Learn about Citroën C2 2003-2009 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The Citroën C2 (2003-2009) is a compact three-door hatchback that offers both practicality and sporty flair. Its two main versions are the standard model and the high-performance VTS trim. The standard model appeals to city drivers with its compact design and efficient fuel economy, while the VTS version targets enthusiasts with a sportier suspension, more powerful engine, and aggressive styling.
Key features include a split-folding rear seat for added versatility, digital instrumentation, power windows, and advanced safety features like ABS and airbags. The C2’s electrical components, such as the wipers, headlights, and air conditioning, are controlled through its fuse box and relay system. The fuse box is typically found under the dashboard or within the engine bay, safeguarding electrical circuits. The relays, located near the fuse box, control power to high-demand components like the starter and fuel pump. Regular inspection of the fuse box and relays is essential to ensure these electrical systems function correctly, as blown fuses or faulty relays can lead to malfunctions in key vehicle systems.

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.
