Find fuse box and relay locations for the 2003-2006 Dodge Sprinter with detailed diagrams. Ensure optimal performance of electrical systems in your Sprinter.
The Dodge Sprinter (2003-2006) is a versatile, full-size van designed to accommodate a variety of commercial and personal needs. Available in multiple body styles, including cargo, passenger, and chassis cab configurations, it offers different roof heights and wheelbases to provide ample interior space and flexibility for hauling goods or transporting people. The Sprinter’s design prioritizes utility and practicality, making it popular among businesses and fleet operators.
To support its numerous features, the Sprinter’s electrical system relies on strategically placed fuse boxes and relays that help manage its electronic functions. The primary fuse box is typically located under the driver’s seat, while relays for larger electrical components, such as the starter and fuel pump, are found in the same compartment. Keeping these fuses and relays in good condition is crucial to ensuring the vehicle’s dependable performance, especially for commercial use where reliability is essential.

WARNING
- Never replace a fuse with one that has a higher amperage rating.
- A fuse with a too-high amperage could damage the electrical part and cause a fire.
- On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
- If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
- Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.
