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 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 on the instrument panel end cap.
- Use the fuse puller to remove the fuse from the top or side, as shown above.
- If the fuse must be replaced immediately, spare fuses are also provided on the instrument panel endcap or 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.
Engine Compartment Fuse Block
The engine compartment fuse block is in the engine compartment, on the driver’s side of the vehicle.
Lift the cover 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.
Fuses Usage
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. A fuse puller is available on the right instrument panel end cap.
There are relays on the back of the fuse block. To access, press the tabs and remove the fuse block.
The vehicle may not be equipped with all of the fuses, relays, and features shown.
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 vehicle may not be equipped with all of the fuses, relays, and features shown.
How to Replace the Fuse of GMC Youkon XL
Replacing fuses in a GMC Yukon XL is a relatively straightforward process.
Here’s a step-by-step guide along with some tips:
- Locate the Fuse Box: The fuse box in a GMC Yukon XL is typically located in one of two places – either under the hood near the battery or inside the vehicle, usually on the driver’s side dashboard or under the steering column.
- Turn Off the Vehicle: Ensure the vehicle is turned off and the key is removed from the ignition to prevent any electrical mishaps.
- Remove the Fuse: Using the fuse puller tool located inside the fuse box or a pair of needle-nose pliers, gently grasp the blown fuse and pull it straight out. Be careful not to damage surrounding fuses or wiring.
- Inspect the Fuse: Examine the blown fuse to confirm it is indeed faulty. A blown fuse will typically have a broken wire inside or a visibly burnt appearance.
- Select the Replacement Fuse: Choose a replacement fuse with the same amperage rating as the one you removed. Using a fuse with a higher or lower rating can cause electrical issues or damage to the vehicle’s components.
- Install the Replacement Fuse: Insert the replacement fuse into the corresponding slot in the fuse box. Ensure it is seated securely and fully inserted.
- Test the Component: Once the replacement fuse is installed, test the component associated with the fuse to ensure it is functioning properly.
- Replace Fuse Box Cover: If you removed the fuse box cover, securely reattach it to the fuse box.
- Dispose of the Blown Fuse: Safely dispose of the blown fuse. It’s a good idea to keep spare fuses in your vehicle for future use.
Tips:
- Always use the correct amperage fuse for replacement to prevent electrical damage.
- Inspect the fuse box and wiring for any signs of corrosion or damage while replacing fuses.
- If a fuse blows repeatedly, it may indicate an underlying electrical issue that requires professional diagnosis.
- Keep a flashlight handy for better visibility when working in dimly lit areas.
- Double-check that all electrical accessories are turned off before replacing fuses to avoid electrical shocks or short circuits.
