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 an intern
a1 circl
ui
t
breaker. 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
an internal
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, be sure to have
it
fixed.
Power Windows and Other Power
Accessories
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 or
goes away.
