  1. Ignition OFF, disconnect the X1 harness connector at the driver door lock/window switch.
  2. Test for less than 1 ohm between the ground circuit terminal 5 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 4 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 door lock/window switch.
  5. Ignition ON, observe the scan tool Driver LF Window Switch parameters while using the driver power window switch on the DDM. The parameter should change between Off/Up/Down/ Express Up /Express Down.

    • If greater than the specified range, test the ground circuit for an open/high resistance.
  8. 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.
