Learn about Dodge Ram ProMaster City 2015-2018 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The Dodge Ram ProMaster City (2015-2018) is a compact commercial van available in two main body styles: the Cargo Van and the Passenger Wagon. The Cargo Van is designed for businesses and tradespeople, offering a spacious cargo area with up to 131.7 cubic feet of storage space, while the Passenger Wagon seats up to five and is ideal for small families or work crews. Both versions feature a compact size, making them highly maneuverable in urban environments, yet they still offer impressive payload and towing capacities.
The vehicle’s electrical system, including the fuse box and relays, plays a crucial role in controlling various functions like the lighting, power windows, and climate control. The fuse box is located in the engine compartment, and it houses fuses that protect the vehicle’s electrical circuits from overload. Relays are also located near the fuse box and control high-power components like the fuel pump and starter. Ensuring these components are in good condition helps maintain the van’s reliability, particularly for commercial purposes where downtime can affect productivity.

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.
