        Component without harness connected

        (Windshield Wiper Motor Assembly)

        Check low speed operation.

        Connect a battery positive (+) lead to terminal 5 (+1) and a negative (-) lead to terminal 4 (E), and check that the motor operates at low speed.

        OK
        Motor operates at low speed.

      3. Check high speed operation.

        Connect a battery positive (+) lead to terminal 3 (+2) and a negative (-) lead to terminal 4 (E), and check that the motor operates at high speed.

        OK
        Motor operates at high speed.
