HORNS SOUND CONTINUOUSLY
CAUTION: Continuous sounding of horns may
cause relay to fail.
The horn switch (membrane) sometimes can be the
cause without the switch being depressing.
(1) Remove the horn relay from the junction block.
(2) Using a continuity tester, test continuity from
the X3 cavity of the horn relay to ground. Refer to
Group 8W, Wiring Diagrams for circuit information.
(a) If continuity is detected, proceed to step Step
3.
(b) If NO continuity, replace the horn relay.
(3) Remove the airbag/horn pad from the steering
wheel and disengage horn connector.
(4) Install horn relay into junction block.
(a) If horn does not sound, replace airbag cover/
horn pad.
(b) If horn sounds, repair grounded X3 circuit
from junction block to clockspring in steering in
steering column. Refer to Group 8W, Wiring Dia-
grams.
HORN SYSTEM
Refer to Horn System Test below. If the horn does
not sound, check horn fuse located in the Power Dis-
tribution Center. If the fuse is blown, replace with
the correct fuse. If the horn 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 responsible, or a
defective horn switch allowed the horn to burn out is
responsible.
If the fuse is OK, test horn relay refer to Horn
Relay Test.
If the relay is OK, test horn. Refer to Horn System
Test.
CAUTION: Continuous sounding of horn may
cause horn relay to fail.
Should the horn sound continuously:
²Unplug the horn relay from Power Distribution
Center.
²Refer to Horn Relay Test.
Refer to Group 8W, Wiring Diagrams for circuit
and wiring information.
HORN SYSTEM TEST
CONDITION POSSIBLE CAUSE CORRECTION
Horn sounds continuously.
NOTE: Immediately unplug horn
relay in the Power Distribution
Center (PDC)(1) Faulty horn relay.
(2) Horn control circuit to relay
shorted to ground.
(3) Pinched horn switch wire under
Driver Airbag Module.
(4) Defective horn switch(1) Refer to horn relay test.
(2) Check terminal 85 in Junction
Block for continuity to ground. If
continuity to ground indicates:
(a) Steering Wheel horn switch/lead
shorted to ground.
(b) Wiring harness shorted to
ground. Find the short and repair as
necessary.
(3) Replace Driver Airbag Module.
(4) Replace Driver Airbag Module.
Horn sound intermittently as the
steering wheel is turned.(1) Horn relay control circuit X3 is
shorted to ground inside steering
column or wheel.
(2) Pinched horn switch wire under
Driver Airbag Module
(3) Defective horn switch(1) Remove Driver Airbag Module
and/or wheel. Check for rubbing or
loose wire/connector, repair as
necessary.
(2) Replace Driver Airbag Module.
(3) Replace Driver Airbag Module.
Horn does not sound (1) Check fuse 6 in PDC
(2) No Voltage at horn relay
terminals 30 & 86, and fuse is OK.
(3) Open circuit from terminal 85 of
the horn relay to horn switch, X3
circuit.
(4) Defective or damaged horn.
(5) Defective horn switch(1) Replace fuse if blown repair as
necessary.
(2) No voltage, repair the A6 circuit
as necessary.
(3) Repair circuit as necessary.
(4) Voltage at horn when horn switch
is pressed, replace horn.
(5) Replace Driver Airbag Module.

DIAGNOSIS AND TESTING (Continued)

CONDITION POSSIBLE CAUSE CORRECTION
Fuse blows when horn sounds (1) Short circuit in horn or horn
wiring(1) Remove horn relay, check for
shorted horn or horn wiring.
Disconnect horn wire harness to
isolate short and repair as
necessary.
Fuse blows without blowing horn (1) Short circuit (1) Remove relay, install new fuse, if
fuse does not blow replace horn
relay. If fuse blows with relay
removed, check for short to ground
with ohmmeter on circuit between
terminals 30 & 86 and the fuse
terminal. Repair as necessary.
NOTE: For wiring repairs refer to
Group 8W, Wire Diagrams.
REMOVAL AND INSTALLATION
HORN SWITCH
The horn switch is molded into the airbag cover.
The horn switch cannot be serviced separately. Refer
to Group 8M, Restraint System for Driver Airbag
Module Removal and Installation procedures.
HORNS
REMOVAL
(1) Hoist and support the front of the vehicle on
safety stands.
(2) From behind the front fascia and forward of
the left front wheel, disconnect the wire connectors
from horn.
(3) Remove the mount bracket attaching nut from
the bottom of radiator closure panel. Do not remove
the horn from mounting bracket (Fig. 4).

