Fuel warning light is not working?

If the fuel warning light is not functioning, it may indicate a blown fuse, a faulty bulb, or an issue with the fuel level sensor in the tank. It's important to check the vehicle's fuse box for any blown fuses related to the instrument cluster. If the fuse is intact, you may need to inspect the bulb or the sensor itself, which may require professional assistance. Regularly monitoring the fuel gauge and refueling before it gets too low can help prevent running out of fuel in the meantime.
