DESCRIPTION AND OPERATION
HOW TO USE THIS GROUP
The purpose of this group is to show the electrical
circuits in a clear, simple fashion and to make trou-
bleshooting easier. Components that work together
are shown together. All electrical components used in
a specific system are shown on one diagram. The feed
for a system is shown at the top of the page. All
wires, connectors, splices, and components are shown
in the flow of current to the bottom of the page. Wir-
ing which is not part of the circuit represented is ref-
erenced to another page/section, where the complete
circuit is shown. In addition, all switches, compo-
nents, and modules are shown in theat rest posi-
tion with the doors closed and the key removed
from the ignition.
If a component is part of several different circuits,
it is shown in the diagram for each. For example, the
headlamp switch is the main part of the exterior
lighting, but it also affects the interior lighting and
the chime warning system.It is important to real-
ize that no attempt is made on the diagrams to
represent components and wiring as they
appear on the vehicle. For example, a short
piece of wire is treated the same as a long one.
In addition, switches and other components are
shown as simply as possible, with regard to
function only.
SECTION IDENTIFICATION
Sections in Group 8W are organized by sub-sys-
tems. The sections contain circuit operation descrip-
tions, helpful information, and system diagrams. The
intention is to organize information by system, con-
sistently from year to year.
CONNECTOR/GROUND LOCATIONS
Section 8W-90 contains connector/ground location
illustrations. The illustrations contain the connector
name (or number)/ground number and component
identification. Connector/ground location charts in
Section 8W-90 reference the illustration number for
components and connectors.
Section 8W-80 shows each connector and the cir-
cuits involved with that connector. The connectors
are identified using the name/number on the Dia-
gram pages.
SPLICE LOCATIONS
Splice Location charts in Section 8W-70 show the
entire splice, and provide references to other sections
the splice serves.
Section 8W-95 contains illustrations that show the
general location of the splices in each harness. The
illustrations show the splice by number, and provide
a written location.

circuit being tested. Low or no resistance means good
continuity.
TESTING FOR A SHORT TO GROUND
(1) Remove the fuse and disconnect all items
involved with the fuse.
(2) Connect a test light or a voltmeter across the
terminals of the fuse.
(3) Starting at the fuse block, wiggle the wiring
harness about six to eight inches apart and watch
the voltmeter/test lamp.
(4) If the voltmeter registers voltage or the test
lamp glows, there is a short to ground in that gen-
eral area of the wiring harness.
TESTING FOR A SHORT TO GROUND ON
FUSES POWERING SEVERAL LOADS
(1) Refer to the wiring diagrams and disconnect or
isolate all items on the fused circuit.
(2) Replace the blown fuse.
(3) Supply power to the fuse by turning ON the
ignition switch or re-connecting the battery.
(4) Start connecting the items in the fuse circuit
one at a time. When the fuse blows the circuit with
the short to ground has been isolated.
TESTING FOR A VOLTAGE DROP
(1) Connect the positive lead of the voltmeter to
the side of the circuit closest to the battery (Fig. 12).
(2) Connect the other lead of the voltmeter to the
other side of the switch or component.
(3) Operate the item.(4) The voltmeter will show the difference in volt-
age between the two points.
TROUBLESHOOTING WIRING PROBLEMS
When troubleshooting wiring problems there are
six steps which can aid in the procedure. The steps
are listed and explained below. Always check for non-
factory items added to the vehicle before doing any
diagnosis. If the vehicle is equipped with these items,
disconnect them to verify these add-on items are not
the cause of the problem.
(1) Verify the problem.
(2) Verify any related symptoms. Do this by per-
forming operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
(3) Analyze the symptoms. Use the wiring dia-
grams to determine what the circuit is doing, where
the problem most likely is occurring and where the
diagnosis will continue.
(4) Isolate the problem area.
(5) Repair the problem.
(6) Verify proper operation. For this step check for
proper operation of all items on the repaired circuit.
Refer to the wiring diagrams.
SERVICE PROCEDURES
WIRING REPAIR
When replacing or repairing a wire, it is important
that the correct gauge be used as shown in the wir-
ing diagrams. The wires must also be held securely
in place to prevent damage to the insulation.

