2024 Chevrolet Blazer EV Fuses and Fuse Box | Replacing a Blown Fuse
The fuse box is one of the most important parts of the 2024 Chevrolet Blazer EV’s electrical system. This important part is meant to protect the car’s computer systems by housing several fuses, each of which is responsible for keeping certain circuits safe from electrical overloads or faults. When placed in the right place inside the car, the fuse box acts as a central hub for managing and spreading electricity. As a watchdog, it keeps important parts like lights, power windows, and other electronic features from getting damaged. When there is an electrical problem, it is very important to know how to find and repair a blown fuse. To do this, you need to find the bad fuse, which can be seen as having a broken filament or a discolored look, and replace it with a new one that has the same amperage rating. The 2024 Chevrolet Blazer EV’s complex electrical systems will work smoothly because of this, giving drivers a reliable and efficient car experience.

Electrical System
High Voltage Devices and Wiring
Warning
Exposure to high voltage can cause shock, burns, and even death. The high-voltage components in the vehicle can only be serviced by technicians with special training.
High-voltage components are identified by labels. Do not remove, open, take apart, or modify these components. High voltage cable or wiring has orange covering or labels. Do not probe, tamper with, cut, or modify high-voltage cables or wiring.
Electrical System Overload
The vehicle has fuses and circuit breakers to protect against an electrical system overload. When the current electrical load is too heavy, the circuit breaker opens and closes, protecting the circuit until the current load returns to normal or the problem is fixed. This greatly reduces the chance of circuit overload and fire caused by electrical problems.
Fuses and circuit breakers protect power devices in the vehicle.
If there is a problem on the road and a fuse needs to be replaced, the same amperage fuse can be borrowed. Choose some feature of the vehicle that is not needed to use and replace it as soon as possible.
To check a fuse, look at the band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a fuse of identical size and rating.
Replacing a Blown Fuse
- Turn off the vehicle.
- Locate the fuse puller in the engine compartment fuse block.
- Use the fuse puller to remove the fuse from the top or side, as shown above.
- If the fuse must be replaced immediately, borrow a replacement fuse with the same amperage from the fuse block. Choose a vehicle feature that is not needed to safely operate the vehicle. Repeat Steps 2-3.
- Insert the replacement fuse into the empty slot of the blown fuse.
At the next opportunity, see your dealer to replace the blown fuse.
Headlamp Wiring
An electrical overload may cause the lamps to go on and off, or in some cases to remain off. Have the headlamp wiring checked right away if the lamps go on and off or remain off?
Windshield Wipers
If the wiper motor overheats due to heavy snow or ice, the windshield wipers will stop. The wiper function is available immediately after the wiper switch is set to off, and back to on. To protect the wiper motor from overheating, the wipers may slow down when the windshield is dry for a long period. If a period of dry operation, or little moisture, exceeds 10 minutes, the wipers may switch to intermittent operation, and remain there. When moisture is again detected on the windshield, wiper operation will return to the operator-selected speed.
Although the circuit is protected from electrical overload, overload due to heavy snow or ice may cause wiper linkage damage. Always clear ice and heavy snow from the windshield before using the windshield wipers.
If the overload is caused by an electrical problem and not snow or ice, be sure to get it fixed.
Fuses and Circuit Breakers
The wiring circuits in the vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of damage caused by electrical problems.
Danger
Fuses and circuit breakers are marked with their ampere rating. Do not exceed the specified amperage rating when replacing fuses and circuit breakers. The use of an oversized fuse or circuit breaker can result in a vehicle fire. You and others could be seriously injured or killed.
Warning
Installation or use of fuses that do not meet GM’s original fuse specifications is dangerous. The fuses could fail, and result in a fire. You or others could be injured or killed, and the vehicle could be damaged.

Underhood Compartment Fuse Block
To Access:
- Open the hood. See Hood.
- The underhood compartment fuse block is below the underhood access covers. To remove, see Underhood Access Covers.
- To open the fuse block cover, press the clips at the side and back and pull the cover-up.
Caution
Spilling liquid on any electrical component of the vehicle may damage it. Always keep the covers on any electrical component.
A fuse puller is in the underhood compartment fuse block.

FAQs
The 2024 Chevrolet Blazer EV typically has one main fuse box.
The fuse box is usually located in the engine compartment or near the driver’s side dashboard.
The Blazer EV may use a variety of fuse sizes, so it’s important to check the owner’s manual for specific details.
Look for a fuse with a broken filament or a discoloration. The owner’s manual will have a fuse diagram to help identify each fuse’s purpose.
A pair of needle-nose pliers or a fuse puller is typically sufficient to remove and replace fuses.
It’s essential to use a fuse with the same amperage rating as the one you are replacing to avoid electrical issues.
Open the hood, and there should be a labeled fuse box cover. Lift the cover to access the fuses.
Some models may come with spare fuses stored in the fuse box.
Fuse replacement is a relatively simple task. However, if you are unsure or uncomfortable, it’s advisable to consult a professional.
Overloading the circuit, a short circuit, or a faulty electrical component can cause fuses to blow.
The charging system may have a dedicated fuse.
Yes, a blown fuse can disrupt power to various electrical systems, affecting multiple components.
Regularly inspect fuses and replace any that are blown. There’s no fixed interval, but it’s good practice during routine maintenance.
Ensure the vehicle is turned off, and consult the owner’s manual for safety instructions. Wear gloves and safety glasses if needed.
While aftermarket fuses are available, it’s recommended to use OEM (original equipment manufacturer) fuses to maintain compatibility and safety.
