Why is the interior lights on your 2006 transit van not working?

The interior lights in your 2006 Transit van may not be working due to a blown fuse, which is a common issue that can disrupt electrical systems. Additionally, the light switch or door sensors might be malfunctioning, preventing the lights from activating when the doors are opened. It's also worth checking the bulbs themselves to see if they need replacing. If these components are functioning correctly, it could indicate a deeper electrical issue that may require professional diagnosis.
