Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, screwdriver set, and a flashlight.
Ensure the vehicle is parked on a flat surface and the ignition is turned off before starting work.

2. Inspect and Test Door Switches

Sub-steps:
- Locate the door switches, typically found on the door jamb.
- Manually press each door switch to see if the lights turn off.
- If a switch is stuck or not functioning, consider replacing it.

3. Check Lighting Control Settings

Sub-steps:
- Turn the ignition to the ON position.
- Navigate to the lighting controls on the dashboard.
- Confirm that the interior lights are not set to the "always on" position.
- Adjust settings as necessary and observe if the lights turn off.

4. Test and Replace Fuse if Necessary

Sub-steps:
- Locate the fuse box (refer to the owner's manual for exact location).
- Use a multimeter to check for continuity on the interior light fuse.
- If the fuse is blown, replace it with a new one of the same amperage rating (typically 10A or 15A).
- Reassemble the fuse box cover securely.

5. Inspect Wiring and Connectors

Sub-steps:
- Visually inspect the wiring harness connected to the interior lights and door switches.
- Look for any frayed wires, corrosion, or loose connections.
- Repair or replace any damaged wiring or connectors as necessary.
