2007 HUMMER H3 Fuses and circuit breakers

The system can only be activated using the
remote keyless entry transmitter, or by OnStar®.
SeeOnStar®System on page 129for additional
information. You should also remember that
you can start your vehicle with the correct key if
the alarm has been set off.
Here is how to avoid setting off the alarm by
accident:
If you do not want to arm the theft-deterrent
system, the vehicle should be locked with
the manual door lock lever, the power
door lock switch, or the key, after the doors
are closed.
If the content theft-deterrent system is armed,
unlock the doors by pressing the unlock
button on the remote keyless entry transmitter
or by OnStar
®. Unlocking a door any other
way will activate the alarm.
If you set off the alarm by accident, you can turn it
off by pressing unlock on the remote keyless
entry transmitter, starting the vehicle with
the correct key, or by having OnStar
®unlock the
doors. The alarm will not stop if you try to
unlock a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, activate the system
by locking the doors with the remote keyless
entry transmitter.
2. Unlock the door with the manual door lock
and open the door. This should set off the
pre-alarm. Wait 10 seconds for the full alarm
to activate.
3. To turn the alarm off, press the unlock button
on the remote keyless entry transmitter or
start the engine.
If the alarm does not sound when it should but the
lights ash, check to see if the horn works. The
horn fuse may be blown. To replace the fuse, see
Fuses and Circuit Breakers on page 417.
If the alarm does not sound or the front turn signal
lamps do not ash, see your dealer for service.

Turn and Lane-Change Signals
The turn signal has one upward (for right) and
one downward (for left) positions. These positions
allow you to signal a turn or a lane change.
To signal a turn, move the lever all the way up or
down. When the turn is nished, the lever will
automatically return to the off position.
To signal a lane change, raise or lower the lever
until the arrow starts to ash. Hold it there until
the change is completed. The lever will return by
itself when released.
An arrow on the
instrument panel
cluster will ash in
the direction of the
turn or lane change.
As you signal a turn or a lane change, if the
arrows ash more quickly than normal, a signal
bulb may be burned out and other drivers will
not see your vehicle’s turn signal.If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when
signaling a turn, check for a burned-out bulb or a
blown fuse. For bulb replacement, seeTaillamps,
Turn Signal, Stoplamps and Back-up Lamps
on page 363. For a blown fuse or circuit breaker,
seeFuses and Circuit Breakers on page 417
Turn Signal On Chime
If a turn signal is left on for more than 3/4 of a
mile (1.2 km), a chime will sound at each ash of
the turn signal and the message TURN SIGNAL
will also appear in the DIC. To turn the chime and
message off, move the turn signal lever to the
off position.
See “TURN SIGNAL” underDIC Warnings and
Messages on page 196DIC Warnings and
Messages for more information.

Windshield Wiper Fuses
The windshield wiper motor is protected by a
circuit breaker and a fuse. If the motor overheats
due to heavy snow or ice, the wiper will stop
until the motor cools. If the overload is caused by
some electrical problem, be sure to get it xed.
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 xed
or goes away.
Power and Heated Seat Circuit
Breakers
There is a circuit breaker located underneath the
driver’s side front seat that controls the power
and heated seat functions.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses
and circuit breakers. This greatly reduces
the chance of res 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 do
not 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.
