safety equipment on this model. The turn signal sys-
tem uses ignition switched battery current, and will
operate only when the ignition switch is in the On or
Accessory positions. The turn signal system includes
the following components:

• Combination flasher

• Turn signal cancelling cam

• Turn signal indicator lamps

• Turn signal lamps

• Turn signal switch.
Refer to Lamp in the proper section of Group 8L -

Lamps for more information on the exterior turn sig-
nal lamps. Refer to Instrument Cluster in the
proper section of Group 8E - Instrument Panel Sys-
tems for more information on the turn signal indica-
tor lamps. Following are general descriptions of the
major components in the turn signal system. For
complete circuit diagrams, refer to Turn Signals in
the Contents of Group 8W - Wiring Diagrams.

OPERATION

With the ignition switch in the On or Accessory

position, and the turn signal (multi-function) switch
control stalk moved up (right turn) or down (left
turn), the turn signal system is activated. When the
turn signal system is activated, the circuitry of the
turn signal switch and the combination flasher will
cause the selected (right or left) turn signal indicator
lamp, front park/turn signal lamp, and rear tail/stop/
turn signal lamp to flash on and off in unison.

See the owner’s manual in the vehicle glove box for

more information on the features, use and operation
of the turn signal system.

HAZARD WARNING SYSTEM

DESCRIPTION

A hazard warning system is standard factory-in-

stalled safety equipment on this model. Unlike the
turn signal system, the hazard warning system uses
a non-switched source of battery current so that the
system will operate regardless of the ignition switch
position. The hazard warning system includes the fol-
lowing components:

• Combination flasher

• Hazard warning switch

• Turn signal indicator lamps

• Turn signal lamps.
Refer to Lamp in the proper section of Group 8L -

Lamps for more information on the exterior turn sig-
nal lamps. Refer to Instrument Cluster in the
proper section of Group 8E - Instrument Panel Sys-
tems for more information on the turn signal indica-
tor lamps. Following are general descriptions of the
major components in the hazard warning system. For
complete circuit diagrams, refer to Turn Signals in
the Contents of Group 8W - Wiring Diagrams.

OPERATION

With the hazard warning switch in the On posi-

tion, the hazard warning system is activated. When
the hazard warning system is activated, the circuitry
of the hazard warning switch and the combination
flasher will cause both the right side and the left side
turn signal indicator lamps, front park/turn signal

lamps, and rear tail/stop/turn signal lamps to flash
on and off in unison.

See the owner’s manual in the vehicle glove box for

more information on the features, use and operation
of the hazard warning system.

TURN SIGNAL SWITCH AND HAZARD
WARNING SWITCH

DESCRIPTION

The turn signal and hazard warning switches are

integral to the multi-function switch unit, which is
secured to the left side of the steering column (Fig.
1). The only visible parts of the multi-function switch
are the control stalk that extends from the left side
of the steering column, and the hazard warning
switch push button that protrudes from the top of
the steering column. The multi-function switch con-
trol stalk has both nomenclature and international
control symbols on it, which identify its many func-
tions. The hazard warning switch push button is
identified with a double triangle, which is the inter-
national control symbol for hazard warning. The
remainder of the multi-function switch is concealed
beneath the steering column shrouds.

The multi-function switch also contains circuitry

for the following functions:

• Headlamp beam selection

• Headlamp optical horn

• Windshield wipers

• Windshield washers.

The information contained in this group addresses

only the multi-function switch turn signal and haz-

ard warning functions. For information relative to
the other systems that are controlled by and circuits
that are integral to the multi-function switch, see the
group in this service manual that covers that system.
However,

the

turn

signal

and

hazard

warning

switches cannot be repaired. If these switches or any
other circuit or component of the multi-function
switch unit is faulty or damaged, the entire multi-
function switch unit must be replaced.

OPERATION

TURN SIGNAL SWITCH

The

multi-function

switch

control

stalk

that

extends from the left side of the steering column just
below the steering wheel is moved up or down to
activate the turn signal switch. When the control
stalk is moved in the upward direction, the right
turn signal switch circuitry is activated; and, when
the control stalk is moved in the downward direction,
the left turn signal switch circuitry is activated. The
turn signal switch has a detent position in each
direction that provides turn signals with automatic
cancellation, and an intermediate momentary posi-
tion in each direction that provides turn signals only
until the multi-function switch control stalk is
released.

When the turn signal switch is in a detent posi-

tion, it is turned off by one of two turn signal cancel-
ling cam lobes that are integral to the rotor of the
clockspring mechanism. Turning the steering wheel
causes the turn signal cancelling cam lobes to contact
a cancel actuator in the multi-function switch, and
the turn signal switch automatically returns to the
off position.

HAZARD WARNING SWITCH

The hazard warning switch is controlled by the

hazard warning switch push button. Push the switch
button in to unlatch the switch and activate the haz-
ard warning system, and push in on the button again
to latch the switch and turn the system off. When
the hazard warning switch is latched (hazard warn-
ing off), the push button will be in a lowered position
on the top of the steering column shroud; and, when
the hazard warning switch is unlatched (hazard
warning on), the push button will be in a raised posi-
tion.

TURN SIGNAL CANCELLING CAM

DESCRIPTION

The turn signal cancelling cam is concealed within

the steering column below the steering wheel. The
turn signal cancelling cam consists of two lobes that
are integral to the lower surface of the clockspring
