Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect Door Switches

Tools Required: None
Locate each door switch, usually positioned in the door frame where the door meets the car body.
Manually depress each switch to see if it turns the interior lights off. If they do not respond, they may need replacement.

3. Check for Obstructions

Tools Required: None
Inspect the door latches for any debris or obstructions that could prevent the switches from fully engaging when the doors are closed.
Clean any debris found to ensure proper operation.

4. Test Interior Light Switch

Tools Required: Multimeter
Remove the interior light cover to access the bulb and switch assembly.
Use a multimeter to check for continuity in the switch. If it does not show continuity when toggled, replace the switch.

5. Reconnect Battery and Configure Settings

Reconnect the negative battery terminal.
Start the vehicle and check the vehicle settings in the infotainment system to ensure interior light settings are correctly configured.
