Solution
1. Preparation
  • Gather necessary tools and components.
  • Disconnect the negative battery terminal to prevent electrical shorts.
  • Make sure the vehicle is parked in a well-lit area for visibility.
2. Inspect Light Switch Setting
  • Locate the interior light switch (usually on the overhead console).
  • Toggle the switch between “ON,” “OFF,” and “DOOR” positions.
  • Ensure that the setting is correct for normal operation.
3. Check Door Switches
  • Open each door and locate the door switch (usually on the door jamb).
  • Manually press the switch to see if the interior lights turn off.
  • If the switch does not respond, it may be stuck or defective; replace if necessary.
4. Test Voltage at Door Switch Connectors
  • Reconnect the negative battery terminal.
  • Set the multimeter to DC voltage.
  • Disconnect the connector from the door switch and test for voltage while the door is open and closed.
  • If voltage is detected with the door closed, the switch is malfunctioning.
5. Inspect the Interior Light Relay
  • Locate the interior light relay in the fuse box (refer to the owner's manual for exact location).
  • Remove the relay and inspect for signs of damage or corrosion.
  • Replace the relay if it appears defective.
6. Reinstall Components and Test
  • Reassemble any removed components.
  • Reconnect the negative battery terminal.
  • Test the interior lights by opening and closing the doors and toggling the light switch.
