In this article, you will find information about the fuses of the GMC Yukon/Yukon XL (GMT 1YG) (models 2021, 2022, 2023, and 2024) diagrams of the fuse boxes, a list of fuses and relays, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in Yukon/Yukon XL
The wiring circuits in the vehicle are protected from short circuits by fuses. This greatly reduces the chance of fires caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse.
Caution!
Be sure you replace a bad fuse with a new one of the identical size and rating.
Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.
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.
Location of Fuse Boxes
Engine Compartment Fuse Block: The engine compartment fuse block is in the engine compartment, on the driver side of the vehicle.
Instrument Panel Fuse Block: The right instrument panel fuse block access door is on the passenger side edge of the instrument panel. Pull off the cover to access the fuse block. There are relays on the back of the fuse block. To access, press the tabs and remove the fuse block.
Rear Compartment Fuse Block: The rear compartment fuse block is behind the access panel on the left side of the compartment. Pull the panel out by grabbing the finger access slot at the rear edge.
The windshield wiper motor is protected by an internal circuit breaker and a fuse. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools.
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.
