Learn about Citroën C3 2002-2008 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The Citroën C3 (2002-2008) comes in two major body styles: a 5-door hatchback and a convertible (C3 Pluriel). Known for its quirky design and practical dimensions, the C3 is popular for urban driving, offering compact size and ample interior space. Both body styles are equipped with essential electrical components such as power windows, central locking, and lighting systems, which rely heavily on the car’s fuse box and relays to function properly. The fuse box, typically located under the dashboard and in the engine compartment, houses the fuses and relays responsible for protecting and managing the car’s electrical circuits. Ensuring the fuse box and relays are well-maintained is crucial to prevent electrical malfunctions.

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.
