There isn’t a single fuse box on the 2018 Ford Explorer. The vehicle uses multiple fuse panels: an engine bay power distribution box and an interior cabin fuse box; some trims may also have a rear fuse box in the cargo area.
This article explains where to find each box, how to access them, and what they typically power, so you can safely inspect and replace fuses as needed.
Engine compartment fuse box (Power Distribution Box)
The engine compartment houses the primary fuse box, often labeled as the Power Distribution Box. It contains high-current fuses and relays for major systems.
- Location: In the engine bay, typically on the passenger side near the front or firewall. Look for a black plastic cover labeled “Power Distribution Box.”
- Access: Open the hood, lift the cover by the latch, and remove it to expose the fuse diagram.
- What it contains: Fuses and relays for engine management, charging, ABS, HVAC, and other high-current circuits.
- Diagram: The underside of the cover shows fuse/relay positions and amperage ratings.
In brief, the engine compartment fuse box is the main high-current panel you’ll consult first if you’re troubleshooting engine or electrical issues tied to major systems.
Interior fuse box (cabin)
The interior fuse box is located under the driver’s side dash. It’s accessible by removing a small trim panel and reveals a diagram on the inside of the cover.
- Location: Driver-side knee area under the dashboard; remove the panel to access the fuse box.
- Access: Pull off the trim to reveal the fuse panel and the lid diagram.
- What it contains: Fuses for interior electronics such as power windows, radio, HVAC electronics, lighting, horn, and other misc. systems.
- Diagram: The cover inside the lid lists each fuse’s function and amperage.
The cabin fuse box provides quick access to fuses for most interior and convenience features. Always ensure the vehicle is off before inspecting or replacing fuses.
Rear fuse box (optional, depending on trim)
Some 2018 Explorer configurations include a rear fuse panel in the cargo area, typically behind a side panel or under a cargo-area cover. If your model doesn’t have this box, it won’t be present.
- Location: Behind cargo-area trim on the left side, or under a dedicated panel in the rear compartment.
- Access: Remove the panel or cover to reveal fuses/relays; a diagram is usually on the panel.
- What it contains: Fuses for rear electronics, cargo area lighting, trailer wiring, and related circuits.
- Note: Availability depends on trim and options; consult the owner’s manual or the panel diagram to confirm.
Not all models have the rear fuse box, so check your vehicle’s configuration or the fuse diagram to confirm its presence.
How to identify and replace fuses
For any fuse replacement, use the amperage rating specified on the fuse or the fuse diagram. If a fuse blows repeatedly, there may be an electrical fault that requires a professional diagnosis.
When in doubt, consult the owner’s manual or the diagram on each box lid for precise fuse locations and ratings. Replacements should be of the same amperage to prevent electrical damage.
Summary
In a 2018 Ford Explorer, fuse protection is distributed across at least two panels: the engine bay Power Distribution Box and the interior cabin fuse box, with an optional rear fuse panel on some trims. Locate each box by following the diagrams on the lids and refer to the owner’s manual for exact fuse assignments and safety instructions.
