Driver Power Window Malfunction

  1. Ignition OFF, disconnect the X1 harness connector at the driver window switch.
  2. Test for less than 1 ohm between the ground circuit terminal 3 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 1 and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  4. Ignition OFF, connect the X1 harness connector at the driver window switch and disconnect the harness connector at the driver window motor.
  5. Test for less than 5 ohms between the control circuit terminal 1 and ground.
    • If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the driver window switch.
  6. Test for less than 5 ohms between the control circuit terminal 2 and ground.
    • If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the driver window switch.
  7. Connect a test lamp between the control circuit terminal 1 and control circuit terminal 2.
  8. Command the driver window UP and DOWN by using the driver window switch. The test lamp should illuminate when commanding the UP and DOWN states.
    • If the test lamp remains OFF during either of the commands, test either control circuit for a short to ground. If the circuits test normal, replace the driver window switch.
  9. If all circuits test normal, test or replace the driver window motor.
