JEEP YJ 1995 Service And Repair Manual

TURN SIGNALS
COMBINATION FLASHER
In the ACCESSORY or RUN position, the ignition
switch connects circuit A1 from fuse 6 in the Power
Distribution Center (PDC) to circuit A48. Circuit A48
feeds circuit F83 through fuse 8 in the fuse block.
Circuit F83 powers the combination flasher for the
turn signals. Circuit L9 from fuse 4 in the PDC sup-
plies battery voltage to the combination flasher for
the hazard lamps. Circuit Z1 provides ground for the
combination flasher.
Circuit L5 from the flasher connects to the multi-
function switch to supply power to the turn signals.
The multi-function switch supplies voltage to the
turn signals and side marker lamps on circuits L60
and L61.
Circuit L12 from the flasher connects to the multi-
function switch to supply power to the hazard flasher
circuits. The multi-function switch connects to the
turn signal and side marker lamps on circuits L60
and L61.
TURN SIGNALS
When the operator selects the right turn signal, the
multi-function switch connects power from circuit L5
to circuit L60. Circuit L60 feeds the right front and
right rear turn signal lamps. Circuit L60 also splices
to power the right turn signal indicator lamp on the
instrument cluster.
When the operator selects the left turn signal, the
multi-function switch connects power from circuit L5
to circuit L61. Circuit L61 feeds the left front and
left rear turn signal lamp. Circuit L61 also splices to
power the left turn signal indicator lamp on the in-
strument cluster.
Circuit Z1 provides ground for the turn signal
lamps.
HELPFUL INFORMATION
²The turn signal lamps are the same lamps used
for the hazard flasher.
²Check fuse 6 in the PDC and fuse 8 in the fuse
block if the turn signals do not operate.
²Circuit F83 also connects to the heated rear win-
dow relay.
HAZARD FLASHERS
When the operator selects the hazard flashers, the
multi-function switch circuit L12 from the combina-
tion flasher to circuits L60 and L61.
Circuit L60 feeds the right front and right rear
turn signal lamp. Circuit L60 also splices to power
the right turn signal indicator lamp on the instru-
ment cluster.
Circuit L61 feeds the left front and left rear turn
signal lamp. Circuit L61 also splices to power the left
turn signal indicator lamp on the instrument cluster.
Circuit Z1 provides ground for the hazard flasher
lamps.
HELPFUL INFORMATION
²The hazard flasher lamps are the same lamps
used for the turn signals.
²Circuit L9 also connects to the stop lamp switch.

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
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