DESCRIPTION AND OPERATION
HORNS
The horn system is powered by a 15 amp fuse
located in the Power Distribution Center (PDC)
which is HOT at all times on circuit F31. This circuit
supplies voltage to the coil and contact side of the
horn relay.
When the operator presses the horn switch, a
ground path is completed on the coil side of the horn
relay through the switch. The horn relay, located in
the PDC, then CLOSES the relay contacts. Voltage is
passed through the CLOSED relay contacts on circuit
X2 to the horn. Grounding for the horn is on the Z1
circuit to the left headlamp ground which is located
on the left side of the radiator closure panel.
HELPFUL INFORMATION
²Check the 15 amp fuse in the PDC.²Press the horn switch and listen for the horn
relay to click. A clicking relay indicates voltage is
present up to the switch.
²Check for a good ground at the left headlamp
ground.
CIGAR LIGHTER
The cigar lighter in this vehicle uses a cigar lighter
relay and a cigar lighter element. Power for the cigar
lighter relay is supplied by two sources.
Power for the coil side of the relay is supplied by
circuit F13. This circuit is protected by a 20 amp fuse
located in the fuse block. Power for the contact side
of the relay is supplied on circuit F38. The F38 cir-
cuit is protected by a 15 amp fuse.
Ground for the cigar lighter element and relay is
supplied on circuit Z1.
8W - 41 - 4 8W - 41 HORNS/CIGAR LIGHTERPL

Downloaded from www.Manualslib.com manuals search engine The second ground path is through the headlamp
switch. Circuit M23 is spliced in with the time out
relay. When the operator turns the headlamp switch
to the dome lamp ON position, a ground path is pro-
vided through the switch on the Z1 circuit. This
ground terminates at the instrument panel left cen-
ter support.
On vehicles equipped with Remote Keyless Entry
(RKE) the M23 circuit is spliced to the RKE module.
This allows the lamp to be turned ON when a valid
signal is reveived by the RKE module from the trans-
mitter.
MAP/READING LAMPS
The map/reading lamps are powered by the M1 cir-
cuit from the Power Distribution Center (PDC). This
circuit is the Ignition-Off Draw circuit and protected
by a 10 amp fuse. The M1 circuit is spliced and pro-
vides power for the visor/vanity lamps, radio, power
mirrors, dome lamp, time delay relay, and other inte-
rior lamps.
Ground for the lamps is provided from two sources.
One is the Z3 circuit which is spliced in with the
glove box lamp and terminates at the instrument
panel left center support. The second ground is pro-
vided on circuit M23. This circuit is spliced in with
the time out relay so the lamps will turn ON when
any door is OPENED.
On vehicles equipped with Remote Keyless Entry
(RKE) the M23 circuit, which is the ground circuit
when a door is OPENED, is connected to the RKE
module. The module will provide a ground path for
the lamps with a valid signal from the transmitter.
GLOVE BOX LAMP
The glove box lamp receives power on the M1 cir-
cuit from the 10 amp fuse located in the Power Dis-
tribution Center (PDC). A switch, wired in series
after the lamp, CLOSES when the glove box door is
opened, and completes a path to ground on the Z3
circuit.
The Z3 circuit is spliced in with the ash receiver
lamp, PRNDL lamp, and the time delay relay. The Z3
circuit terminates at the instrument panel left center
support.
ASH RECEIVER LAMP
The ash receiver lamp receives power on the E2
circuit from the 4 amp fuse located in the fuse block
in cavity 12. The fuse receives power from the head-
lamp switch. Circuit E2, which is HOT at all times,
also powers the Transmission Range Indicator
(PRNDL) lamp.
When the headlamp switch is moved to the PARK
or ON position, current flows through the fuse to the
ash receiver lamp. The ground for the lamp is sup-
plied on the Z3 circuit, and terminates at the instru-
ment panel left center support. This circuit is also
spliced in with the PRNDL lamp, the ignition switch
lamp, and the glove box lamp.
UNDERHOOD LAMP
Power for the underhood lamp is supplied on cir-
cuit M1. This is the Ignition-Off Draw (IOD) circuit
and is protected by a 10 amp fuse located in the
Power Distribution Center (PDC).
When the hood is raised a ground path is com-
pleted through the mercury switch to a case ground
illuminating the lamp.
TRUNK LAMP
The trunk lamp uses a case-grounded switch
located on the trunk latch. The switch is normally
OPEN. When the deck lid is opened, the switch
CLOSES, completing a path to ground on circuit M4.
The M1 circuit provides power to the lamp, and is
HOT at all times.
HELPFUL INFORMATION
²Check the 10 amp fuse located in the Power Dis-
tribution Center (PDC) for the trunk lamp, under-
hood lamp, visor/vanity lamps, dome lamp, time
delay relay, and the glove box lamp.
²Check for a good ground at the instrument panel
left center support.
²Check the door switches for a good ground.
²Check the 4 amp fuse in the fuse block, cavity
12.
