Chevrolet Trax (2013-2017) fuse box and relay Diagrams
The Chevrolet Trax, produced from 2013 to 2017, is a compact SUV designed to meet the demands of urban driving with its practical size, fuel efficiency, and versatile features. The vehicle’s electrical system is vital for operating its numerous functionalities, and the fuse box and relays play critical roles in maintaining and protecting this system.
The fuse box in the Chevrolet Trax is essential for safeguarding the vehicle’s electrical circuits. These circuits power critical systems, including engine management, lighting, climate control, infotainment, and various power accessories such as windows and locks. Typically, the Trax has two main fuse boxes: one located inside the cabin, generally beneath the dashboard on the driver’s side, and another in the engine compartment. The interior fuse box controls many of the comfort and convenience features, while the engine compartment fuse box handles the more crucial systems related to engine and powertrain operation.
Each fuse in these boxes is designed to protect a specific electrical circuit. When there’s an overload or a short circuit, the fuse will “blow,” cutting off power to prevent damage to the circuit and its connected components. This safety feature is crucial for preventing electrical fires and costly damage. For example, if the headlights or air conditioning stop working, the first step in troubleshooting should be to check the corresponding fuse.
Relays in the Chevrolet Trax are electrically operated switches that manage the power supply to high-current systems, such as the starter motor, fuel pump, and cooling fans. Relays allow these systems to be controlled by lower-power circuits, ensuring that the vehicle’s electrical wiring and switches are not overloaded. This setup enhances both the reliability and safety of the vehicle’s electrical systems.
Regular checks of the fuse box and relays are crucial for maintaining the Trax’s electrical integrity. If a fuse blows or a relay fails, replacing it with the correct specification is essential to restore the system’s functionality. Issues with relays can lead to more significant problems, such as preventing the engine from starting if the starter relay is compromised or overheating if the cooling fan relay fails.
By understanding and maintaining these components, owners can ensure their Chevrolet Trax runs efficiently and safely, with all electrical systems functioning as intended to provide a reliable 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.
