Circuit/System Testing

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

Driver Window Malfunction

  1. Ignition OFF, disconnect the harness connector at the driver window switch.
  2. Test for less than 1 ohm between the ground circuit terminal P 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 RAP circuit terminal K and ground.
    • If the test lamp does not illuminate, test the RAP circuit for a short to ground or an open/high resistance.
  4. Ignition OFF, connect the harness connector at the driver window switch and disconnect the harness connector at the driver window motor.
  5. Test for less than 1 ohm 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, test or replace the driver window switch.
  6. Test for less than 1 ohm 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, test or replace the driver window switch.
  7. Connect a test lamp between control circuit terminal 1 and control circuit terminal 2.
  8. Ignition ON, command the driver door 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 does not illuminate during either of the commands, test both control circuits for a short to ground. If the circuits test normal, test or replace the driver window switch.
  9. If all circuits tests normal, test or replace the driver window motor.

Front Passenger Window Malfunction

  1. Ignition OFF, disconnect the harness connector at the driver window switch.

  3. Ignition OFF, connect the harness connector at the driver window switch and disconnect the harness connector at the front passenger window switch.
  4. Ignition ON, verify that a test lamp illuminates between the RAP circuit terminal B and ground.
    • If the test lamp does not illuminate, test the RAP circuit for an open/high resistance
  5. Ignition OFF, test for less than 1 ohm between the control circuit terminal A 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, test or replace the driver window switch.
  6. Test for less than 1 ohm between the control circuit terminal D 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, test or replace the driver window switch.
  7. Connect a test lamp between control circuit terminal A and control circuit terminal D.
  8. Ignition ON, command the front passenger door window UP and DOWN by operating the RF window switch on the driver master control. The test lamp should illuminate when commanding the UP and DOWN states.
    • If the test lamp does not illuminate during either of the commands, test both control circuits for a short to ground. If the circuits test normal, test or replace the driver window switch.
  9. Ignition OFF, connect the harness connector at the front passenger window switch and disconnect the harness connector at the front passenger window motor.
  10. Test for less than 1 ohm 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, test or replace the front passenger window switch.
  11. Test for less than 1 ohm 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, test or replace the front passenger window switch.
  12. Connect a test lamp between control circuit terminal 1 and control circuit terminal 2.
  13. Ignition ON, command the front passenger door window UP and DOWN using the passenger window switch. The test lamp should illuminate when commanding the UP and DOWN states.
    • If the test lamp does not illuminate during either of the commands, test either control circuit for a short to ground. If the circuits test normal, test or replace the front passenger window switch.
  14. If all circuits test normal, test or replace the front passenger window motor.

Rear Window Malfunction

  1. Ignition OFF, disconnect the harness connector at the driver window switch.
  2. Ignition ON, verify that a test lamp illuminates between the RAP circuit terminal G and ground.
    • If the test lamp does not illuminate, test the RAP circuit for an open/high resistance
  3. Ignition OFF, connect the harness connector at the driver window switch and disconnect the harness connector at the appropriate rear window switch.
  4. Ignition ON, with the lockout switch closed, verify that a test lamp illuminates between the control circuit terminal B and ground.
    • 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, test or replace the driver window switch.
  5. Ignition OFF, test for less than 1 ohm between the control circuit terminal D 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, test or replace the driver window switch.
  6. Test for less than 1 ohm between the control circuit terminal A 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, test or replace the driver window switch.
  7. Connect a test lamp between control circuit terminal A and control circuit terminal D.
  8. Ignition ON, command the rear passenger door window UP and DOWN using the window switch on the driver master control. The test lamp should illuminate when commanding the UP and DOWN states.
    • If the test lamp does not illuminate during either of the commands, test both control circuits for a short to ground. If the circuits test normal, test or replace the driver window switch.
