In this article, you will find information about the fuses of the Buick Century (models 2000, 2001, 2002, 2003, 2004, and 2005), 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 Century
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.
Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating.
Caution!
- Data on the replacement fuse must match the data on the defective fuse.
- Before replacing a fuse, turn every vehicle electrical switch off.
Location of Fuse Boxes
Instrument Panel Fuse Block:
Some fuses are located in a fuse block on the passenger’s side of the instrument panel. Pull off the cover labeled FUSES to expose the fuse block.
Underhood Fuse Block:
Some fuses and relays are located in the underhood fuse block on the passenger’s side of the vehicle in the engine compartment.
