How does the car cigarette lighter fuse work?

If your cars cigarette lighter is not working, it could be due to a blown fuse. The car cigarette lighter fuse is designed to protect the electrical system from power surges and prevent damage to the cars components. This fuse acts as a safety measure and is located in the fuse box of your car. When the cigarette lighter is overloaded or short-circuited, the fuse will blow, cutting off the power supply to the lighter socket.

Check the fuse box in your car to locate the fuse for the cigarette lighter. Use the cars manual or the diagram on the fuse box cover to identify the correct fuse. Once you locate the fuse, check if it is blown by inspecting the wire inside the fuse. If the wire is broken or melted, replace the fuse with a new one of the same rating.

If the fuse keeps blowing repeatedly, there may be an underlying issue causing the excessive power draw. In this case, it is recommended to consult a professional mechanic or an auto electrician to diagnose and repair the problem.

It is important to note that the cigarette lighter socket is designed to power accessories with low power requirements, such as phone chargers or portable electronic devices. Avoid using it for high-power devices like power inverters or heated appliances, as they can cause the fuse to blow and potentially damage the electrical system of your car.
