2024 Chevrolet Suburban Fuses and Fuse Box | How to replace fuses
The electrical system in the 2024 Chevrolet Suburban is very advanced and makes sure that all of its parts work perfectly. The fuse box is the most important part of this system. It protects the technology in the car by stopping electrical overload. The fuse box is placed smartly; it can usually be reached from under the dashboard or in the engine area. It holds a group of fuses, each of which is responsible for protecting a certain circuit. As a safety measure, these fuses break the electrical circuit when it’s exposed to too much current. This keeps connected gadgets from getting damaged. If something goes wrong or there is a power surge, you need to repair the faulty fuse right away. In the 2024 Chevrolet Suburban, replacing the fuses is a simple task. You should first look in the owner’s guidebook to find the exact location of the fuse that controls the broken part. Once you find it, carefully remove the broken fuse using the fuse puller that came with the package or a pair of needle-nose pliers. After that, put in a new fuse with the same amperage number and make sure it fits securely. This simple but necessary repair task makes sure that the car’s electrical systems keep working, so Suburban owners can enjoy a smooth and reliable driving experience.

Electrical System
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 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. 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.
See Accessories and Modifications 0 323 and General Information 0 323. To check or replace a blown fuse, see Electrical System Overload 0 347.
Engine Compartment Fuse Block
If the vehicle has a diesel engine, see the Duramax diesel supplement. The engine compartment fuse block is in the engine compartment, on the passenger side of the vehicle.
Lift the cover to access the fuse block.
Caution
Spilling liquid on any electrical component of the vehicle may damage it. Always keep the covers on any electrical component.

FAQs
The fuse box in the 2024 Chevrolet Suburban is typically located in the engine compartment or on the driver’s side of the dashboard.
There may be more than one fuse box in the 2024 Chevrolet Suburban. Common locations include the engine compartment and interior near the driver or passenger seat.
Fuses protect electrical circuits in a vehicle by breaking the circuit if there’s an overload or short circuit, preventing damage to the electrical components.
Look for a melted or broken metal strip inside the fuse. If it’s damaged, the fuse is likely blown. Also, the transparent plastic cover may show signs of discoloration.
Typically, you’ll only need a pair of needle-nose pliers or a fuse puller to safely remove and replace a fuse.
Yes, there are often spare fuses in the fuse box. Check the diagram on the fuse box cover to identify the spares.
No, it’s not recommended. Always use the correct amp rating for the fuse to avoid damaging the electrical system.
The fuse box covers a list of fuses and their corresponding amp ratings.
It’s generally safer to replace fuses with the ignition turned off to avoid electrical shock or damage.
There may be an underlying issue causing the fuse to blow. Consult a professional mechanic to diagnose and fix the problem.
Check the owner’s manual for specific instructions. Usually, you’ll need to open the driver’s side door and locate a panel on the side of the dashboard.
Yes, replacing fuses is a simple DIY task. Follow the instructions in the owner’s manual for your Suburban.
Yes, different electrical components may have dedicated fuses. See the fuse box diagram for details.
While there isn’t a strict order, it’s good practice to replace one fuse at a time and check if the issue is resolved before moving on.
It’s not recommended. Fuses and circuit breakers serve different purposes, and using a circuit breaker in place of a fuse may not provide proper protection for the electrical system. Stick to the recommended fuse type and rating.
