* Under the hood: This is the main fuse box and usually contains larger fuses and relays. Look near the battery, often on the driver's side fender well.
* Inside the cab: This box is usually located under the dashboard, often on the driver's side, near the steering column. It typically houses smaller fuses for interior components.
To be certain, check your owner's manual. It will have a diagram showing the location of both fuse boxes and what each fuse controls. If you don't have the manual, you can often find a digital copy online through a Ford website or a third-party automotive repair manual provider.
