TURN SIGNALSÐAC, AY, AA AND AP BODIES
The turn signals are part of the multi-function switch.
Which contains electrical circuitry for turn signal, cor-
nering lamps, hazard warning, headlamp beam select,
headlamp optical horn, windshield wiper, pulse wipe
and windshield washer switching. The integrated switch
assembly is mounted to the left hand side of the steer-
ing column. When the driver wishes to signal his inten-
tions to change direction of travel, he moves the lever
upward to cause the right signals to flash and down-
ward 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 posi-
tion, a canceling cam of two lobes molded to the clock-
spring mechanism comes in contact with the cancel
actuator on the turn signal multi-function switch as-
sembly. Either cam lobe, pushing on the cancel actua-
tor, 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, 1 of 2 indicator
lamps mounted in the instrument cluster flashes in
unison with the turn signal lamps, indicating to the
driver that the system is operating.
AG AND AJ BODIES
The turn signals are actuated with lever on the left
side of the instrument panel switch pod. When the
driver wishes to signal his intentions to change di- rection 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 deacti-
vated automatically. The cancellation switch in the
steering column sends a signal to a remote turn sig-
nal switch in the switch pod to cancel the turn signal
function. As the steering wheel returns to the
straight ahead position from a turn, a cancel cam
which is located on the steering wheel contacts a
cancel flipper located on the cancellation switch.
When the flipper is contacted by the cancel cam in
the proper rotational direction, the cancel switch
sends a signal to the remote turn signal switch. 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 po-
sition 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, 1 of 2 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
The hazard warning system is actuated by a push
button located on the top of the steering column be-
tween the steering wheel and the instrument panel.
The hazard switch is identified with a double trian-
gle on top of the button. 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.
CHIME FUNCTIONÐAC, AG, AJ AND AY
The chime will sound after the vehicle has traveled
a distance of 0.6 miles at a speed above 15 miles per
hour.

TESTING PROCEDURES
MULTI-FUNCTION SWITCH TESTS AA, AC, AP, AND AY BODIES
The multi-function switch contains electrical cir-
cuitry for turn signal, cornering lamps (optional),
hazard warning, headlamp beam select, headlamp
optical horn, windshield wiper, pulse wipe, and wind-
shield washer switching. This integrated switch as-
sembly 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. Re-
fer to Fig. 1 for diagnosis. To test the switch, first disconnect the negative
battery cable, then remove the upper and lower col-
umn covers to gain access to the switch connector.
Remove switch connector. Using an ohmmeter, test
for continuity (no resistance) between the terminals
of the switch as shown in the following continuity
charts (Fig 2 or 3).
DUAL-FUNCTION SWITCH TESTSÐAG AND AJ BODIES
The dual-function switch contains electrical cir-
cuitry for hazard warning switching, and circuitry
and electronics for turn signal cancellation. The
switch assembly is mounted to the left hand side of
the steering column. To test the hazard warning portion of the switch,
first disconnect the negative battery cable, then re-
move the upper and lower steering column covers to
gain access to the switch connector. Remove switch
connector (Fig. 4). Using an ohmmeter, test for con-
tinuity between the terminals of the switch as shown
in the following continuity chart (Fig. 5). To test the cancellation portion of the switch:
(1) Reconnect battery and switch connector (Fig.
5). (2) Connect voltmeter positive lead (+) to pin 8
and negative lead (-) to ground. (3) Place ignition switch to the ON position. Volt-
meter should read battery voltage. If no voltage is
present, check feed wire to pin 8. If battery voltage is
present continue with switch test.
RIGHT CANCELLATION TEST (1) Connect one side of a jumper wire to pin 3 and
the other end of jumper wire to ground. (2) Connect the positive lead (+) of a voltmeter to
pin 5 and the negative lead (-) to ground.
CAUTION: Do not allow pin 5 to become grounded
during test, switch failure will result.
(3) With the ignition switch in the ON position,
push the cancellation pawl down and read the volt-
meter. (4) The voltmeter should show at least 9 volts. (5) If voltage is 0 to 8 volts the cancellation switch
is defective. If voltage is 9 volts or more the cancel-
lation switch is working correctly.
LEFT CANCELLATION TEST
(1) Connect one side of a jumper wire to pin 4 and
the other end of jumper wire to ground. (2) Connect the positive lead (+) of a voltmeter to
pin 5 and the negative lead (-) to ground.
CAUTION: Do not allow pin 5 to become grounded
during test, switch failure will result.
(3) With the ignition switch in the ON position,
push the cancellation pawl up and read the voltme-
ter. (4) The voltmeter should show at least 9 volts.
(5) If voltage is 0 to 8 volts the cancellation switch
is defective. If voltage is 9 volts or more the cancel-
lation switch is working correctly.
REMOTE TURN SIGNAL SWITCH TESTÐAA AND AJ BODIES
The remote turn signal switch is located on the left
side of the instrument panel switch pod. To test, re-
move switch pod assembly from instrument panel.
Using an ohmmeter, test for continuity between the
terminals of the switch as shown in the following
continuity chart (Fig. 6). The white 7 way connector
next to the 14 way connector must be connected
when performing continuity checks.
CANCELLATION SOLENOID TESTÐAG AND AJ BODIES
To test the turn signal cancellation solenoid:
(1) Remove switch pod from instrument panel.
(2) Connect one end of a jumper wire to the posi-
tive terminal of the battery, the other end to pin 6 of
the turn signal switch 14 way connector. (3) Place turn signal switch in the left turn mode.
(4) Take a second jumper wire and connect one end
to a good ground. Momentarily touch the other end of
the jumper wire to pin 11 or 14. The solenoid should
energize, and return the switch to its center OFF po-
sition. (5) Place turn signal switch in the right turn
mode. (6) Repeat step 4. The solenoid should energize,
and return the switch to its center OFF position. (7) If switch does not return to center in either di-
rection, the switch is defective.

