Quick Answer
The 2024 Ford Explorer has three main fuse box locations:
- Under-hood Fuse Box: Located in the engine compartment, typically near the battery.
- Smart Junction Box (SJB) / Interior Fuse Box: Located behind the passenger side kick panel.
- Rear Cargo Area Fuse Box: Located in the rear cargo area, often behind a trim panel on the driver's side.
Keep in mind that specific fuse assignments can vary slightly between trim levels and optional equipment. Always consult the fuse diagram printed on the inside of your fuse box cover for the most accurate information for your specific vehicle.

How to Test a Fuse
Testing a fuse is a straightforward process that can help you diagnose electrical issues.
- Locate the Fuse Box: Identify the fuse box you need to check based on the affected component.
- Identify the Suspect Fuse: Consult your vehicle's owner's manual or the fuse diagram on the fuse box cover to find the fuse associated with the malfunctioning component.
- Visual Inspection: Most automotive fuses have a small wire visible through a clear housing. If this wire is broken or melted, the fuse is blown and needs to be replaced.
- Use a Fuse Tester or Multimeter: For a more definitive test, especially if the fuse isn't visibly blown, use a fuse tester or a multimeter set to continuity mode:
- Fuse Tester: Insert the fuse into the tester. If the light illuminates, the fuse is good. If not, it's blown.
- Multimeter: With the fuse removed from the fuse box, touch the multimeter probes to each metal terminal of the fuse. A reading of near zero ohms (or a beep for continuity) indicates a good fuse. An "OL" or infinite resistance reading means the fuse is blown.
- Replace Blown Fuses: Always replace a blown fuse with a new one of the exact same amperage and type. Using a fuse with a higher amperage rating can lead to serious electrical damage or fire.
Common Blown Fuses on This Vehicle
While fuses can blow for various reasons, some circuits are prone to experiencing issues due to common wear and tear, overloads, or external factors. For the 2024 Ford Explorer, commonly blown fuses might include:
- Cigar Lighter / 12V Power Outlets: These fuses often blow due to overloads from charging multiple devices or using high-power accessories that exceed the circuit
Before you pull a fuse on the 2024 Ford Explorer
- Use the label printed on the panel cover or the owner's manual for your exact build. Layouts change with options, model year and build date, so a chart for another truck can be wrong.
- Replace a blown fuse only with the same amp rating. A larger fuse can let wiring overheat.
- A fuse that blows again right away means a short or failing component downstream. Find the cause before replacing it again.
- A good fuse doesn't prove the circuit works — relays, grounds and connectors fail too.
- Disconnect the battery before working near high-current fuses or cables.
