Solution

1. Preparation

Gather tools (screwdrivers, multimeter, OBD-II scanner).
Ensure the vehicle is in park and ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Door Switches

Sub-steps:
- Locate each door switch (usually found on the door frame).
- Remove the switch from the door frame (if necessary) by unscrewing or unclipping it.
- Test the switch with a multimeter to ensure it opens/closes as the door is operated.
- Clean the switch contacts if they appear dirty or corroded.
- Reinstall the switches and reconnect any connectors.

3. Check Interior Lighting Control Settings

Sub-steps:
- Turn on the ignition without starting the engine.
- Navigate to the vehicle settings on the dashboard display.
- Locate the interior light settings and ensure they are set to the desired mode (e.g., "door" or "off").
- Adjust settings if needed and exit the menu.

4. Test the Interior Light Switch

Sub-steps:
- Locate the interior light switch (usually near the overhead console).
- Remove the switch and inspect for any physical damage.
- Use a multimeter to check continuity of the switch in both positions (on/off).
- Replace the switch if it fails the continuity test.

5. Reconnect Battery and Test

Sub-steps:
- Reconnect the negative battery terminal.
- Start the vehicle and test the interior lights by opening and closing the doors.
- Confirm that the lights operate correctly based on door position and switch settings.
