* Under the hood: This fuse box typically houses higher amperage fuses protecting major electrical components. Look for a black plastic box near the battery.
* Inside the car: This fuse box, often called the "passenger compartment fuse panel," is usually located on the driver's side, often under the dashboard near the steering column or in the glove box. Check your owner's manual for the precise location. It will have smaller fuses protecting interior lights, power windows, etc.
