DESCRIPTION
Fig. 2 Multi-Function Switch
1 – WINDSHIELD WASHER BUTTON
2 – CONTROL STALK (BEAM SELECT)
3 – HAZARD WARNING BUTTON
4 – MULTI-FUNCTION SWITCH
5 – WINDSHIELD WIPER CONTROL
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.
OPERATION
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 deactivated automatically. As the
steering wheel returns to the straight ahead position,
a canceling cam molded to the clockspring mecha-
nism 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
position 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.
DIAGNOSIS AND TESTING

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.
Refer to Group 8K, Windshield Wiper and Washer
Systems for Wiper and Washer functions. This inte-
grated switch assembly is mounted to the left hand
side of the steering column. Should any function of
the switch fail, the entire switch assembly must be
replaced. Refer to Combination Flasher Diagnosis
table.
To test the switch, the switch must first be
removed. Refer to Multi-function Switch Removal
and Installation procedures within this section.
Using an ohmmeter, test for continuity (no resis-
tance) between the terminals of the switch as shown
in the Turn Signal and Hazard Switch Continuity
and Beam Select Switch Continuity tables.
