  3. Ignition OFF, test for less than 1.0 ohm of resistance between the control circuit terminal B 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.
  4. Ignition OFF, connect a test lamp between control circuit terminal A and control circuit terminal B.
  5. Ignition ON, command the driver window UP and DOWN by pressing the Driver Window 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 on either of the control circuits, if the circuit tests normal, test or replace the Driver Window switch.
