In this article, you will find information about the fuses of the Buick Enclave (models 2018, 2019, 2020, and 2021), including 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 Buick Enclave
The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links. This greatly reduces the chance of damage caused by electrical problems.
To check a fuse, look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a new one of the identical size and rating. Fuses of the same amperage can be temporarily borrowed from another fuse location, if a fuse goes out. Replace the fuse as soon as possible.
Caution!
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.
Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.
Location of Fuse Boxes
Engine Compartment Fuse Block: The underhood fuse block is in the engine compartment, on the driver side of the vehicle. To remove the fuse block cover, press the clips on the cover and lift it straight up.
Do not pull the engine compartment fuse block lever, since it is intended only for service purposes. If pulled, vehicle malfunction may occur.
Instrument Panel Fuse Block: The instrument panel fuse block is inside the center console on the passenger side of the vehicle. Remove the fuse access door by pulling on the left side of the access door.
Rear Compartment Fuse Block: The rear compartment fuse block is behind a trim panel on the driver side of the rear storage compartment. The trim panel is removed by prying along the top edge of the trim panel at two notched locations.
