- Faulty door switch: If the door switch is faulty, it may not properly register that the door is closed, causing the interior lights to remain on.
- Faulty light switch: If the light switch is faulty, it may not properly turn off the lights when you leave the vehicle.
- Short circuit: A short circuit in the electrical system can also cause the interior lights to remain on. This can be caused by damaged wires or loose connections.
- Aftermarket accessories: If the interior lights come on after installing any aftermarket accessories like a stereo, dashcam, etc, the accessories could be causing the issue. Check if the accessories are wired into the vehicle's electrical system correctly, or if there's a power draw when the vehicle is off.
- Faulty BCM (Body Control Module): The BCM controls various electrical functions in the car, including the interior lighting. If the BCM malfunctions, it can cause the lights to stay on even when the car is off.
*It's important to have these issues diagnosed and repaired to prevent battery drain and potential electrical problems in the vehicle.*
