Chevrolet Trax (2018-2022) fuse box and relay Diagrams

The Chevrolet Trax, produced from 2018 to 2022, is a compact SUV designed for urban driving with a focus on practicality, efficiency, and modern features. The electrical system in the Trax is central to its functionality, and the fuse box and relays are key components that ensure the vehicle’s various electrical systems operate smoothly.

The fuse box in the Chevrolet Trax is responsible for protecting the vehicle’s electrical circuits. These circuits control essential systems such as the engine management, lighting, infotainment, climate control, and power accessories like windows and locks. The Trax typically has two main fuse boxes: one located inside the cabin, usually under the dashboard on the driver’s side, and another in the engine compartment. The interior fuse box manages many of the vehicle’s comfort and convenience features, while the engine compartment fuse box handles more critical systems, such as those related to the engine and transmission.

Each fuse within the box is assigned to a specific electrical circuit and is designed to “blow” if there is an overload or short circuit. This action prevents damage to more expensive and sensitive components by cutting off the power to the affected circuit. For instance, if a particular system like the power windows or headlights stops working, checking the related fuse is the first step in troubleshooting the issue.

Relays in the Chevrolet Trax are electrically operated switches that control the power supply to high-current systems. These include the starter motor, fuel pump, cooling fans, and other power-intensive components. Relays are crucial because they allow a low-power control circuit to operate a high-power system without overloading the vehicle’s smaller switches and wiring.

Regular inspection and maintenance of the fuse box and relays in the Chevrolet Trax are essential for preventing electrical problems. If a fuse blows, replacing it with the correct type and rating is important to restore functionality to the affected system. Similarly, if a relay fails, it can cause more significant issues, such as preventing the engine from starting or causing the cooling system to malfunction.

By understanding the role of the fuse box and relays, Trax owners can better maintain their vehicle’s electrical system, ensuring that all features operate reliably and efficiently, contributing to a safe and comfortable 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.
