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.
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.
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.
