1996 GMC SIERRA fuse

Electrical System
Ac . .-On Electrical Equipment
NOTICE:
Don’t add anything electrical to your vehicle 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 vehicle, see “Servicing
Your Air Bag-Equipped Vehicle”
in the Index.
Headlamps
The headlamp wiring is protected by an internal circuit
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 wiring 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 and
not snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers 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.

Fu ~ ~ s 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. 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.
If you ever have a problem on the road and don’t have a
spare fuse,
you can borrow one that has the same
amperage.
Just pick some feature of your vehicle that
you can get along without -- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace
it as soon as you can.
Instrument Panel Fuse Block
The fuse block access door
is on the driver’s side edge
of the instrument panel. Pull
off the cover
to access the
fuse block.
You can remove fuses with a fuse extractor. The fuse
extractor
is mounted to the fuse block access door. To
remove fuses if you don’t have a fuse extractor, hold the
end of the fuse between your thumb and index finger
and
pull straight out.
