WINDSHIELD WIPER/WASHER AND REAR WIPER/WASHER
GENERAL DESCRIPTION
~ The circuit consists of the starter switch, wiper & washer switches, wiper motors, washer motors and inter­
mittent relays for both the windshield and some models the rear wipers.
When the
wiper & washer switch is turned on with the starter switch on, the battery voltage is applied to the
wiper motor to activate the wiper.
The washer
motor squirts glass cleaning fluid while the washer switch is being pushed. The intermittent relay
is used
to control motion of the wiper.
OPERATION OF WINDSHIELD WIPER MOTOR (When wiper & washer SW is at "LO" or ''I NT"
position)
1.Condition of wiper switch is just "ON" (Wiper motor is starting to operate)
2.Condition
of wiper motor is operating

1. Operation in low speed
With the motor connector terminal 2 lC-38l con­
nected
to the battery (+) terminal and the
connector3lC-38l
to the(-) terminal, check to see
if the motor rotates in low speed.
2. Operation in high speed
With the motor connector terminal 1 lC-38l con­
nected
to the battery (+) terminal and the
connector
3lC-38I to the(-) terminal, check to see
if the motor rotates in high speed.
3.
Stop operation
After stopping the windshield wiper in the
position on the
way by confirming the operation
at the
low speed in Item No.1.
When the connectors 2
lC-381 and 5 lC-381 are
connected,
while connecting the motor connector
terminal 6
IC-381 to the battery (+) terminal and
the connector 3
IC-381 to the H terminal, check
to see if the motor rotates at low speed and stops
at the auto-stop position.
Repair
or replace the motor when the results of
the above inspections are found abnormal.
B REMOVAL (FIG. 8-256)
Preparation: Disconnect the battery ground cable.

1.
Windshield wiper motor
• Disconnect the connector.
• Remove 4 mounting bolts.
•
Remove the nut of the wiper motor shaft, and
disconnect the
linkage.
\f CAUTION:
To facilitate the removal of the nuts, be sure to
put out the tip portion of the linkage sufficiently
through the mounting hole of the motor by
sliding the wiper blade slowly.
B INSTALLATION
To install, follow the removal steps in the reverse
order, noting the
following points.
1. Tighten the wiper motor shaft nuts to the specified
torque.
Nut torque N·m (lb·in)j 14 (122)
2. Remove the wiper arms on both sides, and rotate
the
wiper motor until it get to the auto-stop
position
to reinstall the wiper blade.

With the battery(+)
terminal connected to the washer
motor connector terminal1 I C-351 and the(-) terminal
to the connector 2 IC-351, check to see if the cleaning
fluid
gushes out. (Fig. 8-257)
Replace the tank/motor when the result of inspection
is found abnormal.

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.
