Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shorts.
Tools Required:
- OBD-II scanner
- Multimeter
- Screwdrivers
- Socket set

2. Inspect Door Switches

Locate the door switches on each door frame.
Use a multimeter to test the continuity of each door switch.
- If a switch shows continuity when the door is closed, it is faulty and needs replacement.
Replace any faulty switches with new ones.

3. Check Interior Light Switch

Locate the interior light switch, typically found on the overhead console.
Ensure the switch is in the "Door" or "Off" position; adjust if necessary.
If the switch is faulty, replace it accordingly.

4. Inspect and Replace Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the fuse related to the interior lights (refer to the owner's manual for the exact location).
Use a fuse puller to extract the fuse and inspect it for damage.
- If blown, replace it with a fuse of the same amperage (usually 10-15 amps).

5. Check Body Control Module (BCM)

Inspect the BCM for any loose or damaged connections.
If necessary, reprogram or replace the BCM using a compatible OBD-II scanner or consult a professional technician.
