Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, screwdriver set, and a flashlight.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect Door Switches

Locate the door switches (usually found on the door frame).
Tools Required: Screwdriver set
For each door, remove the switch and test it with a multimeter to ensure it opens and closes the circuit correctly.
If a switch is faulty, replace it with a new one.

3. Check Interior Light Switch

Locate the interior light switch, typically on the overhead console.
Ensure the switch is set to the "door" position.
If it is stuck or malfunctioning, replace it.

4. Examine Wiring and Connectors

Inspect the wiring harness leading to the interior lights for any signs of wear, damage, or loose connections.
Repair or replace any damaged wiring or connectors as necessary.

5. Body Control Module Inspection

Locate the body control module (BCM) in the vehicle, usually found under the dashboard or in the engine compartment.
Use the OBD-II scanner to check for fault codes.
If there are relevant codes, follow the manufacturer's instructions for troubleshooting or replacing the BCM.
