Quick Answer
Your 2017 Mercedes-Benz Sprinter has three main fuse box locations:
- Driver's Side Dash: Located on the driver's side, accessible when the door is open.
- Under the Hood: A large fuse and relay box is located on the driver's side of the engine bay, near the battery.
- Driver's Seat Pedestal: The main fuse panel is located at the base of the driver's seat, requiring a cover to be removed.
Always confirm fuse locations with the diagram printed inside your vehicle's fuse box covers, as configurations can vary based on trim level and optional equipment.
Driver's Seat Pedestal Fuse Box (Main Fuse Panel)
This is the primary fuse panel for the 2017 Sprinter. It's located at the base of the driver's seat. You'll need to remove a plastic cover to access it. This panel is divided into blocks F1 through F4.

How to Test a Fuse
A blown fuse is a common and easy-to-fix issue.
- Turn Off the Vehicle: Ensure the ignition is off before inspecting fuses.
- Locate the Fuse Box: Find the correct fuse box based on the malfunctioning component.
- Remove the Fuse: Use the plastic fuse puller tool often found inside the fuse box lid. If a puller isn't available, small needle-nose pliers will work, but be gentle.
- Inspect the Fuse: Hold the fuse up to the light. Inside a good fuse, you will see a small metal wire that is intact. In a blown fuse, this wire will be broken or melted.
- Replace if Necessary: If the fuse is blown, replace it with a new fuse of the exact same amperage (Amp) rating. Using a higher-amp fuse can cause a fire. The amp rating is printed on top of the fuse and is also color-coded.
Common Blown Fuses on the 2017 Sprinter
- Cigar Lighter / 12V Power Outlet Fuse (F1/7): This is one of the most common fuses to blow. It often happens when a faulty phone charger or other accessory is plugged in. Before replacing the fuse, unplug everything from the power outlets to ensure a faulty device isn't the cause.
- Blower Motor Fuse (F1/1): If your cabin fan stops working on all speeds, this fuse is the first thing to check. If the new fuse blows again quickly, it may indicate a failing blower motor resistor or a blower motor that is drawing too much current and needs replacement.
- Fuel Pump Fuse (F1/8): If your Sprinter cranks but won't start, check this fuse. A blown fuel pump fuse can be a sign of a failing fuel pump. Listen for a humming sound from the fuel tank area when you first turn the key; if you hear nothing and the fuse is good, the fuel pump relay (R3) is the next logical component to check.
- Trailer Brake/Lights Fuse (F1/6): If you are experiencing issues with your connected trailer's lights or brakes, check this fuse first. Often, issues with trailer wiring (corrosion, shorts) are the cause. Inspect the trailer connector on the van and the trailer plug itself for any damage or green corrosion before replacing the fuse.
If you've checked the fuses and are still having trouble, or if a fuse repeatedly blows, it's time for a professional diagnosis. A deeper electrical issue may be the cause.

Before you pull a fuse on the 2017 Mercedes-Benz Sprinter
- Use the label printed on the panel cover or the owner's manual for your exact build. Layouts change with options, model year and build date, so a chart for another truck can be wrong.
- Replace a blown fuse only with the same amp rating. A larger fuse can let wiring overheat.
- A fuse that blows again right away means a short or failing component downstream. Find the cause before replacing it again.
- A good fuse doesn't prove the circuit works — relays, grounds and connectors fail too.
- Disconnect the battery before working near high-current fuses or cables.
