2025 Ford Ranger Fuse Box Diagram & Amperage

Quick Answer

The 2025 Ford Ranger features multiple fuse box locations to protect its electrical systems. You'll find fuse boxes under the hood, inside the cabin behind the passenger kick panel, and in the cargo area.

Under-Hood Fuse Box (Power Distribution Box)

The main power distribution box is located in the engine bay, typically near the battery. This box houses fuses and relays for critical engine functions, lights, and other high-current components. Always consult the diagram on the fuse box lid for the most accurate information as configurations can vary slightly by trim level.

Relays: The under-hood fuse box also contains several relays for components like the starter, fuel pump, and cooling fan. Refer to the fuse box lid diagram for specific relay locations.

Passenger Kick Panel Fuse Box

This fuse box is located inside the cabin, typically behind the passenger side kick panel. It protects various interior electrical components, accessories, and some lighting circuits.

Relays: This fuse box may contain relays for accessories like power windows or door locks. Consult the fuse box diagram on the cover.

Cargo Area Fuse Box

For models equipped with a cargo area fuse box (often found in the bed or rear quarter panel for certain configurations or accessories), it typically manages power for rear accessories, trailer wiring, or additional power outlets.

Relays: Specific relays for trailer functions or cargo area accessories may be present here. Always check the fuse box lid.

How to Test a Fuse

Testing a fuse is a straightforward process:

1. Locate the Fuse Box: Identify the correct fuse box for the circuit you're troubleshooting.
2. Identify the Suspect Fuse: Refer to the fuse box diagram to find the fuse associated with the problematic component.
3. Visual Inspection: Many fuses have a clear plastic body. Look for a broken wire or a dark, burnt appearance inside the fuse. A good fuse will have a continuous strip of wire.
4. Use a Fuse Tester or Multimeter: For a more accurate test, use a automotive fuse tester or a multimeter set to continuity mode.
   • With a Tester: Touch the probes of the tester to the two test points on top of the fuse (most modern fuses have these). If the light on the tester illuminates, the fuse is good. If not, it's blown.
   • With a Multimeter: Remove the fuse from its slot. Place the multimeter probes on each metal blade of the fuse. If the multimeter beeps or shows a reading close to zero ohms, the fuse is good. If it shows "OL" (open loop) or no continuity, the fuse is blown.
5. Replace if Necessary: If the fuse is blown, replace it with a new fuse of the exact same amperage rating and color. Never use a fuse with a higher amperage rating, as this can lead to serious electrical damage or fire.

Common Blown Fuses on This Vehicle

While any fuse can blow, some are more common than others due to their circuit's demands or common user actions:

• Cigar/12V Power Outlets: These often blow due to overloading from charging multiple devices or using high-power accessories. If your phone charger or other accessories aren't working, check the fuse for the 12V outlets (typically F2 in the passenger kick panel fuse box for the interior outlet, and F2 in the cargo area for a rear outlet).
• Headlights/Taillights: While less common with modern LED lighting, a short in a wiring harness or an issue with the bulb itself (if applicable for certain trims) can cause a headlight or taillight fuse to blow. If one of your headlights or taillights isn't working, check the corresponding fuse in the under-hood fuse box (F5-F8 for headlights, F6 in the cabin for taillights).
• Blower Motor: The blower motor fuse (F9 under the hood) can sometimes blow if the motor is struggling due to debris, a failing resistor, or prolonged use on high settings. If your HVAC fan isn't working at all, this is a prime suspect.
• Radio/Infotainment: Issues with aftermarket accessories, wiring shorts, or internal unit faults can cause the radio/infotainment fuse (F1 in the passenger kick panel) to blow, leading to a blank screen or no audio.

Always check the fuse first when an electrical component stops working. If the fuse blows again immediately after replacement, it indicates a deeper electrical issue that needs professional diagnosis.
