Learn about Dodge Ram Cargo Van or C/V Tradesman 2012-2015 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.

The Dodge Ram Cargo Van, also known as the C/V Tradesman (2012-2015), is designed primarily for commercial use, featuring a spacious cargo area for transporting goods or equipment. It retains the body style of a minivan but removes the rear seats, optimizing space for businesses needing a reliable work vehicle. The vehicle is equipped with sliding side doors and rear cargo doors, making loading and unloading convenient.

The van’s electrical system, which powers various features such as lights, power windows, and climate control, relies heavily on its fuse box and relay system. The fuse box, located under the dashboard or hood, protects the electrical circuits from damage caused by overloads. Relays, housed near the fuse box, control high-power systems such as the fuel pump, starter, and HVAC fan. Proper maintenance of the fuse box and relays is essential to avoid electrical issues and ensure the van runs smoothly, keeping all its work-related features functional.

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.
