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

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. Ei

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.
