Key Fuse Box Locations for the 2007 S550 Radio

In the 2007 Mercedes S550, fuses are typically located in multiple fuse boxes. The main locations relevant to the radio are:. For more related activities, check out our Mk6 Golf Fuse Box Diagram.

  • Driver’s Side Fuse Box (Under the Dashboard): This is often the primary location for radio-related fuses. Access is usually gained by removing a panel on the driver’s side, near the footwell.
  • Passenger’s Side Fuse Box (Under the Dashboard): Another possible location, accessible in a similar manner to the driver’s side box.
  • Engine Compartment Fuse Box: While less likely for the primary radio fuse, this box might contain fuses related to the amplifier or other audio system components.
  • Rear Fuse Box (Trunk Area): Some models might have a fuse box in the trunk, potentially housing fuses for the amplifier or other rear-mounted audio equipment.


Important Note: Always consult your vehicle’s owner’s manual for the exact fuse locations and fuse assignment charts. These charts are often also located inside the fuse box covers themselves. Fuse diagrams change between model years and even within a single model year.

Practical Application

Follow these steps to locate and replace the radio fuse in your 2007 Mercedes S550:

  1. Consult Your Owner’s Manual: Identify the exact fuse location for the radio based on the fuse chart. The chart specifies fuse number and amperage.
  2. Locate the Fuse Box: Find the relevant fuse box (Driver’s side, Passenger’s side, Engine compartment, or Trunk) as indicated by the manual.
  3. Open the Fuse Box: Use a screwdriver or trim removal tool to carefully open the fuse box cover.
  4. Identify the Fuse: Using the fuse chart, locate the radio fuse. It will typically be labeled on the chart.
  5. Inspect the Fuse: Carefully remove the fuse using a fuse puller (usually located in the fuse box). Examine the fuse. If the small wire inside the fuse is broken, the fuse is blown.
  6. Replace the Fuse: Replace the blown fuse with a new fuse of the exact same amperage. Using a fuse with a higher amperage can cause serious damage to the vehicle’s electrical system.
  7. Test the Radio: Turn on the ignition and test the radio to see if it’s working.
  8. If the Fuse Blows Again: If the new fuse immediately blows, there is likely a short circuit in the radio wiring or within the radio itself. Further diagnosis by a qualified technician is recommended.
