DESCRIPTION AND OPERATION
TAIL LAMPS AND LICENSE LAMPS
Circuit A3 in the Power Distribution Center (PDC)
connects to a bus bar in the fuse block. One of the
four circuits powered by the bus bar is circuit F33. A
40 amp fuse in the PDC protects the A3 circuit. A 15
amp fuse, in cavity number 2 of the fuse block, pro-
tects the F33 circuit.
The headlamp switch has 3 positions, ON, PARK
(tail lamps) and OFF, plus a dimmer switch. When
the headlamp switch is in the PARK or ON position,
it connects circuit F33 to circuit L7. From the head-
lamp switch, circuit L7 branches to power the front
parking lamps, rear tail lamps, side marker lamps,
and rear license plate lamp.
GROUND CIRCUIT
Circuit Z1 provides ground for the tail lamps, park-
ing lamps, headlamps, side marker lamps, lamps and
rear license plate lamps although different grounding
points are used. Circuit Z1 also provides the ground
path for the headlamps, stop lamps and turn signals.
HELPFUL INFORMATION
²Check for a blown 40 amp fuse in the PDC.
²Check for a blown fuse in cavity 2 of the fuse
block
²For the left rear parking lamp, turn signal, side
marker lamp, and the rear license plate the Z1 cir-
cuit grounding point is in the left rear wheel well.
²For the right rear parking lamp, turn signal and
side marker lamp, the Z1 circuit grounding point is
in the right rear wheel well.
²Circuit L7 also feeds the radio, if equipped.
²When the headlamp switch is in the PARK or
ON position, the dimmer circuit, F33, connects to cir-
cuit E1. Circuit E1 powers the ash receiver lamp,
transmission range indicator lamp, instrument panel
cluster illumination lamps, HVAC control lamp,
heated rear window lamp, and radio lamp. A 4 amp
fuse, in cavity 12 of the fuse block, protects circuit
E1.
FOG LAMPS (REAR)
The rear fog lamps will operate only when the
headlamp switch is in the ON position.
Circuit A3 from the Power Distribution Center sup-
plies (PDC) voltage to a bus bar in the fuse block.
Circuit F61 is one of four circuits that the bus bar
feeds and is protected by a 20 amp fuse in cavity 4.
Circuit F61 connects to the rear fog lamp switch and
the front fog lamp relay.
The fog lamp switch contains a relay that supplies
voltage to the fog lamps. Circuit L2 from the multi-
function switch supplies voltage to the coil side of the
relay (only when the headlamps operate on LOW
beam). Circuit F61 supplies voltage to the contact
side of the relay. During LOW beam headlamp oper-
ation when the fog lamp switch contacts CLOSE, cir-
cuit F61 connects to circuit L38.
Circuit L38 feeds right and left fog lamp. Circuit
L38 also feeds the green L.E.D. in the switch that
illuminates during fog lamps operation.
When the headlamp switch is in the PARK or ON
position, circuit E1 from the headlamp switch sup-
plies voltage for circuit E2. Circuit E2 contains a 4
amp fuse in cavity 12 of the fuse block, and powers
the bulb in the fog lamp switch.
GROUND CIRCUIT
Although circuit Z1 provides the ground path for
the fog lamps, the circuit has different grounding
points for each lamp.
Circuit Z3 supplies the ground path for the fog
lamp switch. The grounding point for the headlamp
switch is the instrument panel left center support.
HELPFUL INFORMATION
²Circuit Z1 also supplies ground for side marker
lamps, turn signals, parking lamps and headlamps.
²Circuit A3 from the PDC supplies voltage to the
headlamp switch for circuit L2.
²Circuit F33 from the fuse block supplies voltage
to the headlamp switch for circuit E1. Circuit A3
from the PDC supplies voltage to a bus bar in the
fuse block that feeds the F33 circuit. Fuse 2, in the
fuse block, protects the F33 circuit.

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.
