To access the fuse box under the hood, open the hood and look for a black plastic cover with the word "Fuses" printed on it. The cover is located near the top of the engine compartment, on the driver's side.
To access the fuse box under the dash, open the driver's side door and look for a small, black plastic panel on the side of the dash. The panel is located near the floor, just below the steering wheel.
Once you have found the fuse boxes, you can use the diagram on the inside of the cover to identify which fuse is for which circuit. If a fuse is blown, it will be blackened or melted. To replace a blown fuse, simply pull it out of the socket and insert a new fuse of the same amperage.
