Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the appropriate window motor.
  2. Connect a test lamp between control circuit terminal A and control circuit terminal B.
  3. Ignition ON, command the window UP and DOWN by using the door switch. The test lamp should turn ON when commanding the UP and DOWN states.
    • If the test lamp is always OFF during either of the commands, test for a short to ground or open/high resistance on either control circuit. If the circuits test normal, replace the door switch.
    • If the test lamp is always ON, test for a short to voltage on either control circuit. If the circuits test normal, replace the door switch
  4. If all circuits test normal, test or replace the window motor.
