INSPECTION
Operation Check of Rear Wiper Motor
1. Check that the motor operates continuously when
12V is connected to the (a) terminal and ground
is connected to the (b) terminal of the motor.
2. Start the motor again.
Disconnect the ground from the (b) terminal, and
then connect the ground to the motor body im-
mediately. Check that the motor shaft reaches the
auto-stop position, and that there is conductivity
through the grounding of the motor body.
Note:
Be sure to re-install the rubber seal correctly.
Operation Check of Rear Washer Motor
1. Using a voltmeter, measure the voltage between
the (b) terminal and a body ground with the igni-
tion switch ON.
2. If no voltage, check the fuse or repair the harness.
3. If the (b) terminal voltage is 12 V, connect the (a)
terminal to a body ground.
4. If the washer motor does not operate, replace the
washer motor.
