Learn about Citroën Relay 2006-2014 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The Citroën Relay (2006-2014) is primarily available as a van with multiple body styles, including panel vans, chassis cabs, and minibuses. It is designed for versatility, offering various lengths and roof heights, making it suitable for commercial purposes. Key features include robust cargo space, modern infotainment systems, and safety options like ABS and airbags.
The fuse box, located under the dashboard and under the hood, protects essential systems such as lights, air conditioning, and the infotainment system from electrical surges. When a fuse blows, it interrupts power to prevent damage to these systems.
The relays control larger components like the fuel pump, windshield wipers, and engine cooling fan. They act as intermediaries that allow small electrical signals to manage larger electrical loads. If a relay fails, it can cause problems like the engine failing to start or cooling fans not operating properly.
Maintaining the fuse box and relays in the Citroën Relay ensures the vehicle’s electrical systems remain functional, which is crucial for the van’s performance and safety.

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.
