2003 CHEVROLET VENTURE fuses

If the accessory in¯ator system does not turn on or the
light does not come on, the fuse may be blown or
installed incorrectly. See
Fuses and Circuit Breakers on
page 5-96or see your dealer for service.
Your accessory in¯ator will automatically shut off after
about 10 minutes. The light in the switch will blink. After
about one minute you can use the system again.
Press the switch and the indicator light will come on.
Notice:If you run the accessory in¯ator longer than
30 minutes at a time, you could damage the
in¯ator. The repairs would not be covered by your
warranty. Run the in¯ator for short periods of
time only.After running the accessory in¯ator for 30 minutes, wait
at least 10 minutes before restarting the accessory
in¯ator.
To turn off the in¯ator, do the following:
1. Press the switch and detach the hose, ®rst from the
in¯ated object, then from the outlet.
2. Put the protective cap back on.
3. Place the in¯ator kit tools in the pouch, and store in
the glove box.
To put the cap back on, line up the tabs at the back of
the cover and put it in place. Push down the tab to
secure the cap.

Electrical System
Add-On Electrical Equipment
Notice:Don't add anything electrical to your vehicle
unless you check with your dealer ®rst. 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 on page 1-102.
Headlamp Wiring
The headlamp wiring is protected by an internal circuit
breaker in the instrument panel fuse panel. 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 Wiper Fuses
The windshield wiper motor is protected by an internal
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, be sure to get it ®xed.
Power Windows and Other Power
Options
Circuit breakers in the instrument panel fuse panel
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.
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.
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 or use one of the spare fuses in the
underhood fuse block. 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 right
amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle, the instrument
panel fuse block and the underhood fuse block.

Underhood Fuse Block
This fuse block is located
in the engine compartment,
in front of the windshield
washer ¯uid reservoir. See
Engine Compartment
Overview on page 5-12for
more information on
location.
The fuses marked spare are available if a replacement
fuse is needed.
To remove the cover, turn the knob counterclockwise
and lift up.
When ®nished, to put the cover back on, turn the knob
clockwise to tighten it. Make sure that the remote
positive (+) terminal cover is on correctly.
