2007 BUICK TERRAZA fuse

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.
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.
Your vehicle may not have all of the fuses listed.
