Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to prevent electrical shock.
2. Inspect and Test Door Switches
  • Tools Required: Multimeter, screwdriver, flashlight
  • Locate the door switches (typically integrated into the door latch).
  • Remove any covers or panels to access the door switches.
  • Use a multimeter to test each switch:
    • Set the multimeter to continuity mode.
    • Connect the probes to the switch terminals; it should show continuity when the switch is pressed (door closed).
  • Replace any faulty switches.
3. Check Wiring and Connections
  • Visually inspect the wiring harness for frays or damage, especially near the door hinges.
  • If damage is found, repair or replace the affected wiring.
  • Ensure all connectors are securely fastened and free of corrosion.
4. Inspect the Interior Light Relay
  • Tools Required: Relay tester or multimeter
  • Locate the interior light relay in the fuse box (refer to the owner’s manual for exact location).
  • Test the relay for proper function using a relay tester; replace if faulty.
5. Reconnect Battery and Test
  • Reconnect the negative battery terminal.
  • Close all doors and observe if the interior lights turn off as expected.
