The 2012 Chevrolet Aveo features a compact yet practical design, making it ideal for city driving. It comes equipped with efficient four-cylinder engines, comfortable seating for five, and modern conveniences like power windows and air conditioning. Key safety features include airbags and anti-lock brakes, contributing to its overall reliability.
The fuse box, located under the dashboard and in the engine compartment, protects critical electrical components such as the lights, radio, and power windows. If a fuse blows, it interrupts power to the corresponding system, ensuring no further electrical damage occurs.
The relays manage power distribution to vital functions such as the fuel pump, cooling fan, and air conditioning system. These relays act as electrical switches that control high-power circuits. A faulty relay can cause issues such as the engine failing to start or the cooling system malfunctioning.
Regular inspection and maintenance of the fuse box and relays are essential to ensure the Aveo’s electrical systems function properly, safeguarding the vehicle’s performance and overall driving experience.

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.
