Chevrolet Volt (2011-2015) fuse box and relay Diagrams
The Chevrolet Volt (2011-2015) was a pioneering plug-in hybrid vehicle, blending electric power with a gasoline engine to deliver impressive efficiency and range. This innovative vehicle relies heavily on its electrical system, where the fuse box and relay components play essential roles in maintaining the car’s functionality and safety.
In the Chevrolet Volt, the fuse box is responsible for protecting various electrical circuits throughout the vehicle. These circuits control key systems such as the battery management system, electric motor, infotainment, lighting, and climate control. The Volt typically has multiple fuse boxes: one located inside the cabin, usually under the dashboard or in the glove compartment, and another in the engine compartment. Each fuse is designed to interrupt the circuit in the event of an electrical overload or short circuit, thereby preventing damage to critical components and ensuring the vehicle’s electrical system remains safe.
Relays in the Chevrolet Volt are critical for managing high-current circuits that are necessary for the operation of components such as the electric motor, cooling fans, fuel pump, and power windows. These relays act as switches that allow a small electrical signal to control a larger flow of current, thereby enabling the vehicle’s various systems to operate efficiently and reliably. Without properly functioning relays, the Volt’s complex electrical systems, including the hybrid powertrain, would be unable to perform optimally.
Maintenance of the fuse box and relays in the Chevrolet Volt is crucial for avoiding electrical issues that could compromise the vehicle’s performance. Regularly checking the fuses and relays can help identify potential problems before they lead to more serious failures, such as a malfunctioning electric motor, non-operational climate control, or lighting issues. If a fuse blows or a relay fails, it’s important to replace it with a component of the correct specification to ensure the continued safe and efficient operation of the vehicle.
Given the Chevrolet Volt’s reliance on its electrical systems, understanding the roles of the fuse box and relays is key to maintaining the car’s hybrid functionality. Proper upkeep of these components ensures the Volt’s advanced systems work seamlessly, allowing for a smooth and reliable 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.
