Fixing a blown fuse: 2024 GMC Hummer EV Fuse Diagram
Presenting the 2024 GMC Hummer EV, a state-of-the-art electric car that blends cutting-edge technology and toughness. Just like with any high-tech car, maintenance and troubleshooting depend on knowing what parts are essential. The vehicle’s fuses and fuse box are important components that guard against potential damage to electrical components.
Fuses serve as safety measures, guarding against short circuits and overloads that could harm electrical components. To protect important components, every fuse is made to break the circuit when an excessive amount of current passes through it. The fuse box of the Hummer EV is filled with different fuses, each of which is responsible for a particular system in the car, like the climate control, power windows, or lights. An indication of a blown fuse could be a malfunctioning electrical component. Flickering lights, a sudden loss of power, or the affected system not working are indications of a blown fuse. Under such circumstances, it becomes imperative to examine and swap out the matching fuse. To ensure your safety and avoid electrical hazards, make sure the vehicle is off before attempting any fuse replacement.

Fuses and Fuse Box
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 the wires that provide the power to the devices in your 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 underhood 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 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.
Underhood Compartment Fuse Block
To Access:
- Open the hood. See Hood
- The Underhood Compartment Fuse Block is under a cover and side extensions/shields in the underhood compartment.
Complete a three-quarter turn on each of the three bolts on the left-side access cover.
- Press the clips at the side and back and pull the cover up to access the fuse block.
Caution
Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.
A fuse puller is in the underhood compartment fuse block.
The vehicle may not be equipped with all of the fuses and features shown.

FAQs
The engine compartment of the 2024 GMC Hummer EV is normally home to the fuse box.
The fuses in the Hummer EV act as safety measures, cutting the circuit in the event of an overload or short circuit, protecting the electrical components from harm.
Flickering lights, a sudden loss of power, or the failure of a single electrical component are all indications that a fuse has blown.
No, it’s imperative that a blown fuse be replaced with one that has the same amperage rating. Fuse errors can cause damage or electrical problems.
Changing out fuses is a reasonably easy task that you can perform on your own as long as you adhere to safety precautions. On the other hand, you should probably get professional help if you’re unsure.
Yes, extra fuses are typically included with the car.
It is true that a blown fuse can impact several electrical systems. In order to stop additional harm, it is imperative that the problem be resolved quickly.
The fuse box cover frequently has a fuse box diagram on it. If not, seek advice from a dealership or visit the website of the car manufacturer.
For safely removing and replacing fuses, a fuse puller or a pair of needle-nose pliers can be useful.
The answer is definitely yes. To shield fuses from the elements, make sure the fuse box is properly sealed.
It’s possible that the electric drivetrain has specialized fuses.
Check fuses on a regular basis if you experience electrical problems. Do a visual inspection as part of routine maintenance as well.
To guarantee compatibility and safety, OEM (original equipment manufacturer) fuses are advised.
For expert assistance, it’s advisable to speak with a certified technician or get in touch with your nearby GMC dealership if you run into problems.
