Mercedes-Benz Fuse Box and Relay Diagrams - Complete Guide

The fuse box in a Mercedes-Benz is a critical component that serves as the central hub for the vehicle's electrical systems. Understanding the fuse box diagram is essential for diagnosing and fixing electrical issues, whether you are a seasoned mechanic or a car enthusiast. By knowing which fuse corresponds to each component, you can efficiently handle blowouts or replacements without professional help, saving both time and money.

Why You Need a Fuse Box Diagram

A fuse box diagram acts as a roadmap to your vehicle's electrical system. It displays which fuses are linked to specific electronics like lights, radio, and air conditioning. If you experience any electrical malfunctions, consulting the diagram can quickly direct you to the problematic fuse. This is especially useful for DIY repairs and routine maintenance.

  • Headlights: Fuse related to the car’s front and rear external lighting.
  • Ignition system: Controls the ignition switch and starter.
  • Power windows: Fuse that handles the electric windows.
  • Radio and infotainment: Controls the entertainment system of the vehicle.

Steps to Replace a Fuse

  1. Turn off your vehicle and remove the key from the ignition.