TURN SIGNAL AND HAZARD WARNING FLASHER
LOCATION
AA, AC, AP AND AY BODIES
The turn signal flasher and the hazard warning
flasher are two separate plug-in type units. On AC and AY both flashers are on the relay mod-
ule (Fig. 10).
On AA and AP Bodies the hazard flasher is located
on the relay module (Fig. 11). The turn signal flasher
is on the driver's side of A/C duct for AA Body (Fig.
12) and center A/C duct for AP Body.
AG AND AJ BODIES
The turn signal flasher and the hazard warning
flasher are combined into one unit called a combina-
tion flasher (combo-flasher). The combo-flasher con-
trols the flashing of the hazard warning system and the turn signal system. An inoperative bulb or in-
complete turn signal circuit will result in an increase
in flasher speed. The combo-flasher is located under the instrument
panel, right of the steering column and is clipped on
the A/C distribution duct. The combo-flasher is yel-
low in color for ease of identification.TURN SIGNAL RELAYSÐAG AND AJ BODIES
The AG and AJ models are equipped with four
turn signal relays.

8J - 6 TURN SIGNALS AND HAZARD WARNING FLASHER Ä

One relay controls the right rear turn signal and
stop lamp. The second relay controls the left rear
turn signal and stop lamp. The third relay controls
the right front turn signal. The fourth relay controls
the left front turn signal. The turn signal relays are located in the relay
bank, underneath the driver's side of the instrument
panel. The four turn signal relays are identical and
can be interchanged. The turn signal relays do not cycle on and off with
the turn signal lamp. Their function is to complete the turn signal circuit when the turn signal is
switched on. Turn signal cycling is done by the com-
bination flasher. To test the relay, remove the suspect relay and
switch it with 1 of the other 3 turn signal relays. If
the problem follows the relay, replace that relay. If
the problem remains in the same circuit, the relay is
not the problem. Refer to Group 8W, Wiring Dia-
grams.
