Downloaded from www.Manualslib.com manuals search engine STOP LAMPS
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

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.
