NOTICE:
Don’t add anything electrical to your Buick unless
you check with your dealer first. Some electrical equipment
can damage your vehicle and the
damage wouldn’t be covered by your warranty. Some add-on electrical equipment can keep other
components
from working as they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your Buick, see “Servicing
Your
Air Bag-Equipped Buick” in the Index.

Fuses and Circuit Breakers
The wiring circuits in your 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.
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.
There are three fuse blocks in your vehicle: the
Instrument Panel Fuse Block located under the
instrument panel, the Underhood Fuse Block located on
the passenger’s side engine compartment, and the Rear
Fuse Block located under the rear seat.
Instrument Panel Fuse Block
The right side fuse panel is located under the
instrument panel.
Remove the hush panel to reveal the fuses.
To remove
the panel, remove the three screws located along the
rear edge of the panel. Place the wide end
of the fuse
puller over the plastic end
of the fuse. Squeeze the ends
over the fuse and pull it out.
>pare fuses are located
in the empty slots shown on the
following chart. When finished, replace
the hush panel. Replace lamps,
connectors, and HVAC duct temperature sensors if they
were removed.
