* Under the hood: This is the most common location for power distribution fuses and relays. The fuse box is usually located near the battery. The cover should have a diagram showing which fuse controls what.
* Inside the cab: There's usually a smaller fuse panel or fuse block inside the cab, often located near the steering column, under the dashboard, or in the center console. This panel usually handles smaller circuits for interior features.
To be absolutely certain:
* Consult your owner's manual: This is the best source for the precise location and a diagram of your vehicle's fuse boxes. The manual will clearly show which fuse controls what circuit.
* Look for labels: The fuse boxes themselves often have labels indicating what each fuse protects.
Without your owner's manual, I cannot give you a more specific location. Remember to always turn off the truck before checking fuses.
