Wiperffasher (contd)
- How the Circuit Works
When the ignition switch is in ON (ll) or START (lll),
battery voltage is applied to lhe windshield
wiper/washer switch, and the windshield wiper
motor.
Low Speed
When you turn the wiper switch to LO, the wiper
motor's low speed winding is grounded through the
BLU wire and the LO speed contacts of the wiper
switch at G401, and the wipers run at low speed.
ParUOfi
When you turn the wiper switch OFF, the integrated
control unit (PARK input) grounds the wiper motor
through the BLUMHT wire. The cam switch on the
motor signals the integrated control unit that the
wipers are in the PARK position; the control unit
then removes ground from the motor, and the
wipers stop in the PARK position.
High Speed
When the wiper switch is in Hl, the high speed
windings ol the windshield wiper motor are
grounded through the BLUI/EL wire and the Hl
contacts of the wiper switch at G401 , and the
wipers run at high speed.
Intermittent
When the wiper switch is in lNT, battery voltage is
applied through the YEUBLU wire to the integrated
control unit (lntermittent wiper ON input). The
integrated control unit (lntermittenvPark Wiper
Control) grounds the low speed windings of the
wiper motor and the wipers make a single sweep
every few seconds (See Low Speed above). When
the wiper returns to the PARK position, the park
switch applies battery voltage through the
BLUMHT wire to the integrated control unit (PARK
input), and the wipers stop in the PARK position.
91-2
Mist
When you pull the wiper switch down to MIST
position, the high speed windings of the wiper motor
are grounded through the BLU//EL wire and the
closed contacts of the mist switch at G401, and the
wipers make one pass across the windshield at high
speed. The PABKOFF tunction then takes over and
the wrpers stop in the PARK position.
Washer
When you pull the wiper switch toward you to turn on
the washer switch, battery voltage is applied to the
washer motor. The motor pumps fluid onto the
windshield until you release the lever. On models
with combined wiper/washer operation (Canada), the
integrated control unit (windshield washer ON input)
senses power al the BLI(GRN wire terminal and
runs the washer motor whenever the wioers run.
