1997 GMC SIERRA fuses

nrn Signal and Lane Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a
tum, move the lever all the way up or down.
When the
tum is finished, the lever will return automatically.
CII
An arrow on the instrument
panel will flash in
the
direction of the turn or lane
change.
To signal a lane change, just raise or lower the lever
until the arrow starts to flash.
Hold it there until you
complete your lane change. The lever will return by
itself when you release it. If you
move the lever all the way up or down, and
the
arrow flashes at twice the normal rate, a signal bulb
may be burned out and other drivers may not see your
turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If
the arrows don’t go on at all when you
signal a turn, check for burned-out bulbs and a blown
fuse (see “Fuses and Circuit Breakers” in the Index).
Headlamp High/Low Beam Changer
To change the headlamps from low to high beam or high
to low beam, pull the multifunction lever all the way
towards you. Then release it.
When the high beams are
on, this light on the
instrument panel also
will be on.

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. 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.
You may have spare fuses located behind the fuse block
access door. These can be used to replace a bad fuse.
However, make sure
it is of the correct amperage.

extractor
is mounted to the interior fuse block. 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.
