Mercedes-Benz Sprinter is a family of light commercial vehicles. First-generation models were produced in Germany from 1995 to 2006 as the successor to the TN platform, with production continuing in Argentina through 2011. In this article, we will take a detailed look at the power distribution and fuse box diagrams for the first-generation Mercedes-Benz Sprinter (body series W901 / W902 / W903 / W904 / W905) spanning the 1995 through 2006 model years.
Below you will find the locations and photographs of the power distribution boxes. The fuses protecting the “Cigarette Lighter” and “Fuel Pump” circuits are highlighted in bold.
Passenger Compartment Fuse Boxes
Two power distribution boxes are located in the passenger compartment to protect the vehicle's electrical circuits.
Fuse Box #1 (Main)
The main power distribution box is located beneath the steering column, behind a removable plastic cover panel.
The photograph above shows a representative overview.
