Fuse box diagrams (layout, location, function, assignment) in the cabin and engine compartment of Buick Regal (2011, 2012, 2013, 2014, 2015, 2016, 2017).
Checking and Replacing Fuses
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.
Warning!
- Do not repair fuses and never replace a blown fuse with one that has a higher amp rating. This can cause damage to the electrical system and fire.
- Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.
