WIPERSÐSTANDARD
A circuit breaker powers the standard wiper sys-
tem. The standard wiper system operates at either
LOW or HIGH speeds.
In the ACCESSORY or RUN position, the ignition
switch connects circuit A1 from fuse 6 in the Power
Distribution Center (PDC) with circuit A48. Circuit
A48 supplies voltage to circuit F86 through the circuit
breaker near the left kick panel.
Circuit F86 is double crimped at the circuit breaker
and supplies power to the wiper switch and the park
switch in the wiper motor. Circuit Z1 from the wiper
motor provides ground for the wiper motor and
switch.
When the operator moves the wiper switch to the
LOW position, battery voltage passes through the
switch to circuit V3. Circuit V3 feeds the wiper motor
low speed brushes. If the operator selects wiper
HIGH speed operation, the wiper switch passes cur-
rent to circuit V4. Circuit V4 feeds the wiper motor
high speed brushes.
As the windshield wiper motor turns, the park
switch, internal to the motor, moves from its DOWN
position to the UP position. When the wiper switch is
turned OFF, the V55 circuit prevents the wipers from
stopping in any position but park.
The windshield washer uses a pump motor located
inside the windshield washer fluid reservoir. When
the washer switch is pressed, power is supplied
through the wiper switch to the pump motor on cir-
cuit V10. Circuit Z1 provide ground for the pump
motor.
HELPFUL INFORMATION
Circuit Z1 also provides ground for the rear wiper
washer pump, radiator fan motor and front end light-
ing.
WIPERSÐINTERMITTENT
A circuit breaker powers the standard wiper sys-
tem. The intermittent wiper system operates at either
LOW or HIGH or DELAY speeds.
In the ACCESSORY or RUN position, the ignition
switch connects circuit A1 from fuse 6 in the PDC
with circuit A48. Circuit A48 supplies voltage to cir-
cuit F86 through the circuit breaker near the left kick
panel.Circuit F86 is double crimped at the circuit breaker
and supplies power to the wiper switch and the park
switch in the wiper motor. Circuit Z1 from the wiper
motor provides ground for the wiper motor and
switch.
When the operator moves the wiper switch to the
LOW position, battery voltage passes through the
switch to circuit V3. Circuit V3 feeds the wiper motor
low speed brushes. If the operator selects wiper
HIGH speed operation, the wiper switch passes cur-
rent to circuit V4. Circuit V4 feeds the wiper motor
high speed brushes.
The DELAY portion of the wiper switch contains a
variable resistor. The variable resistor connects to the
intermittent wiper module through the wiper switch
harness. The amount of delay selected by the operator
determines the voltage drop through the resistor and
the voltage level received by the intermittent wiper
module.
After the intermittent wiper control module deter-
mines the amount of delay selected, it cycles the
wipers by periodically energizing circuit V3. Circuit
V3 powers the wiper motor low speed brushes.
As the windshield wiper motor turns, the park
switch, internal to the motor, moves from its DOWN
position to the UP position. When the wiper switch is
turned OFF, the V55 circuit prevents the wipers from
stopping in any position but park.
The windshield washer uses a pump motor located
inside the windshield washer fluid reservoir. When
the washer switch is pressed, power is supplied
through the wiper switch to the pump motor on cir-
cuit V10. Circuit Z1 provides ground for the pump
motor.

Circuit Z1 also provides ground for the rear wiper
washer pump, radiator fan motor and front end light-
ing.
REAR WIPER SYSTEM
In the RUN position, the ignition switch connects
circuit A1 from fuse 6 in the PDC with circuit A38.
Circuit A38 connects to a fuse block bus bar that
powers circuit V15 through the fuse in cavity 1. Cir-
cuit V15 supplies power to the rear wiper switch.
J8W-53 WIPERSÐXJ VEHICLES 8W - 53 - 1
In the WIPE or WASH positions, the rear wiper
switch supplies voltage to the wiper motor on circuit
V13. Circuit Z1 provides ground for the wiper motor.
The rear windshield washer uses a pump motor lo-
cated inside the windshield washer fluid reservoir.
When the rear wiper switch is pressed, power is sup-
plied through the wiper switch to both the rear wiper
and the pump motor on circuit V20. Circuit Z1 pro-
vides ground for the pump motor.
As the rear wiper motor turns, the park switch, in-
ternal to the motor, moves from the RUN position to
the PARK position. When the wiper switch is turned
OFF, the F20 circuit prevents the wipers from stop-
ping in any position but park.DIAGRAM INDEX

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 realize 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 pos-
sible, with regard to function only.
The wiring diagram show circuits for all wheel-
bases. If there is a difference in systems or compo-
nents between wheel-bases, an identifier is placed
next to the component.
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 LOCATIONS
Section 8W-90 contains Connector Location illus-
trations. The illustrations contain the connector
number and component identification. Connector Lo-
cation charts in Section 8W-90 reference the illustra-
tion 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 number on the Diagram
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.
