The Chevrolet Aveo (2002-2006) is a compact, fuel-efficient car designed for urban commuting. It features a simple, practical interior with power windows, air conditioning, and basic infotainment options. Its small but efficient engine makes it an economical choice for daily driving.
The fuse box, located under the dashboard and in the engine compartment, protects vital electrical components like the headlights, radio, and wipers. A blown fuse can disable these systems, requiring a simple replacement to restore functionality.
The relays in the Aveo control critical systems such as the fuel pump, starter motor, and cooling fan. These relays function like electrical switches, allowing low-power circuits to control high-power components. If a relay malfunctions, it can lead to issues like the car failing to start or the engine overheating.
Regular maintenance of the fuse box and relays ensures that the Aveo’s electrical systems continue to operate smoothly, keeping its essential functions running without interruption.

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.
