Check the panel cover first: it usually contains a compact layout reference showing exact slot positions, amperage ratings, and circuit assignments, which helps you locate the correct element within seconds without trial and error.
The electrical center in this vehicle is split into two main units: one under the hood near the battery and another inside the cabin beneath the dashboard on the driver’s side. The engine compartment module handles high-load systems such as cooling fans, ABS, and ignition components, while the interior module distributes power to lighting, infotainment, and accessory circuits.
Each slot is marked with a number and a specific amperage value (for example, 10A, 15A, 20A). Matching these ratings is mandatory–installing a higher value can damage wiring. For instance, the circuit responsible for the infotainment system typically uses a low-amperage element, while power seats or climate control rely on higher-rated positions located in the under-hood unit.
Use a multimeter or a test light to verify continuity before replacing any component. If a slot repeatedly fails after replacement, inspect the connected circuit for short conditions rather than swapping parts blindly. The panel mapping also indicates spare positions and relay placements, which are often overlooked but critical for diagnosing starting or lighting issues.
Keep a printed or saved reference of the electrical slot arrangement specific to this vehicle configuration, as variations exist depending on trim level and installed options such as towing packages or advanced driver assistance systems.

Check the primary power distribution unit under the hood near the battery; this is the first place to inspect when electrical components fail. A secondary panel is installed inside the cabin, typically beneath the dashboard on the driver’s side. Use the lid marking or service manual to identify circuits tied to lighting, infotainment, or climate systems.
The engine compartment module contains high-amperage protection elements for systems like ABS, cooling fans, and ignition. Inside the cabin, smaller-rated inserts control accessories such as power windows, radio, and interior lighting. Each slot is labeled with a number and function, allowing quick identification without guesswork. Misplacing even a single insert can lead to partial system failure.
When diagnosing a malfunction, remove the suspected insert using a puller tool and inspect the metal strip. A broken or burned strip indicates failure. Replace only with identical amperage; installing a higher-rated part risks wiring damage. Color coding helps avoid mistakes: for example, yellow usually indicates 20A, blue 15A, and red 10A.
Intermittent faults often trace back to loose seating rather than a blown component. Press each insert firmly into its slot and check for corrosion or moisture, especially in the under-hood unit. Water ingress can disrupt contact points and cause random shutdowns of systems like wipers or headlights. Cleaning terminals with electrical contact cleaner can restore proper function.
If multiple systems stop working simultaneously, inspect main relays and large protection elements in the engine bay module. These control power distribution to entire sections of the vehicle. A failed relay may mimic several separate faults, so swapping with a known working relay of the same type can quickly confirm the issue.
Exact fuse box locations in the 2017 Ford Explorer and how to access each compartment safely
Open the hood and go straight to the front-left area near the battery to find the primary power distribution unit; release the plastic latches on both sides and lift the cover vertically without twisting to avoid cracking the clips. A second compartment sits inside the cabin, hidden behind the lower dashboard on the driver’s side–remove the trim panel by pulling it evenly from the edges rather than prying at one corner.
Under-hood power module access
This unit is mounted close to the battery for direct current routing and contains high-amperage links. Use these steps to access it without damage:
- Switch off ignition and remove the key to cut electrical flow.
- Wait at least 2 minutes to allow modules to power down.
- Press both side tabs simultaneously and lift the lid straight up.
- Check the underside of the cover for the circuit layout reference.
- Reinstall by aligning grooves and pressing until both clips click firmly.
Interior panel behind dashboard
The cabin-mounted unit is positioned behind a removable panel beneath the steering column and slightly to the left; clearance is tight, so move the seat backward fully before working. Follow a controlled sequence:
- Grip the panel along its outer edge and pull gently to release retaining clips.
- Do not use metal tools, as they can mark surfaces or break fasteners.
- Locate the small puller tool stored inside the compartment for extracting mini blade elements.
- After inspection, align the panel tabs with slots and press evenly until flush.
Work only with dry hands and avoid contact with exposed terminals; if resistance is felt while removing or installing components, stop and realign rather than forcing movement.
