Wiper/Washer System: Testing

  1. Unplug wiper motor connector at motor. Check for battery voltage at Violet/Black wire. Move wiper switch to lower speed position. Voltage should be present at Black/White wire.
  2. If voltage is present and motor is properly grounded, wiper motor should operate. If motor fails to operate, it is defective. Check fuses and wiring if no voltage is present.
