Electrical System
Add-on Electrical Equipment
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.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the underhood electrical center.
An electrical overload
will cause the lamps to go on and off, or in some cases
to remain
off. If this happens, have your headlamp
system checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker and a fuse.
If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools. If
the overload is caused by some electrical problem, have
it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load
is too heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is fixed.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links
in the wiring itself. This
greatly reduces the chance of fires 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.
[nstrument Panel Fuse Block
Some fuses are in a fuse
block on the passenger’s
side of the instrument panel.
Pull off the cover labeled
FUSES to expose the fuses.
