Wiper Function
The windshield wipers are driven by a single motor. Any wiper function generates
a Headlamp On signal from the Master Controller. To disengage automatic head-
light illumination, turn off the ignition, or activate and then deactivate the dash-
board headlamp switch.
Marker Flashlamp:
Pressing Marker Flashlamp causes the taillights and all marker
lights to momentarily flash.
OFF:
Cancels all wiper operations. Wiper function is also cancelled
when the ignition is turned off.
HI-LO:
When the button is pressed, wipers activate on low speed. If the button
is pressed again, the high wiper speed setting is activated. Subsequently
pressing the HI-LO button will alternate wiper operation between low
and high speed mode.
Wiper Wash:
Activates the wash pump relay while the button is pressed. If no
wiper function has been selected, the low wiper will activate
for a period of approximately three wiper cycles, after the
switch is released. If any wiper functions have been selected, the
wipers will continue to run in the selected mode after the wash
button is released.
Wiper Variable:
Operation of the Wiper Variable button causes the low speed wiper
function to activate for one wipe. If the button is pressed again within
approximately 30 seconds, the low speed wiper function activates again
and repeats at an interval determined by the time between the last two
operations of the button. Additional button operations will shorten the
cycle. Activating other wiper modes cancels the variable mode.
An example: In light rain or misting conditions, press the button once to initially clear the
windshield. If the windshield requires a second clearing, press the button again, setting the
timed interval between subsequent wipes required by the current conditions. To extend the
wipe interval, press the intermittent button twice more, or switch the wipers off and use the
same method to set the desired interval.
