Access to the power distribution units in this mid-size SUV requires attention to two primary locations: beneath the front hood near the battery module and inside the passenger compartment along the driver-side lower panel. Remove the protective covers carefully, as each section contains relays and current protection elements assigned to lighting, infotainment, climate control, and driver assistance systems. A printed scheme is typically fixed to the inner side of the крышка, allowing quick identification of each slot.
For accurate diagnostics, match the amperage rating stamped on each element with the required circuit load. For example, high-demand components such as cooling fans or heated seats use higher-rated inserts, while control modules rely on lower values. Misplacement or substitution with incorrect ratings may lead to wiring damage or malfunction of electronic units.
Pay attention to numbering orientation: rows are arranged sequentially, but mirrored positioning between the engine compartment and interior panel can cause confusion. Use a flashlight and label reference when checking continuity or replacing a burnt component. Keeping spare inserts of multiple ratings inside the vehicle ensures quick restoration of critical systems during unexpected failures.

Check the interior power distribution panel under the dashboard on the driver’s side first; it handles critical circuits such as infotainment, climate control, and interior lighting, while the engine compartment unit near the battery manages high-load systems like cooling fans, ABS, and ignition modules. Each slot is labeled with amperage ratings (typically ranging from 5A to 40A), and mismatched ratings can damage wiring or cause intermittent faults. For quick identification, refer to the cover legend or the service manual where each circuit is mapped with its corresponding component. Pay attention to relays in the engine bay assembly, as they control switching operations for fuel pumps and starter systems, and failures there can mimic more complex mechanical issues.
If a system stops working, inspect the relevant circuit link visually for a broken filament or discoloration, then confirm continuity with a multimeter rather than relying solely on appearance. Replace only with identical amperage ratings and avoid temporary fixes like bypassing, which may lead to overheating or wiring damage. Recurrent failures in the same slot often indicate a short circuit or a failing component drawing excessive current, such as a worn blower motor or malfunctioning control module; in such cases, trace the circuit path using wiring schematics and isolate the load by disconnecting connected devices one at a time.
Exact Locations of Fuse Boxes in the 2023 Ford Explorer and How to Access Them Step by Step
Open the hood and go straight to the engine compartment unit placed on the driver’s side near the battery terminal. Release the hood latch from inside the cabin, lift the hood, and secure it with the prop rod. Locate the rectangular plastic housing with locking tabs. Press the side clips inward and lift the cover upward; no tools are required. Inside, you will see a molded layout showing circuit assignments and a plastic puller for removing elements safely.
The interior panel is positioned beneath the dashboard on the driver’s side, slightly left of the steering column. To reach it, kneel near the driver’s seat and look under the lower trim panel. A small cover is integrated into the trim; pull it gently from the notch at the bottom edge. The compartment behind it contains low-amperage circuits related to cabin electronics such as infotainment, lighting, and auxiliary ports.
For rear electrical distribution, check the cargo area on the passenger side. Lift the rear hatch, fold back the side trim panel near the tail light cluster, and you will find a concealed compartment. The cover is secured with light clips; pull it outward evenly to avoid breaking them. This section typically handles rear accessories, power liftgate, and trailer-related circuits.
Follow this access sequence for any of the three locations:
- Turn off the ignition and remove the key or disable push-button start.
- Disconnect the negative battery terminal when working in the engine compartment.
- Open the appropriate panel using built-in clips–avoid metal tools.
- Use the provided puller to remove a component; match amperage rating exactly.
- Reinstall the cover firmly, ensuring all clips engage to prevent moisture ingress.
