The Buick Encore, spanning from 2013 to 2022, represents Buick’s commitment to blending versatility, efficiency, and modern technology in the compact SUV segment. Its advanced electrical system includes essential components such as the fuse box and relays.
The fuse box in the Buick Encore 2013-2022 houses fuses designed to protect electrical circuits from overloads and short circuits, ensuring the safety of critical components like headlights, taillights, and power windows. Relays, serving as electrically controlled switches, manage the flow of electricity to systems such as the starter motor, fuel pump, and cooling fans, ensuring efficient and reliable operation.
Additional sophisticated electrical components in the Buick Encore of this era include advanced infotainment systems, climate control features, power-adjustable seats, and advanced driver assistance systems (ADAS). These features rely on a robust electrical infrastructure to enhance comfort, convenience, and safety for occupants.
Understanding the layout and function of the fuse box and relays is crucial for maintaining and troubleshooting the Buick Encore 2013-2022’s electrical systems. Regular inspection and maintenance of these components help ensure the vehicle’s reliability and performance, maintaining its reputation as a versatile and dependable SUV in Buick’s lineup.

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.
