Hey guys! Finding the fuse box in your 2020 Sprinter can feel like a mini-quest, but don't worry, I'm here to guide you through it. Knowing the location and how to access it is super useful for troubleshooting electrical issues, replacing a blown fuse, or just doing some general maintenance. This guide will walk you through the exact spots where these fuse boxes are hiding in your 2020 Sprinter. Let's dive in!

Why Knowing Your Fuse Box Location Matters

Okay, so why should you even care about where the fuse box is? Well, fuses are like the unsung heroes of your van's electrical system. They protect sensitive components from power surges by blowing out and cutting off the circuit when things get overloaded. Without them, you could be looking at some serious damage to expensive electronics. Being able to quickly locate and access the fuse box means you can:

• Quickly fix problems: A blown fuse can cause anything from a non-working radio to a dead headlight. Knowing where the fuse box is lets you quickly identify and replace the faulty fuse, getting you back on the road faster.
• Save money: Instead of rushing to a mechanic for every minor electrical issue, you can troubleshoot and fix simple problems yourself. This can save you a ton of money on labor costs.
• Prevent further damage: Ignoring a blown fuse or an electrical problem can sometimes lead to more significant damage down the road. Addressing issues promptly can prevent these problems from escalating.
• Peace of mind: When you're traveling, especially in remote areas, knowing you can handle basic electrical repairs yourself gives you a huge sense of security.

Understanding Fuses: Fuses are designed to protect your vehicle's electrical system by interrupting the flow of electricity when there's an overload or short circuit. Each fuse is rated for a specific amperage, which indicates the maximum current it can handle. Using the correct amperage fuse is crucial; using a higher amperage fuse can allow too much current to flow, potentially damaging components, while a lower amperage fuse will blow too easily. Regularly inspect your fuses for any signs of damage or corrosion, and always replace a blown fuse with one of the same amperage. Also, keep a spare set of fuses in your vehicle, it's a lifesaver on the road!

Primary Fuse Box Location: Under the Driver's Seat

The most common location for the main fuse box in the 2020 Sprinter is under the driver's seat. Here’s how to access it:

1. Prepare the Area: First, clear the area around the driver's seat. You'll need some room to maneuver. Make sure the parking brake is engaged and the ignition is off for safety.
2. Locate the Cover: Look for a plastic cover on the base of the driver's seat, usually on the side facing the center of the van. This cover might be held in place by clips or screws.
3. Remove the Cover: If the cover has clips, gently pry it off using a flathead screwdriver or a trim removal tool. If it has screws, unscrew them and then remove the cover.
4. Identify the Fuse Box: Once the cover is off, you should see a rectangular box with a bunch of fuses inside. This is the main fuse box. You might also find a fuse diagram attached to the inside of the cover or on the fuse box itself. This diagram is super helpful for identifying which fuse controls which component.

Inside this primary location, you’ll find fuses that control a wide array of functions, from your headlights and windshield wipers to the central locking system and interior lights. Make sure to consult your Sprinter's manual or the fuse diagram to accurately identify the fuse you need to check or replace. Sometimes, the diagram can be a bit cryptic, so take your time and double-check before pulling any fuses. Proper lighting is also key, so use a flashlight or headlamp to get a clear view of the fuse box.

Safety First: Before you start poking around in the fuse box, always turn off the ignition and remove the key. This prevents any accidental electrical shocks or shorts. When removing a fuse, use a fuse puller tool (often included in the fuse box) to avoid damaging the fuse or the surrounding components. If you don't have a fuse puller, needle-nose pliers can work in a pinch, but be extra careful not to break the fuse. After replacing a fuse, always test the circuit to make sure it's working correctly. If the fuse blows again immediately, there's likely a more significant electrical problem that needs professional attention.

Secondary Fuse Box Location: Under the Dashboard

Some 2020 Sprinter models also have a secondary fuse box located under the dashboard, typically on the driver's side. This fuse box usually houses fuses for accessories and other vehicle functions. Here’s how to find it:

1. Get Comfortable: You'll need to get down low to access this fuse box. Clear out any items from the driver's side footwell to give yourself some room to work.
2. Locate the Panel: Look for a small access panel under the dashboard, usually near the steering column or to the left of the pedals. It might be labeled or have a small indentation to help you open it.
3. Open the Panel: The panel might have a latch or require a screwdriver to open. Gently release the latch or unscrew the panel to access the fuse box behind it.
4. Identify the Fuse Box: Once the panel is open, you should see a smaller fuse box with various fuses. Again, there might be a fuse diagram attached to the panel or the fuse box itself. Take your time to get familiar with the layout.

This secondary fuse box often contains fuses related to your Sprinter's entertainment system, diagnostic systems, and other convenience features. For example, you might find the fuse for your radio, navigation system, or even the OBD-II port here. These fuses are just as important as the ones in the primary fuse box, so it's good to be familiar with their location and function. Some Sprinter models might have additional relays or modules in this area as well, so be careful not to disturb anything you're not familiar with.

Troubleshooting Tips: If you're having trouble locating the fuse box, consult your Sprinter's owner's manual. It should have a detailed diagram showing the exact location of all fuse boxes and components. If you're still unsure, you can also try searching online forums or contacting a Sprinter dealership for assistance. Before you start any electrical work, disconnect the negative terminal of your Sprinter's battery. This will help prevent any accidental electrical shocks or shorts. When replacing a fuse, always use the correct amperage rating. Using a fuse with a higher amperage can damage your Sprinter's electrical system.

Fuse Box Diagram and Fuse Types

So, you've found the fuse box(es), but now what? The key to successfully troubleshooting fuse-related issues is understanding the fuse box diagram and the different types of fuses.

Understanding the Fuse Box Diagram

The fuse box diagram is your roadmap to understanding which fuse controls which component. It's usually located on the inside of the fuse box cover or in your Sprinter's owner's manual. The diagram will show a schematic of the fuse box, with each fuse labeled with a number or letter. Next to each label, there will be a description of the component that the fuse protects. For example, you might see labels like
