When an electrically-powered component of your vehicle such as the interior dome light or the radio stops working, you may be able to fix the issue on your own. Electrical power is distributed to these and other devices through circuits. The electricity travels from the source along the circuit to each device, and different items require different levels of power to operate.

If too much electricity tries to make its way to a particular device, it could damage the equipment, which is why there are fuses attached to every circuit. They are designed to break when there is a problem with the electrical current as a means of protecting the devices on the circuit.

There are often two different fuse panels in a car, one in the engine bay and the other underneath the dash. The latter is connected to electrical devices inside the passenger cab, and the owner's manual will contain a diagram to help you figure which fuse is connected to which device. You can easily remove a fuse with your hands or a pair of tweezers. Inside the plastic casing is a metal filament. If it is broken, you will need to replace the fuse.

Even if you replace the fuse, you should still have the car checked out by a professional mechanic. A fuse blows when there is too much electrical current on a particular circuit. This could be caused by faulty wiring or an issue with one of the parts being powered by electricity.
