2025 Ford Explorer Fuse Box Diagram & Amperage

Quick Answer

The 2025 Ford Explorer features multiple fuse box locations to protect its complex electrical systems. You'll find fuse boxes located:

• Under the Hood: In the engine compartment, typically near the battery.
• Passenger Compartment (Dash Kick-Panel): Located on the passenger side, behind a removable panel near the footwell.
• Rear Cargo Area: Often on the driver's side, behind a trim panel.

Always consult your owner's manual and the fuse box lid for the most accurate and up-to-date diagram for your specific vehicle's trim level.

Under-Hood Fuse Box (Battery Junction Box)

This fuse box, often called the Battery Junction Box (BJB), is located in the engine compartment, usually on the driver's side near the battery. It houses fuses and relays for critical engine functions, powertrain control, ABS, and other high-current circuits. Relays for the PCM, fuel pump, ignition, and starter are often found here.

Passenger Compartment Fuse Box (Smart Junction Box)

This fuse box, often referred to as the Smart Junction Box (SJB), is typically located on the passenger side of the cabin, behind a kick panel near the footwell. It manages power distribution for many interior electrical components, including the radio, infotainment, power windows, wipers, and various cabin accessories.

Rear Cargo Area Fuse Box

Some 2025 Ford Explorer models may feature a third fuse box located in the rear cargo area, often behind a trim panel on the driver's side. This fuse box typically controls power for rear accessories, the tailgate, and any optional rear passenger features.

Note: Fuse box configurations can vary based on trim level, options, and regional specifications. Always refer to the fuse legend printed on the inside of your fuse box cover or your vehicle's owner's manual for the exact layout and amperage ratings for your 2025 Ford Explorer.

How to Test a Fuse

If an electrical component in your Ford Explorer stops working, a blown fuse is often the culprit. Here's how you can test a fuse:

1. Locate the Fuse Box: Identify the correct fuse box (under-hood, dash, or rear cargo) using the information above.
2. Identify the Suspect Fuse: Consult the fuse diagram (on the lid or in the manual) to find the fuse corresponding to the non-working component.
3. Visual Inspection: Most fuses have a small wire or filament visible through a clear plastic body. If this wire is broken or charred, the fuse is blown and needs replacement.
4. Use a Fuse Tester (Recommended): For a more reliable test, use a fuse tester or a multimeter. With the ignition off, touch the tester leads to the two small metal test points on top of the fuse. If the tester lights up (or shows continuity on a multimeter), the fuse is good. If not, it's blown.
5. Remove and Replace: Carefully remove a suspected blown fuse using a fuse puller (usually found in the fuse box or tool kit), or small needle-nose pliers. Always replace a blown fuse with a new fuse of the exact same amperage rating and type. Using a fuse with a higher rating can cause serious electrical damage or fire.

Common Blown Fuses on This Vehicle

While any fuse can blow, some circuits are more prone to issues due to their constant use or the components they protect:

• Cigar Lighter/12V Outlets: These fuses often blow due to short circuits from faulty charging accessories, over-current draws from high-power devices, or foreign objects lodged in the outlet. If your phone charger or air compressor stops working, check these fuses first.
• Radio/Infotainment: Issues with aftermarket head units, faulty wiring, or even minor electrical glitches can sometimes lead to this fuse blowing. If your audio system suddenly goes dead, this is a good place to start troubleshooting.
• Blower Motor: The blower motor fuse can blow if the motor itself is failing, or if there's a blockage preventing the fan from spinning freely, causing an over-current draw. If you have no cabin air movement, check this fuse and then the blower motor itself.
• Headlights/Tail Lights: While less common on modern vehicles, a short in the wiring or a faulty bulb (especially with aftermarket HID/LED conversions) can sometimes cause a headlight or taillight fuse to blow. If one or both lights are out, check the respective fuses.

Always check the easiest-to-access fuses first related to the affected component. If a new fuse blows immediately, there's likely a short circuit or a component drawing too much current, and professional diagnosis is recommended.
