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

TURN SIGNAL CANCEL CAM
DESCRIPTION
The turn signal cancel cam is concealed within the
steering column below the steering wheel. The turn
signal cancel cam consists of two lobes that are inte-
gral to the lower surface of the clockspring rotor. The
clockspring mechanism provides turn signal cancella-
tion as well as a constant electrical connection
between the horn switch, driver airbag, speed control
switches, and remote radio switches on the steering
wheel and the instrument panel wire harness on the
steering column. The housing of the clockspring is
secured to the steering column and remains station-
ary. The rotor of the clockspring, including the turn
signal cancel cam lobes rotate with the steering
wheel.
The turn signal cancel cam is serviced as a unit
with the clockspring and cannot be repaired. If faulty
or damaged, the entire clockspring unit must be
replaced. (Refer to 8 - ELECTRICAL/RESTRAINTS/
CLOCKSPRING - REMOVAL).
OPERATION
The turn signal cancel cam has two lobes molded
into the lower surface of the clockspring rotor. When
the turn signals are activated by moving the multi-
function switch control stalk to a detent position, a
turn signal cancel actuator is extended from the
inside surface of the multi-function switch housing
toward the center of the steering column and the
turn signal cancel cam. When the steering wheel is
rotated during a turning maneuver, one of the two
turn signal cancel cam lobes will contact the turn sig-
nal cancel actuator. The cancel actuator latches
against the cancel cam rotation in the direction oppo-
site 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 steering 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.

READING LAMP
DESCRIPTION
The overhead console in this vehicle is equipped
with two individual reading and courtesy lamps. The
lamp lenses are the only visible components of these
lamps. The reading and courtesy lamp lenses are
mounted in the overhead console housing between
the garage door opener storage bin and the sun-
glasses storage bin. Each lamp has its own switch,
bulb, reflector and lens; but both lamps share a com-
mon lamp housing within the overhead console.
The overhead console reading and courtesy lamps
operate on battery current that is provided at all
times, regardless of the ignition switch position. The
ground feed for the lamps is switched through the
integral reading and courtesy lamp switches or
through the door jamb switches. Each lamp is
designed and aimed to provide illumination that will
be directed only to that side of the vehicle on which
the lamp is located.The reading and courtesy lamp lenses, bulbs and
the lamp housing and reflector unit are available for
service replacement. The reading and courtesy lamp
switches, bulb holders and wiring are only available
as part of the overhead console wire harness. If
either of the lamp switches or bulb holders is faulty
or damaged, the entire overhead console wire har-
ness assembly must be replaced.
For service of the reading and courtesy lamp bulbs,
refer to the appropriate wiring information. The wir-
ing information includes wiring diagrams, proper
wire and connector repair procedures, details of wire
harness routing and retention, connector pin-out
information and location views for the various wire
harness connectors, splices and grounds.
OPERATION
All reading and courtesy lamps located in the over-
head console are activated by the door jamb switches.
When all of the doors are closed, these lamps can be
individually activated by depressing the correspond-
ing lens. When any door is open, depressing the lamp
lenses to activate the lamp switches will not turn the
lamps off.
See the owner's manual in the vehicle glove box for
more information on the use and operation of the
overhead console reading and courtesy lamps.
