You drive one of the most reliable trucks ever: the 1997–2003 Ford F-150. It’s tough, but even a dependable truck can have small electrical issues—like a dead radio, a silent horn, or flickering lights—all caused by a tiny blown fuse.
Instead of guessing, wasting time, or going to a mechanic, you need a clear guide.
This guide gives you a simple, complete look at the 1997-2003 Ford F-150 fuse box diagram. You’ll see where the power goes and what each fuse controls, so you can quickly find the problem, replace the blown fuse, and get your F-150 running like new.
Note: In the event that you need to disconnect and reconnect the battery, it's important to note that certain features may require resetting. This step is necessary to restore their functionality.

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 radio fuse blow in the F-150?
The radio fuse can blow due to: Short circuit: Damaged or frayed wires, or the radio itself, can cause excess current. Extra devices: Adding amplifiers or accessories on the same circuit can overload the fuse. Wrong fuse: Using a fuse with lower amperage than recommended. Radio defect: A faulty radio may draw too much power. Electrical issues: Problems like a bad alternator can cause voltage spikes that blow the fuse.
Why does the cigarette lighter (power socket) fuse blow in the F-150?
The fuse can blow due to: Overload: Devices that draw too much power (e.g., chargers, compressors, inverters). Short circuit: Damaged wires or contact with metal can cause excess current. Faulty adapters: Low-quality or defective adapters may overload the circuit. Wrong fuse: Using a fuse with lower amperage than recommended.
Why does the headlight fuse blow in the F-150?
The fuse can blow due to: Short circuit: Damaged or frayed wires touching metal. Defective bulb: A faulty or burned-out bulb can overload the fuse. Faulty switch: A bad headlight switch can cause current spikes. Extra components: Added lights or modifications can overload the circuit.
