Checking and Replacing Fuses in Buick Terraza

The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers, and fusible thermal links.

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.

If you ever have a problem on the road and do not have a spare fuse, you can borrow one that has the same amperage or use one of the spare fuses in the underhood fuse block. Just pick some feature of your vehicle that you can get along without, like the radio or cigarette lighter, and use its fuse if it is the right amperage. Replace it as soon as you can.

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

There are two fuse blocks in your vehicle, the instrument panel fuse block and the underhood fuse block.

Instrument Panel Fuse Block:
The instrument panel fuse block is located at the right end of the instrument panel, on the passenger’s side of the vehicle. Open the front passegner’s door, and remove the cover, to access the fuse block.Buick Terraza (2005-2007): Passenger compartment fuse panel location
