Front Wiper Motor

  1. Disconnect wiring connector from wiper motor. Turn ignition switch to "ON" position. Using a voltmeter, measure voltage between Blue terminal wire and ground. SeeFig 1 . If no voltage is present, check fuse or repair wiring harness. Using an ohmmeter, ensure continuity is present between "B" terminal wire and ground.
  2. Connect battery positive voltage to "B" terminal wire at motor connector. SeeFig 2 . Connect negative battery voltage to "A" terminal wire at motor connector. Motor should operate at low speed. Connect negative lead to "C" terminal of motor connector. Ensure motor operates at high speed.
