Dome Lamp Switch Testing 

  1. Ignition OFF, disconnect the harness connector at the dome lamp switch.
  2. Test for infinite resistance between the three signal terminals with the switch being in the opposite position and the voltage supply terminal.
    • If less than infinite resistance, replace the dome lamp switch.
  3. Test for less than 2 ohms between each of the signal terminals with the switch in the appropriate position and the voltage supply terminal.
    • If greater than 2.1 ohms, replace the dome lamp switch.
    NOTE: This test can be performed on any of the door ajar switches

Door Ajar Switch Testing 

  1. Ignition OFF, disconnect the harness connector at the door ajar switch.
  2. Test for infinite resistance between the signal terminal and the voltage supply terminal with the switch in the open position.
    • If less than infinite resistance, replace the door ajar switch.
  3. Test for less than 1 ohms between the signal terminal and the voltage supply terminal with the switch in the closed position.
    • If greater than 1 ohms, replace the door ajar switch.
