The Buick Verano, produced between 2016 and 2017, continues to embody Buick’s commitment to luxury, comfort, and reliability in the compact sedan market. This model is equipped with a range of sophisticated electrical components, including the fuse box and relay, which are essential for the proper functioning of various vehicle systems.
The fuse box in the Buick Verano 2016–2017 houses multiple fuses that protect individual electrical circuits from overloads and short circuits. These fuses are critical in preventing damage to sensitive components such as the lighting system, climate control, and audio system. Understanding the location and purpose of each fuse can facilitate efficient troubleshooting and maintenance.
Relays in the Buick Verano act as electrical switches that control the activation of various components, such as the starter motor, fuel pump, and cooling fan. They play a pivotal role in ensuring that electricity is delivered to these components as needed, enhancing overall vehicle performance and reliability.
In addition to the fuse box and relay, the Buick Verano 2016–2017 incorporates advanced electrical features designed to enhance comfort and convenience for both drivers and passengers. These may include technologies such as keyless entry, touchscreen infotainment systems, and driver assistance features like lane departure warning and rearview cameras.

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.
