er switch.
4. Low speed:
INSPECT WIPER MOTOR OPERATION
5
Connect the positive (+) lead from the battery to terminal 5 and
the negative (-) lead from the battery to the motor body or termi-
nal 4, and check that the motor operates at low speed.
If operation is not as specified, replace the motor.

5. High speed:
3 INSPECT WIPER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 3 and
the negative (-) lead from the battery to the motor body or termi-
nal 4, and check that the motor operates at high speed.
If operation is not as specified, replace the motor.

(c) Connect the positive (+) lead from the battery to terminal
2 and the negative (-) lead from the battery to the motor
body or terminal 4, and check that the motor stops run-
ning at the stop position after the motor operates again.
5 If operation is not as specified, replace the motor.

I01937
7. INSPECT WASHER MOTOR OPERATION
2
Connect the positive (+) lead from the battery to terminal 2 and
the negative (-) lead to terminal 1, and check that the motor op-
erates.
1 NOTICE:
These tests must be performed quickly (within 20 seconds)
to prevent the coil from burning out.
If operation is not as specified, replace the motor.