DIAGNOSIS AND TESTING (Continued)

Refer to Group 25, for further information and use-
age of the DRB scan tool and a more complete list of
Diagnostic Trouble Code.
SPEED CONTROL SLOWS DOWN BY ITSELF
Test vehicle speed sensor, refer to group 8E. If sen-
sor fails replace sensor, if it passes perform the fol-
lowing test:
(1) Perform the speed control switch test on the
DECEL switch, if it fails replace switch.
(2) If the switch passes, conduct the vacuum sup-
ply test.
(3) If it passes, conduct the servo vacuum test. If it
fails replace servo.
(4) If continuity, replace the PCM.
SPEED CONTROL ELECTRICAL TEST
Electronic speed control systems may be tested
using two different methods. One involves use of a
DRB. If this test method is desired, refer to the Pow-
ertrain Diagnostic Test Procedures for charging and
speed control system manual.The other test method uses a volt/ohm meter. The
volt/ohm meter method is described in the following
tests.
If any information is needed concerning wiring,
refer to Group 8W, Wiring Diagrams (Fig. 2).
CAUTION: When test probing for voltage or conti-
nuity at electrical connectors, care must be taken
not to damage connector, terminals, or seals. If
these components are damaged, intermittent or
complete system failure may occur.
When electrical connections are removed, corrosion
should be removed from electrical terminals and a
light coating of Mopar Multi-Purpose Grease, or
equivalent, applied. Inspect connectors for damage
terminals.
A poor connection can cause a complete or inter-
mittent malfunction and is also the only connection
in the circuit, that can not be tested. For this reason,
a loose connection may be misdiagnosed as a compo-
nent malfunction.

GENERAL INFORMATION
GENERAL INFORMATION
NS vehicles use lighting on the interior and exte-
rior of the vehicle for illuminating and indicating
purposes. Lighting circuits are protected by fuses.
Lighting circuits require an overload protected power
source, on/off device, lamps and body ground to oper-
ate properly. Plastic lamps require a wire in the har-
ness to supply body ground to the lamp socket.
Replace sockets and bulbs that are corroded.
Some of the interior and exterior lighting functions
are governed by the body controller. The headlamp,
dome, and the door ajar switches provide signals to
the body controller. The body controller in turn acti-
vates relay(s) in order to provide either a ground or
feed line to the appropriate lamp(s).
Wire connectors can make intermittent contact or
become corroded. Before coupling wire connectors,
inspect the terminals inside the connector. Male ter-
minals should not be bent or disengaged from the
insulator. Female terminals should not be sprung
open or disengaged from the insulator. Bent and
sprung terminals can be repaired using needle nose
pliers and pick tool. Corroded terminals appear
chalky or green. Corroded terminals should be
replaced to avoid recurrence of the problem symp-
toms.
Begin electrical system failure diagnosis by testing
related fuses in the fuse block and power distribution
center. Verify that bulbs are in good condition andtest continuity of the circuit ground. Refer to Group
8W, Wiring Diagrams, for component location and cir-
cuit information.SAFETY PRECAUTIONS
WARNING: EYE PROTECTION SHOULD BE USED
WHEN SERVICING GLASS COMPONENTS. PER-
SONAL INJURY CAN RESULT.
CAUTION: Do not touch the glass of halogen bulbs
with fingers or other possibly oily surface, reduced
bulb life will result.
Do not use bulbs with higher candle power than
indicated in the Bulb Application table at the end of
this group. Damage to lamp and/or Daytime Run-
ning Lamp Module can result.
Do not use fuses, circuit breakers or relays hav-
ing greater amperage value than indicated on the
fuse panel or in the Owners Manual.
When it is necessary to remove components to ser-
vice another, it should not be necessary to apply
excessive force or bend a component to remove it.
Before damaging a trim component, verify hidden
fasteners or captured edges are not holding the com-
ponent in place.

HEADLAMP LEVELING MOTOR
This vehicle is equipped with a remote headlamp
leveling system. This system allows the driver to
adjust the vertical headlamp aim from the interior of
the vehicle to compensate for passenger or cargo
load. A headlamp leveling switch is located in the
instrument panel and controls the headlamp leveling
motor found on the back of the headlamp module.
