The Chevrolet Bolt EUV (2022-2023) is an electric utility vehicle with a range of up to 247 miles on a single charge. It offers spacious seating, advanced technology, and GM’s Super Cruise hands-free driving system for highway use. Its key features include a 10.2-inch touchscreen, wireless Apple CarPlay/Android Auto, and available adaptive cruise control.
The fuse box and relays are integral to the Bolt EUV’s electrical systems, ensuring the smooth operation of its advanced technology and drivetrain. The fuse box, located under the hood and in the interior, protects crucial components like the electric motor, infotainment, and climate control by preventing power surges.
The relays manage high-power functions, such as the electric drivetrain and battery systems, by allowing low-power controls to operate these high-power systems safely. If a relay fails, it may cause issues like charging problems or impact the vehicle’s motor performance.
Routine checks of the fuses and relays ensure that the Bolt EUV’s features and electric systems operate effectively, keeping the vehicle’s tech and powertrain functioning as designed.

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.
