Understanding Your 2017 Ford Explorer’s Electrical System
Your 2017 Ford Explorer is packed with electrical components, from the engine control unit to your power windows and infotainment system. Each of these components relies on a steady flow of electricity.
Fuses are tiny but critical safeguards. They act as circuit breakers, designed to melt and break a circuit if too much current flows through it.
This prevents damage to more expensive components like wiring harnesses, modules, or the device itself. Think of them as the weakest link, intentionally designed to fail first.
When a fuse blows, it means there’s an electrical fault somewhere in that circuit. This could be a short circuit, an overloaded component, or even just a faulty accessory.
Learning to identify a blown fuse and replace it is a fundamental skill for any Explorer owner or DIY mechanic.
The Role of Fuses and Relays
Fuses protect individual circuits from overcurrent. Each fuse has a specific amperage rating, indicating the maximum current it can safely handle.
Relays, on the other hand, are electrical switches. They use a small current to control a much larger current, often for high-power components like headlights, fuel pumps, or the starter motor.
While this guide focuses on fuses, it’s good to know that relays also reside in your fuse boxes and can sometimes be the source of an electrical problem.
Locating the 2017 Ford Explorer Fuse Box Diagram
Your 2017 Ford Explorer has multiple fuse boxes, each dedicated to protecting different sets of electrical circuits. Knowing where to find them is the first crucial step in any electrical troubleshooting.
The 2017 Ford Explorer fuse box diagram for each location is usually printed on the inside of the cover or detailed in your owner’s manual.
Always consult your owner’s manual for the most accurate and specific diagrams for your vehicle’s trim level.
Passenger Compartment Fuse Panel (Interior)
This fuse box is typically located inside the cabin, usually on the passenger side. It’s often behind a trim panel or kick panel.
For the 2017 Explorer, you’ll generally find it tucked away in the footwell area, sometimes requiring you to remove a small access door or cover.
This panel controls interior accessories like the radio, power windows, dashboard lights, heated seats, and charging ports.
To access it, you might need a small flat-head screwdriver or a trim removal tool to gently pry open the cover.
Battery Junction Box (Engine Compartment)
The main fuse box for the engine and other high-current systems is located under the hood. It’s often referred to as the Battery Junction Box (BJB) or Power Distribution Box.
You’ll typically find it on the passenger side of the engine bay, near the battery. It’s a black plastic box with a secure lid.
This box houses fuses and relays for critical components like the engine control module (ECM), anti-lock braking system (ABS), cooling fan, headlights, and other heavy-duty electrical loads.
Always ensure the vehicle is off and the key is removed from the ignition before opening this box.
Deciphering the Fuse Box Layout
Once you’ve located a fuse box, the next step is to understand its layout. Each fuse box cover usually has a label or diagram on its underside.
This diagram is your map, showing the location and function of each fuse and relay. It also indicates the amperage rating for each fuse.
Familiarize yourself with the symbols and abbreviations used. Often, a small legend will be provided.
Reading the Diagram and Amperage Ratings
The diagram will typically show a grid representing the physical layout of the fuses. Each position will have a number or a symbol.
Next to this, you’ll find an abbreviation or a full description of the circuit it protects (e.g., “RADIO,” “PWR WIN,” “HEADLP”).
Crucially, the diagram will also specify the correct amperage for each fuse. Fuses are color-coded by their amperage rating:
- Tan: 5 Amp
- Brown: 7.5 Amp
- Red: 10 Amp
- Blue: 15 Amp
- Yellow: 20 Amp
- Green: 30 Amp
- Maxi Fuses (larger): Often higher amps like 40, 50, or 60 Amp, and may have different colors.
Always replace a blown fuse with one of the exact same amperage rating. Using a higher-rated fuse can cause severe damage or even a fire.
Common Electrical Issues and Fuse Troubleshooting
When an electrical component stops working, a blown fuse is often the simplest and most common culprit. Here’s how to approach troubleshooting.
Before you begin, gather your tools: a fuse puller (usually found in one of the fuse boxes), a flashlight, and potentially a multimeter for more advanced checks.
Always ensure your vehicle is turned off, and the ignition key is removed, especially when working with fuses in the engine bay.
Step-by-Step Fuse Inspection
- Identify the malfunctioning component: Is it the radio, a power outlet, or the dome light?
- Consult the 2017 Ford Explorer fuse box diagram: Locate the fuse responsible for that specific component in the appropriate fuse box (interior or engine compartment).
- Access the fuse box: Remove the cover carefully.
- Visually inspect the suspected fuse: Use your fuse puller to carefully remove the fuse. Hold it up to a light. A good fuse will have a continuous wire filament inside. A blown fuse will have a broken or burnt filament.
