In this article, you will find information about the fuses of the Buick Regal (models 2011, 2012, and 2013), 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 Regal
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.
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!
- Data on the replacement fuse must match the data on the defective fuse.
- Before replacing a fuse, turn every vehicle electrical switch off.
- 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:
To remove the fuse block cover, press the three retaining clips on the cover and lift it straight up.
Instrument Panel Fuse Block:
The instrument panel fuse block is located in the instrument panel, on the driver side of the vehicle. To access the fuses, open the storage compartment. Press in on the sides of the compartment to release it from the instrument panel. Pull the door toward you to release it from the hinge.
