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.
HELPFUL INFORMATION

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
