The Chevrolet Traverse, produced from 2018 to 2022, is a midsize SUV that offers spacious seating, advanced safety features, and modern technology, making it a popular choice for families. Integral to the operation of the Traverse is its electrical system, which relies heavily on the fuse box and relays to function effectively and safely.
The fuse box in the Chevrolet Traverse is designed to protect the vehicle’s various electrical circuits. These circuits control essential systems such as engine management, lighting, infotainment, climate control, and power accessories, including windows and locks. Typically, the Traverse features two main fuse boxes: one located inside the cabin, often under the dashboard or in the center console, and another in the engine compartment. The interior fuse box manages many of the comfort and entertainment features, while the engine compartment fuse box is responsible for more critical systems, including those related to the engine and transmission.
Each fuse in these boxes is responsible for protecting a specific circuit. When a circuit experiences an overload or short circuit, the corresponding fuse will “blow,” effectively cutting off the power to prevent damage to the system or potential electrical fires. If certain features, such as the audio system or headlights, stop working, checking the related fuse is a crucial first step in diagnosing the problem.
Relays in the Chevrolet Traverse serve as electrically operated switches that control high-current systems like the starter motor, fuel pump, and cooling fans. These relays allow the vehicle to use lower-power circuits to control high-demand systems, thus preventing overloads in the vehicle’s wiring and switches. This ensures both reliability and safety in the vehicle’s electrical systems.
Maintaining the fuse box and relays in the Traverse is key to preventing electrical issues. Regular inspections can help detect blown fuses or failing relays before they cause significant problems. If a fuse needs replacing, it’s vital to use one with the correct rating to ensure proper protection. Likewise, a faulty relay should be replaced promptly to prevent system failures, such as the engine failing to start or overheating due to a non-functional cooling fan.
By understanding the importance of the fuse box and relays, owners can better maintain their Chevrolet Traverse, ensuring all systems operate smoothly and reliably. This contributes to a safe, efficient, and comfortable driving experience, highlighting the vehicle’s reputation for reliability and family-friendly features.

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.
