Solution

1. Preparation

Gather tools: screwdriver set, multimeter, OBD-II scanner.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect Door Switches

Locate the door switches on each door frame.
Remove the door panel if necessary to access the switch directly.
Use the multimeter to check continuity across the switch when the door is closed.
- If the switch is faulty, replace it with a new one.
Reassemble the door panel and reconnect the battery.

3. Check Interior Light Switch

Locate the interior light switch, usually on the ceiling or dashboard.
Ensure it is set to the "Door" position; if it's stuck in the "ON" position, gently free it.
If the switch is damaged, replace it with a compatible part.

4. Test Body Control Module (BCM)

With the OBD-II scanner, check for any BCM-related codes.
If there are no codes but the lights remain on, consider resetting the BCM by disconnecting the battery for 10 minutes and reconnecting it.
If the issue persists, the BCM may need to be replaced.

5. Inspect Wiring and Ground Connections

Check the wiring harness that connects to the interior lights for any signs of damage or short circuits.
Ensure all ground connections are secure and free from corrosion.
Repair or replace damaged wiring as needed.
