Find fuse box and relay locations for the 2021-2024 Chevrolet TrailBlazer, with diagrams for reference. Key guide to maintain reliable electrical system performance.
The Chevrolet TrailBlazer (2021-2024) is a compact SUV with a sporty, modern design that appeals to drivers seeking a blend of practicality and style. Available in multiple trims, including the sporty RS and off-road-oriented ACTIV, the TrailBlazer offers both two-tone and monochromatic options, emphasizing its versatile and youthful character. With ample interior space, it comfortably accommodates five passengers and offers flexible cargo options, making it ideal for urban driving and weekend getaways.
Supporting the TrailBlazer’s advanced technology and convenience features, the electrical system depends on well-placed fuse boxes and relays. The main fuse box is located under the hood, while a secondary fuse box is typically found within the cabin, near the driver’s side. Relays within these boxes control high-power functions, such as the starter, headlights, and cooling systems, ensuring these essential features work seamlessly. Routine inspections of the fuse box and relays help maintain the vehicle’s reliability and performance.

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.
