Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative terminal of the battery to avoid electrical shocks.

2. Inspect Door Switches

Locate the door switches in each door frame.
Remove the door panel if necessary to access the switch.
Test the door switch function with a multimeter: it should show continuity when the door is open and none when closed.
Clean or replace any defective switches.

3. Check Interior Light Switch

Locate the interior light switch, usually found near the overhead console.
Ensure the switch is set to "Door" mode; if it's stuck or malfunctioning, replace it.
If the switch operates correctly, reconnect the battery and test the lights.

4. Examine Fuses

Locate the fuse box, which is typically under the dashboard or in the engine compartment.
Identify the fuse for the interior lights (refer to the owner's manual).
Inspect the fuse for any visible damage; replace if blown.

5. Body Control Module (BCM) Reset

If the previous steps do not resolve the issue, consider resetting the BCM.
Reconnect the battery, then turn the ignition to the "ON" position without starting the engine for about 10 seconds.
Turn off the ignition and wait for a few minutes before starting the vehicle to reset any electronic glitches.
