WIPER BLADE RUBBER
B REMOVAL
Fig. 8-278
1. Wiper blade
• Push the wiper blade lock while pulling the
wiper blade in the arrow direction. (Fig. 8-278)
W CAUTION:
When the wiper blade has been removed,wrap
the
tip of the wiper arm with cloth, to avoid
damaging the
glass.

HEADLIGHT WIPER/WASHER
GENERAL DESCRIPTION
The circuit consists of the starter switch, headlight wiper/washer switch, headlight wiper motor and washer
motor. By pushing the headlight wiper/washer switch, with the starter switch on, the wiper will make 5 strokes,
with washer solution applied between each of the first 4 strokes, regardless of the length of time the switch is
held down.
The washer nozzle is installed to the wiper blade, and the washer motor draws fluid from the same reservoir
as the windshield washer.
OPERATION OF HEADLIGHT WIPER
1. Headlight wiper switch is
set
to ON and headlight
wiper starts to operate.
