Park Testing

  1. Stop wiper blades with ignition switch so that wiper blades are not in Park position. Connect jumper wires. See Fig 1 and Fig 2 . Wiper should run one full cycle and then park. If motor will not park or will not run to Park position, replace motor.
  2. 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 interval setting, replace interval governor.
