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 end cap, 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. 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
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 on the vehicle may damage it. Always keep the covers on any electrical component.

How to Replace GMC Sierra 1500 Fuses
Replacing fuses in a GMC Sierra 1500 is a straightforward process. Here’s a detailed guide along with some tips:
-
Locate the Fuse Box: The fuse box in the GMC Sierra 1500 is typically located under the dashboard on the driver’s side or under the hood near the battery. Look for a rectangular box with a removable cover.
-
Turn Off the Ignition: Before you start, ensure that the ignition is turned off to prevent electrical accidents.
-
Identify the Blown Fuse: Use the fuse diagram located on the fuse box cover or inside the fuse box panel to identify the fuse corresponding to the malfunctioning component. Look for any fuse with a broken wire inside it or a visibly melted appearance.
-
Remove the Blown Fuse: Using a fuse puller tool or a pair of needle-nose pliers, grasp the blown fuse firmly and pull it straight out of its socket. Be gentle to avoid damaging the fuse or the fuse box.
-
Select a Replacement Fuse: Choose a new fuse with the same amperage rating as the blown one. Using a fuse with a different rating may result in electrical problems or damage to the vehicle’s systems.
-
Insert the Replacement Fuse: Align the new fuse with the socket and push it in firmly until it’s fully seated. Ensure it’s inserted straight to prevent bending the terminals.
-
Check for Proper Installation: After replacing the fuse, visually inspect it to ensure it’s securely in place. Wiggle it gently to confirm it’s not loose.
-
Test the Component: Turn the ignition back on and test the component associated with the replaced fuse to confirm it’s functioning properly.
Tips:
- Always carry spare fuses of various amperages in your vehicle’s glove compartment for emergencies.
- If you’re unsure about which fuse to replace or encounter any difficulties, it’s best to seek assistance from a qualified mechanic.
- Regularly inspect your vehicle’s fuses during routine maintenance to identify any potential issues early on.
- Keep the fuse box area clean and free of debris to ensure easy access when replacing fuses.
