Solution

1. Preparation

Gather all necessary tools and parts.
Tools required:
- Screwdriver set
- Multimeter
- OBD-II scanner
- Torque wrench (if applicable)
Safety warnings:
- Disconnect the battery before working on electrical systems.

2. Inspect Door Latches

Open each door and inspect the latch mechanism.
Ensure that the latch is clean and free of debris.
Manually push the latch to see if the interior lights turn off; this indicates a faulty latch mechanism.

3. Test and Replace Door Switches

Locate the door switches for each door (typically found in the door frame).
Use a multimeter to check for continuity:
- Disconnect the door switch connector.
- Set the multimeter to the continuity setting.
- Press the switch and check for continuity; it should show a reading when pressed.
If a switch is faulty, replace it with a new part.
- Remove the old switch by unscrewing it and disconnecting the wiring harness.
- Install the new switch and secure it in place.

4. Check Interior Light Switch

Locate the interior light switch, usually found on the overhead console.
Ensure it is in the correct position (not in the "ON" position).
If malfunctioning, replace the switch by removing the console cover and disconnecting the wiring.

5. Reconnect Battery and Test

Reconnect the battery and check if the interior lights operate correctly.
Test each door to confirm that the lights turn off when the doors are closed.
