Circuit F32 in the Power Distribution Center
(PDC) feeds the stop lamps. Circuit F32 connects to
the stop lamp switch. A 15 amp fuse in the PDC pro-
tects circuit F32.
When the operator presses the brake pedal, the
stop lamp switch CLOSES and connects circuit F32
to circuit L50. Circuit L50 connects to the stop
lamps. Circuit L50 also splices to power the CHMSL
lamp.
GROUND CIRCUIT
Circuit Z1 provides ground for the stop lamps,
CHMSL lamp, and the stop lamp switch. The Z1 cir-
cuit has more than one grounding point. It also sup-
plies ground path for the tail lamps, parking lamps,
headlamps, side marker lamps, rear license plate
lamp, back-up lamps and turn signals.
HELPFUL INFORMATION
²Check for blown fuses in circuit F32 (in PDC).
²Check for continuity across the stop lamp switch
when it is CLOSED.
²For rear lighting on the left side of the vehicle,
the Z1 circuit grounding point is in the left rear
wheel well.
²For rear lighting on the right side of the vehicle,
the Z1 circuit grounding point is in the right rear
wheel well.
²For the stop lamp switch, the Z1 circuit ground-
ing point is in the left front inner fender shield.
BACK-UP LAMPS
In the RUN position, the ignition switch connects
circuit A2 from the Power Distribution Center (PDC)to circuit A22. Circuit A22 feeds a bus bar in the fuse
block. A 40 amp fuse in the PDC protects the A2 and
A22 circuits.
Circuit F20 is one of four circuits that connects to
the fuse block bus bar fed by circuit A22. Circuit F20
supplies power to the back-up lamp switch. On 3±spd
automatic transaxle vehicles, the back-up lamp
switch is part of an assembly that includes the park/
neutral position switch.
When the operator puts the transmission in
REVERSE, the back-up lamp switch connects circuit
F20 to circuit L1. Circuit L1 feeds the back-up lamps.
A 10 amp fuse, in cavity 8 of the fuse block, protects
F20 and L1 circuits.
GROUND CIRCUIT
Circuit Z1 provides ground for the back-up lamps.
The Z1 circuit has more than one grounding point. It
also supplies ground path for the tail lamps, parking
lamps, headlamps, side marker lamps, rear license
plate lamp, stop lamps and turn signals.
HELPFUL INFORMATION
²Check for blown fuses in circuits A2 and F20.
²Check for continuity across the stop lamp switch
when it is CLOSED.
²For rear lighting on the left side of the vehicle,
the Z1 circuit grounding point is in the left rear
wheel well.
²For rear lighting on the right side of the vehicle,
the Z1 circuit grounding point is in the right rear
wheel well.
²Circuit F20 feeds the heated rear window switch
and A/C clutch cycling switch.

DESCRIPTION AND OPERATION
POWER WINDOWS
The power window system is supplied power from
the 30 amp circuit breaker located behind the fuse
block. Power for the circuit breaker is supplied on
circuit A22 from the ignition switch. This circuit is
HOT when the ignition switch is in the RUN posi-
tion.
Power for the A22 circuit is supplied by the A2 cir-
cuit which is HOT at all times and protected by a
40-amp fuse located in the Power Distribution Center
(PDC). The A22 is spliced and supplies power for the
fuses that protect the Airbag, A/C-Heater blower
motor, turn signals, and the heated rear window.
Circuit F21 connects, from the circuit breaker, to
both window switches. This is the feed for the
switches. Both switches use a BUS bar to provide
power for the different functions of the switch.
The ground path for the system is through master
window switch on the Z8 circuit. The grounding point
is located at the instrument panel left center support
brace.
MASTER WINDOW SWITCH (LEFT WINDOW
OPERATION)
When the window switch is moved to the window
DOWN position, voltage is supplied on the F21 cir-
cuit through the CLOSED contacts in the switch to
the Q21 circuit. The Q21 circuit connects from the
switch to the left front window motor. Grounding is
provided on circuit Q11 from the motor back to the
switch. The ground is passed through the switch to
the Z8 circuit. The Z8 circuit goes to its grounding
point.
When window UP operation is selected, the power
and ground circuits are reversed. Circuit Q11 is the
feed and circuit Q21 is the ground.
MASTER WINDOW SWITCH (RIGHT WINDOW
OPERATION)
When the window switch is moved to the window
DOWN position, voltage is supplied on the F21 cir-
cuit through the CLOSED contacts in the switch to
the Q26 circuit. The Q26 circuit connects from the
master switch to the right window switch. A BUS barinternal to the right switch passes the voltage
through the switch to circuit Q22. Circuit Q22 con-
nects from the switch to the right window motor.
Grounding is provided on circuit Q12 from the motor
back to the right switch.
The ground is passed through the switch on a BUS
bar to circuit Q16. Circuit Q16 then goes to the mas-
ter switch. The ground is passed through the switch
to the Z8 circuit. The Z8 circuit attaches to its
grounding point.
When window UP operation is selected, the power
and ground circuits are reversed. Circuits Q12 and
Q16 are the feeds and circuits Q22 and Q26 are the
grounds.
RIGHT WINDOW SWITCH OPERATION
When the window switch is moved to the window
DOWN position, voltage is supplied on the F21 cir-
cuit through the CLOSED contacts in the switch to
the Q22 circuit. The Q22 circuit connects from the
switch to the right front window motor. Grounding is
provided on circuit Q12 from the motor back to the
switch. The ground is passed through the switch to
the Q16 circuit. The Q16 circuit connects from the
right switch to the master switch. Ground is passed
through the master switch to the Z8 circuit. The Z8
circuit goes to its grounding point.
When window UP operation is selected, the power
and ground circuits are reversed. Circuit Q12 is the
feed and circuit Q22 is the ground.
HELPFUL INFORMATION
²Check the 40 amp fuse located in the PDC.
²Check the 30 amp circuit breaker located behind
the fuse block.
²Check the ground at the instrument panel left
center support.
