through the module. The device does
not become active until a signal ground circuit is
supplied to either of the turn signal inputs or the
hazard warning input.
Typical flash rate for the flasher is 90 flashes per
minute.
When a lamp is burnt out for a given side of the
vehicle or a wire is open to a lamp, the flash rate will
increase to 180 flashes per minute when in the turn
signal mode. When in the hazard warning signal
mode the flash rate remains at 90 flashes per
minute.
Turn signal inputs that actuate the flasher are low
current grounds, each drawing a maximum of 300
mA., and are provided to the flasher through the
Junction Block from the multi-function switch that is
mounted to the steering column. The hazard warning
signal input is a low current ground drawing a max-
imum of 600 mA. through the multi-function switch.
COMBINATION FLASHER / DAYTIME RUNNING
LAMPS (DRL) MODULE
The Combination Flasher/DRL is a module provid-
ing turn signal, hazard warning, and daytime run-
ning light functions, and has been designed with
internal relays to take advantage of low current
switching requirements in the vehicle. It is plugged
into the junction block at positions 3 AND 4 (Fig. 2)
where all wiring associated with its operation is ter-
minated. The Junction Block is adjacent to and left of
the steering column of the vehicle.
To gain access to the device, remove the lower
steering column cover and knee blocker, refer to
Group 8E, Instrument Panel and Gauges.
The combination flasher/DRL may be operated in
its hazard warning mode either with or without the
ignition circuit being active. However, in order to
operate in the turn signal mode or the DRL mode,
the ignition circuit must be completed to the module.
While the combination flasher portion is idle, there
is no current drawn through the module. The devicedoes not become active in the turn signal or hazard
warning modes until a signal ground circuit is sup-
plied to either of the turn signal inputs or the hazard
warning input. With the ignition OFF, there is no
current drawn through the module.
While the ignition is ON, the front turn signal fil-
aments are illuminated steadily thus providing the
DRL function. The DRL function may be inhibited by
applying a signal ground input from either the park
brake circuit or the headlamp relay activation circuit.
Typical flash rate for the flasher is 90 flashes per
minute.
When a lamp is burnt out for a given side of the
vehicle or a wire is open to a lamp, the flash rate will
increase to 180 flashes per minute when in the turn
signal mode. When in the hazard warning signal
mode the flash rate remains at 90 flashes per
minute.
Turn signal inputs that actuate the flasher are low
current grounds, each could draw a maximum of 300
mA., and are provided to the flasher through the
Junction Block from the multi-function switch that is
mounted to the steering column. The hazard warning
signal input is a low current ground that could draw
a maximum of 600 mA. through the multi-function
switch.

The windshield wipers can be operated with the
windshield wiper switch when the ignition switch is
in the RUN or ACCESSORY positions. The wind-
shield wiper system is protected by a 40 amp fuse (9)
located in the Power Distribution Center (PDC) in
the engine compartment. The windshield washer cir-
cuit is protected by a 6 amp fuse (9) located in the
Junction Block. The wiper motor has permanent
magnetic fields. The speeds are determined by cur-
rent flow to the appropriate set of brushes inside the
motor. The current flow is controlled by the multi-
function switch stalk mounted wiper switch, high
speed/low speed relays located in the PDC. The speed
sensitive intermittent wiper is controlled by the BodyControl Module (BCM). The intermittent mode, with
the vehicle traveling greater than 10.4 mph, has a
range of 0.5 to 18 seconds. With the vehicle traveling
less than 10.4 mph, and the time delay is not
adjusted, time delay doubles to a range of 1 to 36
seconds. The wiper arms will park at the base of the
windshield just above the cowl cover after the wiper
switch is turned OFF.
The windshield wiper motor and linkage is located
in an integral wiper unit at the rear of the engine
compartment. The wiper unit must be removed to
gain access to the wiper motor.
