2024 Buick Envista Fuses and Fuse Box | How to replacing fuses
The fuses and fuse box of the 2024 Buick Envista are vital protectors of the vehicle’s electrical system, guaranteeing dependability and safety while driving. Typically positioned in the engine compartment or beneath the dashboard, the fuse box holds an assortment of fuses with varied amperage ratings. These fuses are essential for protecting the electrical systems of the car from overloads, short circuits, and other electrical problems. A fuse will blow in a circuit when it draws too much current, protecting the linked part from harm. The fuse box of the 2024 Buick Envista makes it easier to diagnose and fix electrical problems while maintaining the smooth operation of other car systems, which ultimately improves performance and safety for a worry-free 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 the 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.
- 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
To remove the fuse block cover, squeeze the clip and lift it up.
Caution
Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.
The vehicle may not be equipped with all of the fuses, relays, and features shown.
