Under the hood: Fusebox and cover
There is always at least one fusebox on a car, but there are often more than one, in multiple locations. The most common location for the fusebox, or fuseblock inside the passenger's compartment, is under the dashboard, roughly at the driver's left knee. Other locations can include inside the glove compartment or under the dashboard in another location. The boxes are labeled "Fuses" on the plastic cover, which has a handle molded into it. The other fuseboxes are under the hood of the car, and are about 4 inches wide and 8 inches long. They are usually placed in accessible locations and covered tightly to protect them from moisture. They may be marked "Relay" or "Power Distribution Center."
Cover, diagram, tool and spare fuses
Fuseboxes are always covered to prevent moisture damage and inadvertent dislodging of the fuses. There is always a diagram that illustrates where each fuse is located, what its amperage is and what it controls. This is usually found on the inside of the cover. (This information is also available in the owner's manual.) Many fuseboxes have a dedicated slot to hold a tool with which to remove fuses, because many mini-fuses are difficult to remove with your fingers. Spare fuses are also sometimes kept in the fusebox. Flashers that cause the hazard lights and turn signals to light intermittently may be found here as well. Fuseboxes located under the hood may also contain relays that help operate integral parts of the cooling and fuel-supply systems.
