2017 Mercedes-Benz Metris Fuse Box Diagram & Amperage

Quick answer:

The 2017 Mercedes-Benz Metris has multiple fuse box locations to protect its various electrical systems. You'll find fuse boxes under the hood, behind the passenger's side kick panel, and in the cargo area on the driver's side.

Under-Hood Fuse Box

The under-hood fuse box is located on the driver's side of the engine compartment, near the battery. It houses fuses and relays for critical engine and drivetrain components, as well as some high-current accessories.

Passenger's Side Kick Panel Fuse Box

This fuse box is located behind the kick panel on the passenger's side of the cabin. It typically protects interior electrical components and accessories.

Cargo Area Fuse Box

The cargo area fuse box is located on the driver's side, behind a trim panel. This fuse box often contains fuses for rear-specific accessories, trailer wiring, and other convenience features.

Note: Fuse configurations can vary slightly depending on your Metris's specific trim level and optional equipment. Always consult the fuse diagram printed on the inside of your fuse box lid or your owner's manual for the most accurate information for your particular vehicle.

How to Test a Fuse

Testing a fuse is a straightforward process that can help you diagnose electrical issues. You'll need a fuse puller (usually found in the fuse box or tool kit) and a multimeter or a fuse tester.

1. Locate the Suspect Fuse: Refer to the fuse diagrams above or your owner's manual to identify the fuse associated with the malfunctioning component.
2. Turn Off the Ignition: Always turn off your vehicle's ignition and any accessories before working with fuses.
3. Remove the Fuse: Use the fuse puller to carefully remove the suspect fuse from its slot. Do not use pliers or other metal tools, as this can damage the fuse box.
4. Visually Inspect: Hold the fuse up to the light. If the metal wire or filament inside is broken or melted, the fuse is blown and needs to be replaced.
5. Test with a Multimeter (for non-obvious breaks):
   • Set your multimeter to the continuity setting (often indicated by a speaker or diode symbol).
   • Touch one probe to each metal blade of the fuse.
   • A healthy fuse will show continuity (the multimeter will beep or display a very low resistance reading). If there's no continuity, the fuse is blown.
6. Test with a Fuse Tester: Insert the fuse into the designated slot on the fuse tester. If the light on the tester illuminates, the fuse is good. If not, it's blown.
7. Replace (if necessary): 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 amperage rating, as this can lead to serious electrical damage or fire.
8. Reinstall Fuse Box Cover: Ensure the fuse box cover is securely reinstalled to protect the fuses from dirt and moisture.

Common Blown Fuses on This Vehicle

While any fuse can blow, some are more prone to failure due to their role in frequently used systems or high-current components. On the 2017 Mercedes-Benz Metris, some common fuses that may blow include:

• Cigar Lighter/12V Power Outlets: These fuses (often 15A or 20A, like F2 in the passenger's side fuse box) frequently blow due to overcurrent from charging multiple devices or using high-power accessories. If your phone charger or other accessories aren't working, check this first.
• Blower Motor: The blower motor fuse (often 30A, like F6 under the hood) can blow, especially if the blower motor is old, drawing excessive current, or if there's debris obstructing its operation. If your HVAC fan isn't working, this is a prime suspect.
• Headlights/Tail Lights: While less common, a short circuit in a bulb or wiring can cause these fuses (e.g., F7, F8, F9, F10 under the hood, and F3, F4 in the passenger's side) to blow. If one or more of your exterior lights aren't working, check the corresponding fuse.
• Radio/Infotainment: If your radio or infotainment screen suddenly goes blank, check the fuse dedicated to this system (e.g., F1 in the passenger's side fuse box). This could be due to a spike in power or an internal component issue.

When a fuse blows, it's essential to not only replace it but also to understand why it blew. If a fuse repeatedly blows, it indicates an underlying electrical problem that needs to be diagnosed by a qualified technician.
