JEEP CHEROKEE 1995 Service Repair Manual

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

TRAILER TOW
TRAILER TOW
The factory installed trailer tow system in this ve-
hicle uses three relays and a circuit breaker along
with the trailer tow wiring connector located below
the rear bumper.
Battery voltage for the trailer tow circuit breaker
and relays is supplied on circuit A11. This circuit is
HOT at all times and connects to the power accessory
tap in the fuse block. An in line 10 amp circuit pro-
tected breaker protects circuit A11 and the trailer
tow circuits. The trailer tow circuit breaker is located
in the left rear quarter panel.
STOP LAMP RELAY
Power for the coil side of the stop lamp relay is
supplied by circuit L50. This circuit connects to the
stop lamps. Ground for the coil side is supplied on
circuit Z1.
When the operator depresses the brake pedal, volt-
age flows through the coil of the relay to ground
causing the contacts in the relay to connect circuits
A11 and 95.
Circuit 95 connects to the left and right turn signal
relays. Voltage flows through the closed contacts in
the relays to the trailer tow connector.
RIGHT TURN RELAY
Power for the coil side of the right turn relay is
supplied by circuit L60. This circuit connects to the
right side turn signal lamps. Ground for the coil side
of the relay is supplied on circuit Z1.
When the operator turns the right turn signal ON,
power flows through the coil in the relay to ground
causing the contacts in the relay to switch from there
normally CLOSED position to connect circuits 94 and
L60.
Circuit 94 is the feed for the contact side of the re-
lay. Circuit L60 connects from the relay to the trailer
tow connector.
Circuit 94 is fed power through the normally
CLOSED side of the stop lamp relay and circuit A11.
The A11 circuit is HOT at all times and protected by
a 10 amp circuit breaker located in the left rear
quarter panel.
LEFT TURN RELAY
Power for the coil side of the left turn relay is sup-
plied by circuit L61. This circuit connects to the left
side turn signal lamps. Ground for the coil side of the
relay is supplied on circuit Z1.
When the operator turns the left turn signal ON,
power flows through the coil in the relay to ground
causing the contacts in the relay to switch from there
normally CLOSED position to connect circuits 94 and
L61.
Circuit 94 is the feed for the contact side of the re-
lay. Circuit L61 connects from the relay to the trailer
tow connector.
Circuit 94 is fed power through the normally
CLOSED side of the stop lamp relay and circuit A11.
The A11 circuit is HOT at all times and protected by
a 10 amp circuit breaker located in the right rear
quarter panel.

POWER WINDOWS
The power window system is powered by circuit F81
which connects to the accessory tap in the fuse block.
The accessory tap receives its feed from the ignition
switch on the A38 circuit. Circuit A38 is HOT when
the ignition switch is in the RUN position only.
Circuit F81 connects to the master window switch.
Circuit Z1 provides ground for the power windows.
A LOCK-OUT feature is provided on the driver's
door window switch. When this feature is engaged the
other windows in the system will not operate.
LEFT FRONT WINDOW OPERATION
When the operator selects window DOWN operation
power is supplied on the F81 circuit through the
switch to circuit Q11. Circuit Q11 goes from the
switch to the power window motor. Ground for the
motor is supplied on the Q21 circuit back to the
switch. A bus bar, internal to the switch, connects the
Q21 circuit to the Z1 circuit.
For window UP operation the circuits are reversed.
Circuit Q11 is the feed, and circuit Q21 is the ground.
RIGHT FRONT WINDOW OPERATION
When the DRIVER selects window DOWN opera-
tion, power is supplied on the F81 circuit through the
switch to circuit Q26.
Circuit Q26 goes from the drivers door switch to the
right front door switch. Power is passed through this
switch to circuit Q22. The Q22 circuit then goes to the
right front window motor.
Ground for the window motor is supplied on the
Q12 circuit back to the right door switch. Circuity
internal to the switch then passes the ground to
circuit Q16. Circuit Q16 goes from the right front
door switch to the master switch. A bus bar, internal
to the switch, connects the Q16 circuit to the Z1
circuit.
For window UP operation the circuits are reversed.
Circuits Q16 and Q12 are the feeds, and circuits Q22
and Q26 are the grounds.
If the switch is being operated from the PASSEN-
GER'S front door, and the operator is requesting win-
dow DOWN operation, power is supplied on the Q1
circuit from the driver's master switch circuit through
the switch to the Q22 circuit.Ground for the motor is supplied on the Q12 circuit
through the switch and back to the master switch on
circuit Q16. A bus bar, internal to the switch, connects
the Q16 circuit to the Z1 circuit.
For window UP operation, the circuits are reversed.
Circuit Q12 is the power and circuit Q22 is the
ground.
LEFT REAR WINDOW
When the DRIVER selects window DOWN opera-
tion power is supplied on the F81 circuit through the
switch to circuit Q17.
Circuit Q17 goes from the drivers door switch to the
left rear door power window switch. Power is passed
through the switch to circuit Q12. The Q12 circuit
then goes to the left rear window motor.
Ground for the window motor is supplied on the
Q22 circuit back to the left rear door switch. Circuity
internal to the switch then passes the ground to
circuit Q27. Circuit Q27 goes from the left rear door
switch to the master switch. A bus bar, internal to the
switch, connects the Q27 circuit to the Z1 circuit.
For window UP operation the circuits are reversed.
Circuits Q27, and Q22 are the feeds, and circuits Q12,
and Q12 are the grounds.
If the switch is being operated from the LEFT
REAR door, and the operator is requesting window
DOWN operation, power is supplied on the Q1 circuit
from the driver's master switch circuit through the
switch to the Q22 circuit.
Ground for the motor is supplied on the Q12 circuit
through the switch and to circuit Q17. Circuit Q17
connects to the master window switch. A bus bar,
internal to the switch, connects the Q17 circuit to the
Z1 circuit.
For window UP operation, the circuits are reversed.
Circuit Q12 is the power and circuits Q22, and Q27
are the grounds.
RIGHT REAR WINDOW
When the DRIVER selects window DOWN opera-
tion, power is supplied on the F81 circuit through the
switch to circuit Q18.
Circuit Q18 goes from the drivers door switch to the
right rear door window switch connector where it
changes to circuit Q33. Circuit Q33 connects to the
right rear door window switch. Power is passed
