The Chevrolet Sonic, also known as the Aveo in some markets, produced between 2012 and 2020, is a popular subcompact car praised for its stylish design, efficient performance, and practical features. A critical part of its functionality is its electrical system, which relies heavily on fuse boxes and relays to operate various components safely and effectively.

The fuse box in the Chevrolet Sonic/Aveo is located in two primary areas: one in the engine compartment and another inside the cabin, typically on the driver’s side. The engine compartment fuse box handles high-power components like the engine and ABS, while the interior fuse box manages lower-power systems such as lighting, climate control, and infotainment. Each fuse in these boxes is designed to protect its respective circuit by “blowing” in case of an electrical fault, preventing damage to other components.

Relays in the Sonic/Aveo serve as electrically operated switches for high-current systems, such as the starter, cooling fans, and fuel pump. By isolating these high-power circuits, relays help ensure safe and efficient operation. Regular checks and maintenance of fuses and relays are essential for the vehicle’s reliability, helping prevent electrical issues and ensuring smooth performance.

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.
