Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the battery to prevent electrical shock.

2. Inspect and Adjust Door Switches

Locate the door switches for each door; these are typically located in the door frame.
Clean any debris or corrosion from the switches.
Ensure that the switches are not stuck in the "on" position. If necessary, adjust their alignment.
Test the switches manually to confirm they activate and deactivate properly.

3. Check Interior Lighting Settings

Power on the vehicle's ignition (without starting the engine).
Navigate to the vehicle settings on the dashboard display.
Verify that the interior light settings are configured to turn off automatically after closing the doors.
Make adjustments as needed.

4. Test Wiring and Connections

Use a multimeter to check for voltage at the interior light circuit.
- Set the multimeter to the DC voltage setting.
- Probe the circuit while the doors are closed to see if it remains powered.
Inspect the wiring harness for any visible damage or loose connections.
Repair or replace any damaged wiring as necessary.

5. Reassemble and Reconnect Battery

After performing all checks and repairs, reassemble any components removed.
Reconnect the vehicle’s battery.
Ensure all connections are tight and secure.
