INSTALLATION
(1) Install antenna body and cable from under-
neath fender (Fig. 12). (2) Install gasket, adapter, and cap nut. Tighten
cap nut to 14 N Im (125 in. lbs.) with Antenna Nut
Wrench C-4816. (3) Install antenna mast into antenna body until
sleeve bottoms on antenna body (Fig. 11). (4) Route cable to radio if necessary.
BENCH TEST FOR ANTENNA MALFUNCTION
It is also possible to check short or open circuits
with an ohmmeter or continuity light once the an-
tenna has been removed from the vehicle. (1) Continuity should be present between the tip of
the mast and radio end pin (Fig. 13 and 14).
(2) No continuity should be observed or a very high
resistance of several megohms between the ground
shell of the connector and radio end pin.
(3) Continuity should be observed between the ground
shell of the connector and the mounting hardware.
Wiggle cable over its entire length to reveal inter-
mittent short or open circuits during step 1, 2 and 3.
POWER ANTENNA
OPERATION
The power operated radio antenna (Fig. 15) is a
telescoping type antenna, extended and retracted by a
reversible electric motor. The Automatic Power Antenna is controlled by a
combination of an external relay and limit switches
built into the antenna motor housing. The antenna is
actuated when radio is switched ON and the ignition
switch in ON or ACCESSORY position. The antenna
mast should extend. When the ignition switch or radio
is turned OFF the antenna mast should fully retract
and declutch.
Many antenna problems may be avoided by frequent
cleaning of the antenna mast telescoping sections. Clean
the antenna mast sections with a clean soft cloth.
Before an antenna is removed, the antenna perfor-
mance should be tested to decide if it is a reception
problem or an operational problem. Whenever an operational malfunction occurs, first
verify that the radio antenna wire harness is properly
connected. Check all connectors before starting normal
diagnosis and repair procedures. Refer to Power An-
tenna Electrical Diagnosis Chart (Fig. 16).

WARNING: ON VEHICLES EQUIPPED WITH AIR

DURES.
The horn circuit consists of a horn switch, horn re-
lay, and horns. The horn circuit feed is from the fuse
box to the number 1 terminal on the horn relay.
When the horn switch is depressed, this completes
the circuit to ground. This activates the horn relay
and an set of contacts in the relay to close, which al-
lows current to flow to the horn(s). The horn ground
wire is attached to the headlamp ground screw (Fig.
1).
TESTING HORN SYSTEM
HORNS WILL NOT SOUND
If the horns do not sound, check for a blown horn
fuse in the fuse block. If the fuse is blown, replace it
with the same fuse type. If the horns fail to sound
and the new fuse blows when depressing the horn
switch, a short circuit in the horn or the horn wiring
between the fuse terminal and the horn is responsi-
ble. If the fuse is good, disconnect wire connector at
horn. Using an test lamp, connect one lead to the
negative terminal and the other to the positive ter-
minal (Fig. 2). Depress the horn switch, the test
lamp should illuminate. If not connect the test lamp wire to a good ground and depress the horn switch. If
test lamp lights inspect ground wire circuit and re-
pair as needed.
If the test lamp fails to illuminate, check for a de-
fective horn relay. Substituting a known good horn
relay in the circuit. If the test lamp illuminates
when depressing the horn switch, the original relay
is defective. If the test lamp fails to illuminate with
a known good relay, unplug that relay. Connect a
jumper wire from the battery terminal to the horn
terminal on the relay terminal board (Fig. 3, 4, or 5).
If the test lamp connected in place of the horns, fails
to illuminate an open circuit in the wiring between
the relay terminal and the horn switch is at fault re-
pair as necessary.
HORNS SOUND CONTINUOUSLY
CAUTION: Continuous sounding of horns may
cause relay to fail.
Should the horns sound continuously, unplug the
horn relay from the terminal board inside the pas-
senger compartment. Plug in a known good relay. If
the horns stop blowing, relay is defective and must
be replaced. Should the horns still sound, proceed as
follows: Connect one voltmeter lead to battery termi-
nal on relay board and the other lead to switch ter-
minal. Refer to Figs. 6, 7, or 8. Voltmeter will

GENERAL INFORMATION
WARNING: ON VEHICLES EQUIPPED WITH AIR-

AIRBAG REMOVAL PROCEDURES.
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.
