If you own a Ford F-150 from 2009 to 2014, having the correct fuse box diagram is essential for keeping your truck’s electrical system running smoothly. Fuses protect critical components—like the headlights, radio, power windows, and fuel pump—from electrical shorts or surges. Without the right diagram, locating a blown fuse can be a frustrating task.
This article provides complete fuse box layouts and diagrams for every F-150 model year from 2009 through 2014. Whether you’re troubleshooting an electrical issue or replacing a fuse, you’ll find clear, easy-to-follow diagrams to help you quickly identify the correct fuse and get your truck back in working order.

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 brake light fuse keep blowing in an F-150?
The fuse usually blows because of one of these issues:
Short circuit: Damaged or exposed wiring touching metal parts can cause a power surge.
Bad brake bulb: A faulty or burned-out bulb can draw too much power or short out.
Faulty brake light switch: A worn or defective switch can cause spikes in current.
Wrong fuse: Using a fuse with lower amperage than recommended will make it blow more easily.
Why does the headlight fuse keep blowing in an F-150?
Common causes include:
Short circuit: Damaged or exposed wiring touching metal parts can cause a surge in current.
Bad headlight bulb: A burned-out or faulty bulb may short out or draw too much power.
Faulty headlight switch: A defective switch can cause current spikes that blow the fuse.
Aftermarket lighting: Adding LED lights or extra headlights can overload the circuit if it’s not designed for the extra power.
Why does the fog light fuse keep blowing in an F-150?
The fuse may blow due to:
Short circuit: Damaged or exposed wiring touching metal can cause a surge in current.
Bad fog light bulb: A faulty bulb can draw too much power and overload the fuse.
Faulty fog light switch: A defective switch can cause current spikes or malfunctions.
Aftermarket lighting: Adding LED lights or other modifications can overload the circuit if it’s not properly upgraded.
Why does the cooling fan fuse blow in an F-150?
The fuse can blow because of:
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 issues: Engine overheating can make the fan run more often, stressing the fuse.
Wrong fuse: Using a fuse with lower amperage than recommended increases the chance of it blowing.
