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
HAZARD FLASHERS..................... 5TURN SIGNALS......................... 5
DESCRIPTION AND OPERATION
TURN SIGNALS
Voltage for the turn signals flows from the Power
Distribution Center (PDC) to the ignition switch on
circuit A2. With the key in the RUN position, the
ignition switch connects voltage from the A2 circuit
to the A22 circuit. A 40 amp fuse in the PDC protects
the A2 and A22 circuits.
Circuit A22 connects to a bus bar in the fuse block.
L5 is one of the circuits fed by the bus bar. Circuit
L5 contains a 10 amp fuse and supplies voltage to
the multi-function switch. The multi- function switch
supplies voltage to the combination flashing unit on
circuit L55. Voltage leaves the combination flashing
unit on circuit L32 and flows to the multi-function
switch connector.
RIGHT TURN SIGNAL
When the operator selects the right turn signal,
the multi-function connects power from circuit L32 to
circuits L60 and L62. Circuit L62 connects to the
multi-function switch and feeds the right rear turn
signal/hazard flasher/stop lamp.
Circuit L60 connects to the multi-function switch
and feeds the right front turn signal/hazard flasher
lamp and side marker lamp. Circuit L60 also splices
to power the turn signal indicator lamp on the
instrument cluster.
LEFT TURN SIGNAL
When the operator selects the left turn signal, the
multi-function connects power from circuit L32 to cir-
cuits L61 and L63. Circuit L63 connects to the multi-
function switch and feeds the left rear turn signal/
hazard flasher/stop lamp.
Circuit L61 connects to the multi-function switch
and feeds the left right front turn signal/hazard
flasher lamp and side marker lamp. Circuit L61 also
splices to power the turn signal indicator lamp on the
instrument cluster.
GROUND CIRCUIT
Circuit Z1 provides ground for all the turn signal
lamps, although the it has different grounding pointsfor each turn signal circuit. Circuit Z2 provides the
ground path for the combination flashing unit.
HELPFUL INFORMATION
²For the left front turn signal/hazard flasher
lamp, the Z1 circuit grounding point is the left side of
the radiator closure panel.
²For the right front turn signal/hazard flasher
lamp, the Z1 circuit grounding point is in the right
fender side shield.
²For the left rear turn signal/hazard flasher/stop
lamp, the Z1 circuit grounding point is in the left
rear wheel well.
²For the right rear turn signal/hazard flasher/
stop lamp, the Z1 circuit grounding point is in the
right rear wheel well.
²Circuit Z1 also supplies ground for the head-
lamps, parking lamps, rear license plate lamp,
back-up lamps and side marker lamps.
²The grounding point for circuit Z2 is the instru-
ment panel right center support. Circuit Z2 supplies
ground for the combination flashing unit.
²A 10 amp fuse, in cavity 6 of the fuse block, pro-
tects circuit L5.
²A 40 amp fuse in the PDC protects the A2 and
A22 circuits.
²The bus bar in the fuse block that connects to
circuit A22 and feeds circuit L5 for the turn signals
also powers three other fuse protected circuits. The
other circuits are C1, F20 and F25.
HAZARD FLASHERS
Circuit L9 from the Power Distribution Center
(PDC) supplies battery voltage for the hazard flash-
ers. A 10 amp fuse in the PDC protects circuit L9.
Circuit L9 connects to the multi-function switch.
With the hazard flashers ON, the multi-function
switch connects circuits L9 and L55.
Circuit L55 feeds the combination flashing unit.
Circuit Z2 provides ground for the flashing unit.
From the flashing unit, circuit L32 connects to the
multi-function switch. With the hazard flashers ON,
the multi-function switch connects circuit L32 to cir-
cuits L60, L61, L62, and L63.

DESCRIPTION AND OPERATION
HELPFUL INFORMATION.................. 4WIPERSÐINTERMITTENT................. 4
DESCRIPTION AND OPERATION
WIPERSÐINTERMITTENT
The intermittent windshield wiper system is pow-
ered by a 20 amp fuse located in the fuse block. This
fuse is HOT in the RUN and ACCESORY position.
This system has three modes of operation, INTER-
MITTENT, LOW, and HIGH.
When the ignition switch is in the RUN or ACCE-
SORY position, power is supplied on the F13 circuit
to the windshield wiper switch and wiper motor. The
wiper motor is case grounded and the switch logic
and relay control uses its own ground on the Z2 cir-
cuit to the right instrument panel center support.
When the operator moves the switch to LOW speed
position, battery voltage is passed through the switch
to circuit V3, which connects to the LOW speed
brushes of the wiper motor. If the switch is moved to
the HIGH speed mode of operation, power is
switched to the V4 circuit and to the HIGH speed
brushes of the motor.
When the delay mode of operation is selected cir-
cuits internal to the switch power up the logic and
relay control. The internal control supplies power to
the LOW speed area of the switch (V3 circuit) and
cycles the wipers. The amount of delay between
wiper cycles is dependent on switch position. All
relays and internal logic in the switch are not ser-
viceable and should be replaced as an assembly.As the windshield wiper motor turns, the park
switch internal to the motor moves from its grounded
position to the powered RUN position. When the
wiper switch is turned OFF, the V5 circuit is used to
prevent the wipers from stopping in any position but
park.
The intermittent windshield wiper system is also
equipped with a pulse wipe feature. To activate this
feature the operator presses the washer switch
momentarily. When the washer switch CLOSES, a
voltage signal is sent to the internal logic and relay
control. The control will cycle the wipers. In addition,
the wipers are placed in the maximum delay posi-
tion.
The windshield washer uses a pump motor inside
of the windshield washer fluid reservoir. When the
washer switch is pressed, power is supplied on the
V10 circuit to the pump motor. Ground for the pump
motor is the Z1 circuit and terminates at the left
headlamp ground.
HELPFUL INFORMATION
²Check the 20 amp fuse in cavity 15 of the fuse
block.
²Check the ground strap on the windshield wiper
motor.
²For the intermittent wiper system a ground is
dedicated to the wiper switch.
