Park Test
- Turn wipers on. Use ignition switch to stop wiper blades so blades are not in park position. Connect jumper wires as shown in illustration. See Figure . Wiper should run one full cycle and then park. If motor does not park or will not run to park position, replace motor.
- If motor stops, check windshield wiper manual control switch and wiring for continuity. If switch and wiring are okay and wiper does not stop in OFF or INT positions of switch, replace interval governor.
