OPERATION
N08KHAC
Wiper Low-speed and High-speed Operation
l
When the wiper switch is at "1" with the
ignition switch at either "ACC" or "ON", current
flows through fuse No. IO, wiper motor (low-
speed brush), wiper switch and ground; the
wipers operate at low speed.
l
When the wiper switch is at "2", current flows
through fuse No. 10, wiper motor (high-speed
brush), wiper switch, and ground; the wipers
operate at high speed.
Wiper Automatic Stopping Operation
l
When the wiper switch is set at "OFF'. position
to stop the wipers, current flows through the
wiper motor (low-speed brush), wiper switch,
wiper relay (contacts) wiper motor (cam con-
tacts), and ground, causing the wiper motor to
continue operation until the wiper blades return
to their park positions.
l
Once the wiper blades have reached park
positions, the wiper motor cam moves to open
its contacts, This interrupts flow of current to
ground, and the wiper motor stops.
Washer Operation
When the washer switch is "ON", with the ignition
switch in either "ACC" or "ON", current flows
through fuse No. 10, washer motor, washer switch,
and ground; the washer motor operates.
Washer Fluid Level Indicator Light
When the washer fluid level drops below the preset
level while the ignition switch at "ON", the washer
fluid level sensor closes its contacts, causing
current to flow through fuse No. 13, washer fluid
level sensor, and ground, and in turn, the washer
fluid level indicator light goes on.
For the operation of the intermittent wipers and
washer-interlocked wipers, refer to the "ETACS"
section.
