POWER WINDOWS
When the ignition switch is in the ACCESSORY or
RUN position, it connects circuit A1 from fuse 6 in
the Power Distribution Center (PDC) to circuit A48.
Circuit A48 powers circuit F81 through fuse 12 in the
fuse block. Circuit F81 supplies voltage to the power
window system.
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.
RIGHT FRONT WINDOW OPERATION
When the operator selects window DOWN opera-
tion power is supplied on the F81 circuit through the
switch to circuit Q12. Circuit Q12 goes from the
switch to the power window motor. Ground for the
motor is supplied on the Q22 circuit back to the
switch. A bus bar, internal to the switch, connects the
Q22 circuit to the Z1 circuit.
For window UP operation the circuits are reversed.
Circuit Q22 is the feed, and circuit Q12 is the
ground.
LEFT 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 left front door switch. Power is passed through
this switch to circuit Q21. The Q21 circuit then goes
to the right front window motor.
Ground for the window motor is supplied on the
Q11 circuit back to the right door switch. Circuity in-
ternal 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 Q11 are the feeds, and circuits Q21
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 Q21 circuit.Ground for the motor is supplied on the Q11 circuit
through the switch and back to the master switch on
circuit Q16. A bus bar, internal to the switch, con-
nects the Q16 circuit to the Z1 circuit.
For window UP operation, the circuits are reversed.
Circuit Q11 is the power and circuit Q21 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 Q22. The Q22
circuit then goes to the left rear window motor.
Ground for the window motor is supplied on the
Q12 circuit back to the left rear door switch. Circuity
internal to the switch then passes the ground to cir-
cuit 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 Q12 are the feeds, and circuits Q22
and Q17 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 Q27. Circuit Q27
connects to the master window switch. A bus bar, in-
ternal to the switch, connects the Q27 circuit to the
Z1 circuit.
For window UP operation, the circuits are reversed.
Circuit Q12 is the power and circuits Q22, and Q17
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. Power
is passed through this switch to circuit Q22. The Q22
circuit then goes to the right rear window motor.

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 power door lock switch can operate the
Unlock and Lock relays.
LOCK RELAY
Circuit A7 from fuse 3 in the Power Distribution
Center (PDC) powers circuits P37 and P38 through
fuse 6 in the fuse block. When either power door lock
switch is put in the LOCK position, the switch con-
nects circuit P38 to circuit P35. 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 A7 from fuse 3 in the Power Distribution
Center (PDC) powers circuits P37 and P38 through
fuse 6 in the fuse block. When either power door lock
switch is put in the UNLOCK position, the switch
connects circuit P38 to circuit P36. Circuit P36 sup-
plies power to the coil side of the unlock relay, caus-
ing the relay contacts 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.
