JEEP CHEROKEE 1995 Service Repair Manual

through this switch to circuit Q22. The Q22 circuit
then goes to the right rear window motor.
Ground for the window motor is supplied on the
Q12 circuit back to the right rear door switch. Circu-
ity internal to the switch then passes the ground to
circuit Q28. Circuit Q28 goes from the right rear door
switch to the master switch. A bus bar, internal to
the switch, connects the Q28 circuit to the Z1 circuit.
For window UP operation the circuits are reversed.
Circuits Q28 and Q12 are the feeds, and circuits Q22,
Q33 and Q18 are the grounds.
If the switch is being operated from the RIGHT
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 back to the master switch on
circuit Q28. A bus bar, internal to the switch, con-
nects the Q28 circuit to the Z1 circuit.
For window UP operation, the circuits are reversed.
Circuit Q12 is the power and circuit Q22 is the
ground.HELPFUL INFORMATION
²When the ignition switch is in the RUN position, it
connects circuit A1 from fuse 11 in the Power Distri-
bution Center (PDC) to circuit A38.
²Refer to the appropriate group of the Service Man-
ual for test procedures.

POWER DOOR LOCKS
POWER DOOR LOCKS
Two relays provide power for the power door lock
motors. The Unlock relay provides power for the un-
lock circuits while the Lock relay powers the lock cir-
cuits. Either the power door lock switches or the
remote keyless entry module operate the Unlock and
Lock relays.
LOCK RELAY
Circuit M1 from fuse 9 in the fuse block powers cir-
cuit P38. When either power door lock switch is put
in the LOCK position, the switch connects circuit P38
to circuit P35. If the operator uses Remote Keyless
Entry (RKE), the RKE module powers circuit P35. In
either case, circuit P35 supplies power to the coil side
of the lock relay, causing the relay contacts to close.
Circuit Z1 provides ground for the coil side of the
lock relay.
When the lock relay contacts close, they connect
battery voltage from circuit P37 to circuit P2. Circuit
P2 then supplies battery voltage to the power door
lock motors to LOCK the doors.
When the power doors LOCK, ground for the mo-
tors is on circuit P34 through the normally closed
contacts in the door unlock relay to ground on circuit
Z1.
UNLOCK RELAY
Circuit M1 from fuse 9 in the fuse block powers cir-
cuit P38. When either power door lock switch is put
in the UNLOCK position, the switch connects circuit
P38 to circuit P36. If the operator uses Remote Key-
less Entry (RKE), the RKE module powers circuit
P36. In either case, circuit P36 supplies power to the
coil side of the unlock relay, causing the relay con-
tacts to close. Circuit Z1 provides ground for the coil
side of the unlock relay.
When the unlock relay contacts close, they connect
battery voltage from circuit P37 to circuit P34. Cir-
cuit P34 then supplies battery voltage to the power
door lock motors to UNLOCK the doors.
When the power doors UNLOCK, ground for the
motors is on circuit P2 through the normally closed
contacts in the door lock relay to ground on circuit
Z1.
REMOTE KEYLESS ENTRY MODULE
Circuit M1 from the ignition off draw (IOD) fuse in
cavity 9 of the fuse block supplies power to the Re-
mote Keyless Entry (RKE) module. Circuit F87 from
fuse 17 in the fuse block supplies power to the RKE
module when the ignition switch is in the START or
RUN position. Circuit Z1 provides ground for the
RKE module.
The RKE module UNLOCKS the doors by energiz-
ing the unlock relay on circuit P36. Refer to Unlock
Relay.
The module LOCKS the doors by energizing the
lock relay on circuit P35. Refer to Lock Relay.
HELPFUL INFORMATION
²Fuse 13 in the fuse block powers circuit P37. Cir-
cuit A7 from fuse 3 in the PDC feeds fuse 13 in the
fuse block.
²Circuit A7 from fuse 3 in the PDC also feeds fuse
16 in the PDC. PDC fuse 16 powers fuse 9 in the
fuse block. Fuse 9 protects the M1 circuit.

POWER MIRRORS
POWER MIRRORS
Four switches operates the left and right power
mirrors. One switch selects right or left mirror. Each
mirror has two motors; a LEFT/RIGHT motor and a
UP/DOWN motor. The motors switch polarity to al-
low mirror adjustment.
Circuit A7 from fuse 3 in the Power Distribution
Center (PDC) supplies battery voltage to fuse 16 in
the PDC. Fuse 16 in the PDC supplies voltage to the
Ignition Off Draw (IOD) fuse (fuse 9) in the fuse
block. Fuse 9 supplies power to circuit M1. Circuit
M1 connects to circuit P38. Circuit P38 powers the
power mirror switch. Circuit Z1 connects to the
power mirror switch and supplies ground for the
power mirror system.
RIGHT POWER MIRROR OPERATION
In the right position, the power mirror switch sup-
plies power to the right mirror LEFT/RIGHT motor
on circuit P79 when a rightward adjustment is made.
Circuit P77 provides the ground path the for right-
ward adjustments.
When the operator makes leftward adjustment, po-
larity reverses. For leftward adjustments, the switch
supplies battery voltage to the right mirror LEFT/
RIGHT motor on circuit P77. Circuit P79 supplies
ground for leftward adjustments.
During upward adjustments, the switch supplies
voltage to the right mirror UP/DOWN motor on cir-
cuit P79. Circuit P78 supplies ground during upward
adjustments.
For downward adjustments, the polarity is re-
versed, the switch powers the right mirror UP/
DOWN motor on circuit P78. Circuit P79 supplies the
ground path.
LEFT POWER MIRROR OPERATION
In the left position, the power mirror switch sup-
plies power to the left mirror LEFT/RIGHT motor on
circuit P79 when a rightward adjustment is made.
Circuit P81 provides the ground path the for right-
ward adjustments.
When the operator makes leftward adjustment, po-
larity reverses. For leftward adjustments, the switch
supplies battery voltage the left mirror LEFT/RIGHT
motor on circuit P81. Circuit P79 supplies ground for
leftward adjustments.
During upward adjustments, the switch supplies
voltage to the left mirror UP/DOWN motor on circuit
P79. Circuit P80 supplies ground during upward ad-
justments.
For downward adjustments, the polarity is re-
versed, the switch powers the left mirror UP/DOWN
motor on circuit P80. Circuit P79 supplies the ground
path.
