Learn about Chevrolet Blazer EV 2024 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The 2024 Chevrolet Blazer EV is an all-electric midsize SUV that combines a modern, sporty design with advanced technology. Available in various trims, including performance-oriented SS and more practical configurations, the Blazer EV offers a range of body styles to suit diverse preferences. The exterior features sharp lines, bold LED lighting, and a sleek, aerodynamic profile, while the interior is spacious and tech-focused, designed to cater to both family needs and adventurous drivers.
Although the Blazer EV operates on an electric platform, it still utilizes fuse boxes and relays to manage and protect its electrical systems. The fuse box, often located under the hood or within the cabin, regulates and safeguards circuits powering everything from lighting to infotainment and safety features. Relays near these fuse boxes help manage higher-current components, such as the motor control system and climate functions. Regular inspection of these components is essential for ensuring consistent performance of the Blazer EV’s electrical systems.

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.

The instrument panel fuse block is to the right of the glove box.
To Access the Fuses:
- Remove the panel, starting at the top.
- Once the panel clips disengage, the tabs along the bottom of the door can disengage from the instrument panel to remove the door.
- To reinstall the door, place the bottom tabs into the slots, and rotate the door into position, engaging the clips.
Underhood Compartment Fuse Block:
To Access:
- The underhood compartment fuse block is below the underhood access covers. The covers interlock with various tabs and clips, and must be removed and replaced in a certain order. The center covers (3) and (4) and edge covers (1) must be removed before removing the right side cover (2).
- To open the fuse block cover, press the clips at the side and back and pull the cover up.
