1994 GMC SIERRA headlight bulb

A green 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 green arrow
starts to flash.
Hold it there until you complete your lane change. The lever
will return by itself when you release it.
As you signal a turn or a lane change, if the arrows don’t flash but just stay
on, a signal bulb may be burned out and other drivers won’t see your turn
signal.
If a bulb
is burned out, replace it to help avoid an accident. If the green
arrows don’t go on at all when
you signal a turn, check for burned-out bulbs
and a blown fuse
(see “Fuses” in the Index).
Headlight High-Low Beam
To change the
headlights
from low
beam to high or high
to low, pull the turn
signal lever
all the
way toward
you. Then
release
it.

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 in the
wiring itself. This greatly reduces the chance of fires caused by electrical
problems. See “Fuses and Circuit Breakers” in the Index for more
information.
Headlights
The headlight wiring is protected by a circuit breaker in the \
light switch. An
electrical overload will cause the lights to flicker on and of\
f, or in some
cases to remain
off. If this happens, have your headlight 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. Although the circuit is protected from electrical \
overload,
overload due to heavy snow, etc., may cause .wiper linkage damage. Always
clear ice and heavy snow from the the windshield before using \
the
windshield wipers.
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 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. This protects the circuit until the current \
load returns to
normal or the problem is fixed
.
