Learn about Citroën C3 2009-2016 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The Citroën C3 (2009-2016) is available in various body styles, including hatchback and convertible, offering a combination of practical urban driving and stylish design. The hatchback is popular for its compact dimensions, making it suitable for city commuting, while the convertible version features a panoramic windscreen, giving it a more open and airy feel.
An important aspect of maintaining this car is understanding its electrical components, especially the fuse box and relay, which control essential systems like lighting, air conditioning, and engine management. The fuse box, located under the dashboard or in the engine compartment, houses critical fuses that protect the electrical circuits. Relays, often near the fuse box, help manage high-power circuits like the starter or fuel pump. Regular inspection ensures the car’s electrical systems run smoothly.

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.
