Solution

1. Preparation

Gather tools: multimeter, screwdriver set, and OBD-II scanner.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to avoid any electrical shorts while working.

2. Inspect Door Alignment

Open each door and visually inspect for any misalignment that may prevent the door from fully closing.
Adjust the door hinges or latches if necessary to ensure proper closure.

3. Test Door Switches

Locate the door switches, typically found at the door jamb.
Use a multimeter to test continuity across each switch:
- Disconnect the wire connector from the switch.
- Set the multimeter to continuity mode.
- Press the switch; a beep indicates a functional switch.
Replace any faulty switches with new ones.

4. Check Interior Light Switch

Inspect the interior light switch to ensure it is set to the correct mode (door, on, off).
If the switch is stuck or malfunctioning, replace it accordingly.

5. Inspect Wiring Harness

Examine the wiring harness connected to the door switches for any visible damage or loose connections.
Repair or replace any damaged wiring or connectors.

6. Reconnect Battery and Test

Reconnect the battery after all checks and repairs.
Test the interior lights by closing all doors and observing functionality.
