2020 Ford Expedition Fuse Box Diagram – Locate, Identify, And Replace
This guide provides a detailed breakdown of the fuse locations and assignments for the 2020 Ford Expedition. Whether you are troubleshooting a dead power outlet or a flickering headlight, knowing where to find your fuses is essential for a quick fix.
We have all been there—miles from home on a family road trip when the USB ports suddenly stop charging or the windshield wipers quit during a downpour. It is a frustrating moment that can make a simple drive feel like a major mechanical failure.
Finding a 2020 ford expedition fuse box diagram is the first step toward regaining control over your vehicle’s electrical systems. Most electrical “breakdowns” are actually just a small piece of wire inside a plastic housing that did its job by melting to protect your expensive electronics.
In this guide, I will show you exactly where Ford hid these panels and how to read the diagrams like a professional technician. You will learn how to identify blown fuses, use the right tools, and get back on the road without a costly trip to the dealership.
Where to Find the Fuse Boxes in Your 2020 Ford Expedition
The 2020 Ford Expedition uses a decentralized electrical system, meaning there is more than one place where fuses live. To troubleshoot effectively, you need to know which box handles which specific functions of the vehicle.
There are two primary locations you need to be aware of: the Passenger Compartment Fuse Panel and the Power Distribution Box located under the hood. Each serves a distinct purpose in protecting your SUV’s complex wiring.
The Passenger Compartment Fuse Panel
This panel is located inside the cabin, tucked away on the right-hand side of the passenger footwell. You will need to remove a plastic trim cover to access it, which can be done by gently pulling the panel toward you.
This interior box generally handles “low-current” electronics. Think of things like your infotainment system, interior lighting, power windows, and the various sensors that make the cabin comfortable.
The Under-Hood Power Distribution Box
For high-current applications, Ford placed a larger fuse box in the engine bay. It is located near the battery on the driver’s side of the vehicle and is protected by a heavy-duty plastic lid.
This box manages the “heavy lifters” of your Expedition. It contains fuses and relays for the fuel pump, cooling fans, anti-lock brake system (ABS), and the starter motor.
How to Read Your 2020 ford expedition fuse box diagram
Looking at a fuse box for the first time can feel like staring at a bowl of colorful cereal. However, every slot is numbered, and each color represents a specific amperage rating that must be respected.
The 2020 ford expedition fuse box diagram acts as your map, correlating a number on the plastic housing to a specific circuit in the car. For example, a 15A blue fuse might be assigned to your cigar lighter, while a 30A green fuse handles the power seats.
It is vital to never replace a fuse with one of a higher rating. If a circuit is designed for 10 amps and you put in a 20-amp fuse, you risk melting the wiring harness or even starting an electrical fire before the fuse can blow.
Understanding Modern Fuse Types
Modern Fords use several different types of fuses that look different from the classic “blade” fuses of the 90s. In your 2020 Expedition, you will likely encounter Micro2, Micro3, and MCase fuses.
Micro2 fuses are very small and have two prongs, while Micro3 fuses have three prongs and handle two circuits at once. MCase fuses are boxier and usually handle higher currents, often found in the engine bay distribution box.
Common Fuse Assignments in the Passenger Compartment
If your interior electronics are acting up, the passenger kick panel is the first place to look. Below are some of the most common fuses owners need to check during a DIY repair.
- Fuse 1 (10A): Demand lighting and glove box lamp.
- Fuse 10 (15A): Power windows and adjustable pedals.
- Fuse 15 (20A): Gateway module (essential for OBD-II diagnostics).
- Fuse 19 (7.5A): Moonroof and auto-dimming mirror.
- Fuse 26 (30A): Driver side power window motor.
When pulling these fuses, always use a dedicated fuse puller tool. These are often located inside the engine bay fuse box lid, but having a pair of needle-nose pliers in your glovebox is a smart move for any off-roader.
Navigating the Under-Hood Power Distribution Box
The engine bay fuse box is built to withstand heat and vibration. Because it handles high-voltage components, you should always ensure the engine is completely off before opening this cover.
Referencing the 2020 ford expedition fuse box diagram for the engine bay is crucial for trailer towing and performance issues. If your trailer lights aren’t working, the problem is almost always a blown fuse in this specific box.
Critical Engine Bay Fuses
- Fuse 11 (30A): Trailer tow park lamps.
- Fuse 15 (25A): Wiper motor (essential for safety in rain).
- Fuse 44 (50A): Antilock brake system pump.
- Fuse 82 (20A): Fuel pump power.
If your Expedition cranks but won’t start, checking Fuse 82 could save you a $200 towing fee. A simple visual inspection of the metal bridge inside the fuse will tell you if it has failed.
Essential Tools for DIY Fuse Troubleshooting
While you can sometimes see a blown fuse with your eyes, a “ghost break” can occur where the fuse looks fine but is actually dead. To work like a pro, you need a few basic tools in your kit.
A digital multimeter is the gold standard for testing. Set it to the “continuity” setting (the one that beeps) and touch the probes to the small metal test points on top of the fuse while it is still plugged in.
If the meter beeps, the fuse is good. If it remains silent, you have found your culprit. This method is much faster than pulling every single fuse one by one to inspect them manually.
Using a Test Light
If you don’t have a multimeter, a simple 12V test light is an affordable alternative. Ground the clip to a bare metal part of the frame and touch the tip to the fuse’s test points.
The light should glow on both sides of a healthy fuse. If it only glows on one side, the internal bridge is broken, and the fuse needs to be replaced immediately with an identical amperage rating.
Troubleshooting Electrical Issues Like a Pro
Fuses rarely blow for no reason. While a temporary power surge can occasionally pop a fuse, a recurring failure usually points to a deeper issue like a short circuit or a failing component.
If you replace a fuse and it blows again instantly, stop. This is a clear sign that a wire is touching the frame or a motor (like your window regulator) is drawing too much current because it is binding.
For off-roaders and overlanders, check your auxiliary lighting and winch wiring. Vibrations from rough trails can chafe wires against the chassis, leading to frequent fuse failures in the distribution box.
The “Smell Test” and Visual Cues
Sometimes, a failing relay—which is like a heavy-duty switch inside the fuse box—will give off a faint burning plastic smell. Relays can “stick” in the on or off position, causing batteries to drain overnight.
If your battery keeps dying, use your 2020 ford expedition fuse box diagram to identify the relays for the AC clutch or the fuel pump. If the relay feels hot to the touch while the car is off, it likely needs replacement.
Step-by-Step Guide to Replacing a Blown Fuse
Ready to fix it? Follow these steps to ensure a safe and successful repair. Safety is paramount when dealing with your vehicle’s electrical “nervous system.”
- Turn off the ignition: Ensure the key is out and all lights are switched off.
- Locate the panel: Use the locations mentioned above to find the correct box.
- Consult the diagram: Match the symptom (e.g., radio off) to the fuse number on the 2020 ford expedition fuse box diagram.
- Pull the fuse: Use a puller or pliers to remove the fuse straight out.
- Inspect: Look for a broken metal strip or a dark burn mark inside the plastic.
- Replace: Insert a new fuse of the exact same color and number.
- Test: Turn on the vehicle and see if the component functions again.
If the component still doesn’t work, you may be looking at a dead bulb, a broken wire, or a failed control module. At this point, consulting a certified mechanic is the best course of action.
