Greetings from the fuse system world of the 2024 Chevrolet Blazer! Gaining knowledge about your Blazer’s fuses and fuse box is similar to getting backstage access to its electrical workings. Fuses may appear to be small parts, but they have a big impact on protecting the electrical circuits in your car. The electrical infrastructure of your car is silently protected by the components found in the fuse box. As protectors, these fuses stop electrical overloads and make sure everything runs smoothly by cutting the circuit when needed. But sometimes even these sturdy guardians can give way under pressure, blowing fuses.
Prepare to solve the mysteries surrounding the fuses and fuse box of the 2024 Chevrolet Blazer. Equipped with this knowledge, you will be able to handle blown fuses with assurance, guaranteeing that the electrical systems in your Blazer continue to function flawlessly for miles to come.
Bulb Replacement
LED Lighting
This vehicle has several LED lamps. For replacement of any LED lighting assembly, contact your dealer.
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 cable 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.
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 the 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.
-
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 until the motor cools and will then restart.
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. 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.
See Accessories and Modifications and General Information .
To check or replace a blown fuse, see Electrical System Overload.
Engine Compartment Fuse Block
The underhood fuse block is in the engine compartment, on the driver side of the vehicle.
Caution
Do not pull the engine compartment fuse block lever, since it is intended only for service purposes. If pulled, vehicle malfunction may occur.
To remove the fuse block cover, press the clips on the cover and lift it straight up.
Caution
Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.
To remove fuses, use the fuse puller and pull straight out.
The vehicle may not be equipped with all of the fuses, relays, and features shown.

FAQs
Fuses guard electrical circuits by cutting the circuit in the event of an overload or short circuit, shielding the componentry from harm.
The Blazer’s fuse box can be found in a few different locations, most frequently in the engine compartment, under the dashboard, or in the trunk.
A blown fuse frequently has a discolored appearance or an internal filament that is clearly broken. Finding a blown fuse can also be aided by using a multimeter or fuse tester.
Most of the time, all you need to replace a fuse is your hands and a pair of pliers. For more information, always refer to your owner’s manual.
No, it isn’t advised. Using a higher rated fuse can harm the electrical components; fuses are rated according to their amp capacity to protect circuits.
As part of routine maintenance or whenever you see an electrical problem, check your fuses on a regular basis.
In order to properly diagnose the problem, it might be best to speak with a qualified technician if you are unable to locate a blown fuse.
Yes, depending on the model and trim, the Blazer may require a variety of fuses, including cartridge and blade fuses.
Indeed, several electrical components connected to the same circuit may be impacted by a blown fuse.
To prevent breaking the fuse or the fuse box, carefully grasp the fuse with your fingers and pull it out straight using a fuse puller tool.
Yes, extra fuses are frequently included with the car and are kept in the owner’s manual kit or fuse box.
Yes, changing a blown fuse at home is usually a simple do-it-yourself project. But if you’re not sure, check your owner’s manual or get expert assistance.
Yes, fuse box diagrams and other details are frequently available in owner’s manuals and online at forums for automobiles or the official Chevrolet website.
Electrical components that aren’t working properly, such as lights, power windows, or radios, are common indicators.
Fuse blowing repeatedly could be a sign of an underlying electrical problem. Get your car inspected by a qualified technician to identify and resolve the issue.
