Headlamp Wiring; Windshield Wiper Fuses; Power Windows And Other Power Options; Fuses And Circuit Breakers - Buick 2005 Century Owner's Manual

Headlamp Wiring

The headlamp wiring is protected by a circuit breaker in
the underhood fuse block. An electrical overload will
cause the headlamps to go on and off, or in some cases
to remain off. If this happens, have the headlamp
system checked right away.

Windshield Wiper Fuses

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 instrument panel fuse block
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 the vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and in the fuse block 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
a bad fuse is replaced with a new one of the identical
size and rating.

Instrument Panel Fuse Block

Some fuses are located
in a fuse block on the
passenger's side of
the instrument panel.
Pull off the cover
labeled FUSES to
expose the fuse block.
