Driver Window Malfunction

WARNING: This page is about a different car, the 2009 GMC Sierra, 2009 GMC Cab & Chassis Sierra, 2009 Chevrolet Silverado, and 2009 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the X1 harness connector at the DDS.
  2. Test for less than 1 ohm between the ground circuit terminal 6 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 2 and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  4. Verify that a test lamp illuminates between the B+ circuit terminal 4 and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  5. Ignition OFF, connect the X1 harness connector at the DDS.
  6. Ignition ON, observe the scan tool Driver Window Switch parameters while using the driver power window switch. The parameter should change between Off, Up, Down and Express Down.
    • If the parameter does not change, replace the DDS
  7. Ignition OFF, disconnect the harness connector at the driver window motor.
  8. Connect a test lamp between the control circuit terminal A and control circuit terminal B.
  9. Ignition ON, 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 is always OFF during either of the commands, test either control circuit for a short to ground or open/high resistance. If the circuits test normal, replace the DDS
    • If the test lamp is always ON, test either control for a short to voltage. If the circuits test normal, replace the DDS
  10. If all circuits test normal, test or replace the driver window motor.
