2023 GMC Yukon Fuse Box Diagram | How to Replace fuses
In the 2023 car world, the GMC Yukon is the ultimate in luxury and speed. Its electrical system is based on a complex network of fuses that are housed in a box called a fuse box. The 2023 GMC Yukon‘s fuse box is a hub for technology. It controls a symphony of electrical functions that power everything from high-tech safety features to entertainment systems. Positioned carefully inside the vehicle, this important part protects against electricity problems and makes sure everything works perfectly. As people take trips in their 2023 Yukon, the fuse box protects new ideas by combining cutting-edge technology with dependability in a way that doesn’t seem strange. This look into the Yukon’s fuses and fuse box shows how complicated things are under the hood and how these silent guardians help make the driving experience unmatched, where luxury meets efficiency on the open road.

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. 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 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 and General Information .
To check or replace a blown fuse, see Electrical System Overload
Engine Compartment Fuse Block
The engine compartment fuse block is in the engine compartment, on the driver 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
Usually found in the engine compartment, close to the battery, is the fuse box.
Check the fuse for a broken wire or an element that is clearly melted. A multimeter can also be used to verify continuity.
We don’t advise doing that. If a fuse blows, always replace it with one that has the same amp rating to avoid damaging the electrical system.
A multimeter for more in-depth diagnostics, a flashlight, and a fuse puller are basic tools.
Visually inspect fuses on a regular basis, and more often if you have electrical problems.
It’s possible that your car has both mini and blade-type fuses. Get acquainted with both kinds.
Depending on the function that is impacted. Before driving, critical systems like the brakes and lights should be fixed.
Given that it matches the designated slot and has the same amp rating, the answer is yes.
Don’t overload circuits, and take quick care of electrical problems to stop damage.
A professional mechanic should be consulted for a comprehensive inspection and diagnosis.
Fuse performance can be affected by extremely high or low temperatures. In these circumstances, routinely check fuses.Fuse performance can be affected by extremely high or low temperatures. In these circumstances, routinely check fuses.
Fuse failures can occur internally without obvious damage. For a more accurate measurement, use a multimeter.
Just grab the fuse with the puller and pull, gently rocking it back and forth to remove it.
To avoid potential problems, if in doubt, refer to your car’s manual or get help from a qualified mechanic.
