2. INSPECT INTERMITTENT OPERATION OF SWITCH
(a) Turn the wiper switch to INT position.
(b) Turn the INT switch to FAST position.(Variable type)
(c) Connect the positive (+) lead from the battery to termi-
nal 18 and the negative (±) lead to terminal 16.
(d) Connect the positive (+) lead from the voltmeter to ter-
minal 7 and the negative (±) lead to terminal 16, check
that the meter needle indicates battery voltage.
(e) After connecting terminal 4 to terminal 18, connect it to
terminal 16.
Then, check that the voltage rises from 0 volts to bat-
tery voltage with in the times as shown in the table.
3. INSPECT WASHER SWITCH OPERATION
(Washer linked type)
(a) Connect the positive (+) lead from the battery to ter-
minal 18 and the negative (±) lead to terminal 16.
(b) Connect the positive (+) lead from the voltmeter to
terminal 7 and the negative (±) lead to terminal 16.
(c) Push in the washer switch, check that the voltage
changes as shown in the table.
If operation is not as specified, replace the wiper and
washer switch.If operation is not as specified, replace the wiper and
washer switch.

Front Wiper Motor
INSPECTION OF MOTOR
1. INSPECT MOTOR OPERATES AT LOW SPEED
(a) Disconnect the connector from the wiper motor.
(b) Connect the positive (+) lead from the battery to
terminal 2. and the negative (±) lead to the motor
body.
(e) Check that the motor operates at low speed.
REPLACEMENT OF SWITCH
REPLACE SWITCH
(a) Disconnect terminals from the connector.
(See page BE± 16)
(b) Remove the wiper and washer switch.
(e) Install the wiper and washer switch.
(d) Install terminals to the connector.
(See page BE±1 7)
(c) Connect terminals 2 and 3.
(d) Connect the positive (+) lead from the battery to ter-
minal 4.
(e) Check that the motor stops running at the off position
after the motor operates again.
If operation is not as specified, replace the motor. 3. INSPECT MOTOR OPERATES, STOPPING AT STOP
POSITION
(a) Operate the motor at low speed.
(b) Stop motor operation anywhere except at the off
position by disconnecting terminal 2. 2. INSPECT MOTOR OPERATES AT HIGH SPEED
(a) Connect the positive (+) lead from the battery to ter-
minal 1 and the negative (±) lead to the motor body.
(b) Check that the motor operates at high speed.

INSPECTION OF MOTOR AND RELAY
1. INSPECT RELAY AND MOTOR OPERATES
(a) Connect the positive (+) lead from the battery to terminal
1 and negative (±) leads to both terminal 3 and
motor body.
(b) Check that the motor operates.
2. INSPECT INTERMITTENT OPERATION OF RELAY
(a) Connect the positive 1+y lead from the battery to ter-
minal 1 and negative t±) leads to both terminal 2 and
motor body.
(b) Check that the motor operates intermittently for 9
15 seconds.
If operation is not as specified, replace the relay.
3. INSPECT MOTOR OPERATES, STOPPING AT STOP
POSITION
(a) Start motor operation by connecting the positive (+j
lead from the battery to terminal 1 and the negative (±
lead to both terminal 3 and motor body.
