DESCRIPTION AND OPERATION (Continued)
tent wipe relay to switch from its normally grounded
position and connect circuit A5 to circuit V5. The A5
circuit is protected by a 40 amp fuse located in cavity
14 of the PDC.
The V5 circuit is connected to the HI/LOW Wiper
relay low speed side. Voltage is passed through the
relay to circuit V3, then to the LOW speed side of the
wiper motor. Ground for the wiper motor is provided
on circuit Z1.
If after the MIST switch is released and the wiper
control switch is no longer in the OFF position, the
wipers will enter the mode indicated by the wiper
control switch.
As the windshield wiper motor turns, the park
switch internal to the motor moves from its grounded
position to the open RUN position. The BCM uses
input from the park switch, on circuit V55, for wiper
position and system operation.
LOW SPEED OPERATION
When the LOW speed switch is activated a multi-
plexed signal is sent to the Body Control Module
(BCM) on circuit V52. The BCM then turns the wip-
ers ON LOW speed by providing a ground path for
circuit V14. This causes the intermittent wipe relay
to switch from its normally grounded position and
connect circuit A5 to circuit V5. The A5 circuit is pro-
tected by a 40 amp fuse located in cavity 14 of the
PDC.
The V5 circuit is connected to the HI/LOW Wiper
relay low speed side. Voltage is passed through the
relay to circuit V3, then to the LOW speed side of the
wiper motor. Ground for the wiper motor is provided
on circuit Z1.
As the windshield wiper motor turns, the park
switch internal to the motor moves from its grounded
position to the open RUN position. The BCM uses
input from the park switch, on circuit V55, for wiper
position and system operation.
HI SPEED OPERATION
When HIGH speed operation is selected, a multi-
plexed signal is sent to the Body Control Module
(BCM) on circuit V52. The BCM then turns the wip-
ers ON by grounding the V14 and V16 circuits.
By grounding the V14 circuit the intermittent
wiper relay is switched from its normally grounded
position to connect circuits A5 and V5. The A5 cir-
cuit, which originates in the PDC and is protected by
a 40 amp fuse located in cavity 14, then supplies
power to the HI/LOW wiper relay through circuit V5.
When the V16 circuit is grounded the HI/LOW
relay switches, from its normal position of LOW
speed, to the HIGH speed contact. Power for the coil
side of the relay is supplied by the F13 circuit. This
8W - 53 WIPERS
circuit also is the feed for the wiper switch and the
intermittent wiper relay.
Power for the windshield wiper motor is supplied
from the HI/LOW wiper relay to the motor on circuit
V4. Ground for the wiper motor is provided on circuit
Z1.
As the windshield wiper motor turns, the park
switch internal to the motor moves from its grounded
position to the open RUN position. The BCM uses
input from the park switch, on circuit V55, for wiper
position and system operation.
WASHER OPERATION
When the operator presses the WASH switch
power is supplied on the F13 circuit, through the
CLOSED switch contacts, to circuit V10. The V10 cir-
cuit is spliced and conects to the Body Control Mod-
ule (BCM) and the windshield washer pump motor.
The pump motor, which is located in the washer fluid
reservoir, is grounded at the right frame rail.
HELPFUL INFORMATION
• Check the 10 amp fuse located in cavity 15 of
the junction block
• Check the 40 amp fuse located in cavity 14 of
the PDC
• Check for a good ground at the instrument panel
left side cowl
• Check for a good ground at the right frame rail
