If you have a 2015–2020 Ford F-150, knowing your fuse box can make fixing electrical problems much easier. Fuses protect important parts of your truck, from the climate control to the trailer lights.
If something stops working, it’s often a blown fuse. This guide gives you clear fuse box diagrams and locations, so you can quickly find and replace fuses to keep your F-150 working smoothly.

Tip: Some high-amperage fuses may look slightly different depending on the model year and trim. Always verify the fuse type before replacing.
Fuse Replacement Tips / Safety Precautions
- Always disconnect the negative battery terminal before removing fuses.
- Never replace a blown fuse with a higher amp rating — this can damage wiring or cause a fire.
- Use a fuse puller or needle-nose pliers for safety.
- Label replaced fuses for future reference.
Frequently Asked Questions (FAQs)
Why does the horn fuse keep blowing in an F-150?
Common causes include:
Short circuit: Damaged or exposed wiring, especially through the steering wheel, can touch metal and cause a surge that blows the fuse.
Defective horn: A faulty horn with internal issues may draw too much current, overloading the fuse.
Faulty horn switch: A stuck or defective switch can let current flow continuously, causing the fuse to blow.
Why does the cooling fan fuse blow in an F-150?
The fuse can blow for several reasons:
Short circuit: Damaged or exposed wiring touching metal can cause a surge in current.
Faulty cooling fan motor: A defective fan motor may draw too much power and overload the fuse.
Cooling system problems: If the engine overheats, the fan may run more often, putting extra strain on the fuse.
Wrong fuse: Using a fuse with lower amperage than recommended can make it blow even under normal conditions.
Why does the starter fuse blow in an F-150?
Common causes include:
Short circuit: Damaged or frayed wiring touching metal can cause a surge in current.
Faulty starter motor: A defective motor or high resistance in the circuit can overload the fuse.
Defective starter solenoid: A failing solenoid can increase current and blow the fuse.
Faulty ignition switch: A bad switch can cause spikes in current that blow the fuse.
Battery or alternator issues: Low voltage or irregular charging can overload the electrical system and affect the starter fuse.
