The Mercedes-Benz W220 S-Class, particularly the high-performance S55 AMG model, is known for its complex electrical system. Finding the correct fuse chart for a 2002 S55 AMG (W220) can be challenging. While a 2005 W220 fuse diagram might offer some guidance, the 2003-2006 models, including the 2002 S55 AMG, have four distinct fuse panels. Understanding their locations is crucial for troubleshooting electrical issues.
Decoding the W220’s Fuse Panel Locations (2003-2006)
The 2002 S55 AMG, like other W220 models from 2003-2006, features fuse panels in these key areas:
- Engine Compartment (Left & Right): Two fuse boxes are situated on either side of the engine compartment, typically near the firewall. The driver’s side (left) often houses fuses for components like power windows (e.g., Fuse 13 for the driver’s side window in a 2005 model). Numbered slots on the panel, revealed after removing the cover, aid in fuse identification.
- Under Rear Seat (Right): Access this fuse panel by removing the panel surrounding the right rear courtesy light in the floor space.
- Dashboard: Located on the right side for left-hand drive (LHD) cars and the left side for right-hand drive (RHD) cars, this panel can be particularly tricky to find. It often contains fuses numbered 78 through 86. Consulting the owner’s manual and the vehicle diagram on the fuse chart is essential for locating this hidden panel.
Beyond the Standard Fuse Panels: High-Amperage Fuses
In addition to the four primary fuse panels, the W220 includes:
- Rear Quarter Panel (Right): Behind the trunk lining, this fuse box houses a 150-amp fuse responsible for powering the SAM (Signal Acquisition Module) units.
- Right Footwell: Another fuse box is located in the right footwell area.
These high-amperage fuses are generally not the standard easy-to-replace type. Replacing them often necessitates purchasing the entire fuse box.
Accessing the Correct 2002 S55 AMG Fuse Diagram
While a 2005 W220 fuse diagram might provide a general overview, it’s crucial to obtain the specific diagram for your 2002 S55 AMG. The part number for the fuse chart is usually printed on the diagram itself. Consult your owner’s manual or contact a Mercedes-Benz dealership to order the correct diagram for your specific model year. Online forums dedicated to the W220 S-Class may also offer valuable resources and information regarding fuse box locations and diagrams. Understanding your vehicle’s electrical system is key to maintaining its optimal performance. Always refer to the correct documentation before attempting any electrical repairs.
