Chrysler 300M, Dodge Interpid. Manual — part 91

• 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.

HAZARD WARNING SYSTEM

The hazard warning system is actuated by a push

button located on the top of the steering column
between the steering wheel and the instrument panel
(Fig. 39). The hazard switch is identified with a dou-
ble triangle on top of the button.

OPERATION

MULTI-FUNCTION SWITCH

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 clock spring 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.

HAZARD WARNING SYSTEM

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.

DIAGNOSIS AND TESTING - MULTI-FUNCTION
SWITCH

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 Electrical, Wipers/Washers, Description and
Operation 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 the COMBINATION FLASHER
DIAGNOSIS table.

To test the switch, the switch must first be

removed. Refer to Multi-function Switch Removal
and Installation. Using an ohmmeter, test for conti-
nuity (no resistance) between the terminals of the
switch as shown in the TURN SIGNAL AND HAZ-
ARD SWITCH CONTINUITY table, BEAM SELECT
SWITCH CONTINUITY table, (Fig. 40), and (Fig.
41).