- Test with a multimeter (optional but recommended): If a visual inspection isn’t clear, set your multimeter to continuity mode. Touch the probes to the two metal test points on top of the fuse. A good fuse will show continuity (a beep or a low resistance reading). A blown fuse will show no continuity.
- Replace the fuse: If the fuse is blown, replace it with a new fuse of the exact same amperage rating and type. Never use a fuse with a higher rating.
If the new fuse blows immediately, there’s a deeper electrical issue, likely a short circuit, that needs professional diagnosis.
Troubleshooting Specific Components
Here are some common issues and their typical fuse locations:
- Radio/Infotainment System: Check fuses labeled “RADIO,” “AUDIO,” or “SYNC” in the passenger compartment fuse panel.
- Power Windows/Sunroof: Look for fuses labeled “PWR WIN” or “SUNROOF” in the passenger compartment panel. Each window might have its own fuse.
- Headlights/Tail Lights: These are usually protected by fuses in the Battery Junction Box under the hood, often labeled “HEADLP LH,” “HEADLP RH,” “TAILLP,” or similar. Relays are also common culprits here.
- 12V Power Outlets/USB Chargers: Check fuses labeled “CIGAR,” “ACC,” “PWR OUTLET,” or “USB” in the passenger compartment fuse panel. These are frequently blown by overloaded devices.
- Trailer Wiring/Tow Package: Fuses for trailer lights, brake controller, and auxiliary power are usually located in the Battery Junction Box. These can blow if there’s a short in the trailer’s wiring.
Safety First: Working with Automotive Fuses
Working with any electrical system, even low-voltage automotive systems, requires caution. Always prioritize safety to prevent injury or damage to your vehicle.
These simple steps will help ensure a safe troubleshooting experience.
Essential Safety Precautions
- Turn Off the Vehicle: Always turn off the ignition and remove the key before opening any fuse box, especially the one under the hood. This prevents accidental shorts or activating circuits.
- Disconnect the Battery (for major work): If you’re undertaking more extensive electrical work beyond just replacing a fuse, disconnect the negative terminal of your battery. This eliminates all power to the vehicle’s electrical system.
- Use the Correct Tools: Always use a plastic fuse puller. Avoid using metal pliers or screwdrivers, which could accidentally short circuits.
- Never Use a Higher Amperage Fuse: This is critical. A higher-rated fuse allows more current to flow than the circuit is designed for, leading to overheating, melted wires, and potential fires.
- Never Use Aluminum Foil or Wire: This is an extremely dangerous practice. It bypasses the safety mechanism entirely and can cause severe damage or fire.
- Wear Eye Protection: Sparks are rare with fuses, but it’s always wise to protect your eyes when working in the engine bay.
- Work in a Well-Lit Area: A good flashlight is essential for clearly seeing the tiny fuse filaments and reading the diagram.
If you’re unsure at any point, or if fuses keep blowing, it’s always best to consult a certified automotive technician. They have the specialized tools and knowledge to diagnose complex electrical faults.
Advanced Tips for DIYers and Off-Roaders
For those who venture off the beaten path or love to customize their ride, understanding your Explorer’s electrical system goes beyond basic fuse replacement.
Adding accessories, managing power draw, and preparing for remote scenarios require a bit more foresight.
Adding Aftermarket Accessories
Many DIYers want to add auxiliary lights, a winch, a fridge, or additional charging ports. When doing so, it’s vital to do it correctly.
Always wire new accessories to a fused circuit. Ideally, use an add-a-circuit adapter to tap into an existing circuit that isn’t critical and has some spare capacity, or install a dedicated auxiliary fuse block.
Never overload an existing circuit. Calculate the amperage draw of your new accessory and ensure the chosen circuit or new fuse block can handle it.
For high-power accessories like winches, always run a dedicated heavy-gauge wire directly from the battery, protected by a large inline fuse or circuit breaker close to the battery.
Off-Road and Remote Scenarios
When you’re far from civilization, a simple electrical problem can become a major headache. Always carry a spare fuse kit with a variety of common amperage ratings.
A multimeter is an invaluable tool for diagnosing issues beyond just blown fuses, helping you check voltage and continuity in remote locations.
Before any major trip, especially off-roading, inspect your wiring harnesses for chafing or damage that could lead to shorts. Secure loose wires to prevent them from getting snagged or abraded.
Consider installing a dual-battery setup for heavy accessory use. This isolates your starting battery from the deep-cycle battery powering your accessories, preventing you from draining your main battery and getting stranded.
If you encounter a persistent electrical issue in a remote area and cannot diagnose it, conserve battery power. Use a satellite communicator or cell phone (if available) to call for assistance. Park rangers or experienced off-roaders can often provide guidance or tools.
