WINDSHIELD WIPER & WASHER
SWITCH
With the starter switch on, this switch controls wiper
motor operation and speed.
Both the washer and the
wiper motors operate while
the washer switch is on position.

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.
Nut 1. Windshield

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.

Replace the tank/motor when the result of inspection
is found abnormal.
