Windshield Washer Pump Circuit Test

  1. Ignition OFF, disconnect the harness connector at the windshield washer fluid pump.
  2. Test for less than 1 ohm of resistance between the ground circuit terminal 1 and ground.
    • If greater than 1 ohm, repair the ground circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates between the washer pump control circuit terminal 2 and ground while pressing the washer switch.
    • If the test lamp does not illuminate, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the underhood fuse block.
  4. If all the circuits test normal, replace the windshield washer fluid pump.
