GENERAL INFORMATION
WARNING: ON VEHICLES EQUIPPED WITH AIR
BAG, SEE GROUP 8M, RESTRAINT SYSTEMS FOR
AIR BAG REMOVAL PROCEDURES.
The turn signals are part of the multi-function
switch. Which contains:
• Electrical circuitry for turn signals
• Hazard warning switch
• Headlamp beam select switch
• Headlamp optical horn
• Windshield wiper switch
• Pulse wipe and windshield washer switching
The integrated switch assembly is mounted to the left
hand side of the steering column. When the driver
wishes to signal his intentions to change direction of
travel, he moves the lever upward to cause the right
signals to flash and downward to cause the left signals
to flash. After completion of a turn the system is deac-
tivated automatically. As the steering wheel returns to
the straight ahead position, a canceling cam molded to
the clockspring mechanism comes in contact with the
cancel actuator on the turn signal multi-function switch
assembly. The cam lobe, pushing on the cancel actuator,
returns the switch to the off position.
If only momentary signaling such as indication of a
lane change is desired, the switch is actuated to a
left or right intermediate detent position. In this po-
sition the signal lamps flash as described above, but
the switch returns to the OFF position as soon as the
lever is released.
When the system is activated, one of two indicator
lamps mounted in the instrument cluster flashes in
unison with the turn signal lamps, indicating to the
driver that the system is operating.
HAZARD WARNING SYSTEM
The hazard warning system is actuated by a push
button located on the top of the steering column be-
tween the steering wheel and the instrument panel. The
hazard switch is identified with a double triangle on top
of the button. Push and release the button to turn the
hazard function ON or OFF. The button will move out
from the steering column in the ON position and will
remain in toward the column in the OFF position.
MULTI-FUNCTION SWITCH TESTS
The multi-function switch contains electrical cir-
cuitry for turn signal, hazard warning, headlamp
beam select, headlamp optical horn, windshield
wiper, pulse wipe, and windshield washer switching.
This integrated switch assembly is mounted to the
left hand side of the steering column. Should any
function of the switch fail, the entire switch assem-
bly must be replaced. Refer to Fig. 1 for diagnosis.
To test the switch, first disconnect the negative
battery cable, then remove the upper and lower col-
umn covers to gain access to the switch connector.
Remove switch connector. Using an ohmmeter, test
for continuity (no resistance) between the terminals
of the switch as shown in the following continuity
charts (Fig 2 or 3).
MULTI-FUNCTION SWITCH REPLACEMENT
(1) Disconnect battery negative cable.
(2) Remove tilt lever.
(3) Remove both upper and lower steering column
shrouds.
(4) Remove multi-function switch mounting screws
(Fig.4).
(5) For installation, reverse above procedure.
(a) Tighten multi-function switch to column re-
taining screws to 2 NIm (17 in. lbs.) torque.
(b) Tighten steering column cover retaining
screws to 2 NI (17 in. lbs.) torque.
TURN SIGNAL AND HAZARD WARNING FLASHER
LOCATION
The turn signal flasher and the hazard warning
flasher are combined into one unit called a combina-
tion flasher (combo-flasher). The combo-flasher con-
trols the flashing of the hazard warning system and
the turn signal system. An inoperative bulb or in-
complete turn signal circuit will result in an increase
in flasher speed.
The combo-flasher is mounted to the in-line
bracket which is located to the of the junction block.
The flasher can be removed by pulling in an rear-
ward direction. The left under panel silencer duct
must be removed to access the flasher. The combo-
flasher is black in color for ease of identification (Fig.
5).
