HEADLAMP SWITCH (Continued)

²Continuous Wipe Modes- The control knob of
the multi-function switch provides two continuous
wipe switch positions, low speed or high speed.
²Hazard Warning Control- The internal cir-
cuitry and hardware of the multi-function switch pro-
vide detent switching for activation and deactivation
of the hazard warning system.
²Headlamp Beam Selection- The internal cir-
cuitry and hardware of the multi-function switch pro-
vide detent switching for selection of the headlamp
high or low beams.
²Headlamp Optical Horn- The internal cir-
cuitry and hardware of the multi-function switch
includes momentary switching of the headlamp high
beam circuits to provide an optical horn feature
(sometimes referred to as flash-to-pass), which allows
the vehicle operator to momentarily flash the head-
lamp high beams as an optical signalling device.
²Intermittent Wipe Mode- The control knob of
the multi-function switch provides an intermittent
wipe mode with multiple delay interval positions.
²Turn Signal Control- The internal circuitry
and hardware of the multi-function switch provide
both momentary non-detent switching and detent
switching with automatic cancellation for both the
left and right turn signals.
²Washer Mode- A button on the end of the con-
trol stalk of the multi-function switch provides
washer system operation when the button is
depressed towards the steering column.
The multi-function switch cannot be adjusted or
repaired. If any function of the switch is faulty, or if
the switch is damaged, the entire switch unit must
be replaced.
OPERATION
The multi-function switch uses conventionally
switched outputs and a variable resistor to control
the many functions and features it provides using
hard wired circuitry. The switch is grounded at all
times through a single wire take out with an eyelet
terminal connector of the instrument panel wire har-
ness that is secured by a nut to a ground stud
located on the instrument panel armature, just above
and to the left of the glove box opening. When the
ignition switch is in the Accessory or On positions,
battery current from a fuse in the Junction Block
(JB) is provided through a fused ignition switch out-
put (run-acc) circuit. Following are descriptions of
how the multi-function switch operates to control the
many functions and features it provides:²Continuous Wipe Modes- When the control
knob of the multi-function switch is rotated to the
High or Low positions, the circuitry within the
switch provides a battery current output directly to
the high or low speed brush of the wiper motor.
When the control knob is in the Off position, the cir-
cuitry within the switch connects the output of the
wiper motor park switch to the low speed brush of
the wiper motor.
²Hazard Warning Control- The hazard warn-
ing push button is pushed down to unlatch the
switch and activate the hazard warning system, and
pushed down again to latch the switch and turn the
system off. When the hazard warning switch is
latched (hazard warning off), the push button will be
in a lowered position on the top of the steering col-
umn shroud; and, when the hazard warning switch is
unlatched (hazard warning on), the push button will
be in a raised position. The multi-function switch
hazard warning circuitry simultaneously provides a
signal to the hazard warning sense of the combina-
tion flasher to activate or deactivate the flasher out-
put, and directs the output of the flasher to the
hazard warning lamps.
²Headlamp Beam Selection- The multi-func-
tion switch control stalk is pulled towards the steer-
ing wheel past a detent, then released to actuate the
headlamp beam selection switch. Each time the con-
trol stalk is actuated in this manner, the opposite
headlamp mode from what is currently selected will
be activated. The internal circuitry of the headlamp
beam selection switch directs the output of the head-
lamp switch through hard wired circuitry to activate
the selected headlamp beam.
²Headlamp Optical Horn- The left multi-func-
tion switch control stalk is pulled towards the steer-
ing wheel to just before a detent, to momentarily
activate the headlamp high beams. The high beams
will remain illuminated until the control stalk is
released. The internal circuitry of the headlamp
beam selection switch provides a momentary ground
path to the headlamp high beams.
²Intermittent Wipe Mode- When the multi-
function switch control knob is rotated to the Delay
position, the circuitry within the switch connects the
output of the wiper motor relay to the low speed
brush of the wiper motor and provides a battery cur-
rent signal to the Central Timer Module (CTM). If
the Delay mode is selected, the control knob can then
be rotated to multiple minor detent positions, which
actuates a variable resistor within the switch and
provides a hard wired output to the CTM that sig-
nals the desired delay interval for the intermittent
wiper feature.
8L - 24 LAMPS/LIGHTING - EXTERIORBR/BE
MULTI-FUNCTION SWITCH (Continued)

²Turn Signal Control- The multi-function
switch control stalk actuates the turn signal switch.
When the control stalk is moved in the upward direc-
tion, the right turn signal circuitry is activated; and,
when the control stalk is moved in the downward
direction, the left turn signal circuitry is activated.
The multi-function switch turn signal circuitry simul-
taneously provides a signal to the turn signal sense
of the combination flasher to activate or deactivate
the flasher output, and directs the output of the
flasher to the proper turn signal lamps. The turn sig-
nal switch has a detent position in each direction
that provides turn signals with automatic cancella-
tion, and an intermediate, momentary position in
each direction that provides turn signals only until
the multi-function switch control stalk is released.
When the control stalk is moved to a turn signal
switch detent position, the cancel actuator extends
toward the center of the steering column. A turn sig-
nal cancel cam that is integral to the clockspring
mechanism rotates with the steering wheel and the
cam lobes contact the cancel actuator when it is
extended from the multi-function switch. When the
steering wheel is rotated during a turning maneuver,
one of the two turn signal cancel cam lobes will con-
tact the turn signal cancel actuator. The cancel
actuator latches against the cancel cam rotation in
the direction opposite that which is signaled. In other
words, if the left turn signal detent is selected, the
lobes of the cancel cam will ratchet past the cancel
actuator when the steering wheel is rotated to the
left, but will unlatch the cancel actuator as the steer-
ing wheel rotates to the right and returns to center,
which will cancel the turn signal event and release
the control stalk from the detent so it returns to the
neutral Off position.
²Washer Mode- Pushing the button on the end
of the multi-function switch control knob towards the
steering column provides a battery current output
through the momentary single pole, single throw
washer switch circuitry to operate the washer pump/
motor and provides a signal to the CTM. If the wip-
ers are not operating when the washer switch is
actuated, the CTM will operate the wiper motor for
as long as the washer switch is depressed plus about
three additional wipe cycles. If the wipers are oper-
ating in the intermittent mode when the washer
switch is actuated, the CTM will operate the wiper
motor at a fixed low speed for as long as the washer
switch is depressed plus about three additional wipe
cycles before the wipers return to the selected inter-
mittent wipe interval.DIAGNOSIS AND TESTING - MULTI-FUNCTION
SWITCH

wiring information includes wiring diagrams, proper
wire and connector repair procedures, details of wire
harness routing and retention, connector pin-out
