1998 CHEVROLET VENTURE air condition

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows
a deployed air bag. The system
checks the air bag’s electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the air bag sensors, the air
bag module, the wiring and the diagnostic module. For
more information on
the air bag system, see “Air Bag”
in the Index.
This light will come on
when you start your engine,
and
it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for
a few
seconds when you turn the ignition key to
RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you
if there is a problem.
Charging System Indicator Light
1+1
The charging system light
will come on when you turn
on the ignition as a check to
show you it is working. It
will remain on as long as
the engine is not running.
It should go out once the engine is running. If
it stays
on, or comes on while you are driving, you may have a
problem with the charging system. It could indicate that
you have problems with a generator
drive belt, or
another electrical problem. Have
it checked right away.
Driving while this light
is on could drain your battery.
If you must drive a short distance with the light
on, be
certain to turn off all your accessories, such as the radio
and air conditioner.
Brake System Warning Light
When the ignition is on, the brake system warning light
will come on when you set your parking brake. The light
will stay on if your parking brake doesn’t release fully.
If it stays on after your parking brake is fully released, it
means you have a brake problem.

Malfunction Indicator Lamp (Service Engine Soon
Light)
SERVICE
ENGINE
SOON CHECK
United States Canadian
Your
vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
This system is called OBD
I1 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The SERVICE ENGINE SOON light
comes on and a chime will sound to indicate that there is
a problem and service is required. Malfunctions often
will be indicated by the system before any problem is
apparent. This may prevent more serious damage to
your vehicle. This system
is also designed to assist your
service technician in correctly diagnosing any
malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running.
If the light doesn't come on, have it repaired.
This light will also come on during a malfunction in
one of two ways:
Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.
0 Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.

If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
0 Avoiding hard accelerations.
0 Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light
Is On Steady” following.
If the light continues to flash, when it is safe to do
so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see “If the Light
Is On Steady” following. If the light
is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle? If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine
if the fuel
cap has been left off or improperly installed.
A loose or
missing
fuel cap will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed should
turn the light off.
Did you just drive through a deep puddle of water?
If
so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition.
Make sure to install the fuel cap properly. It
will take a few driving trips to turn the light off.
Have you recently changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index).
Poor fuel quality will cause your
engine not to run as efficiently as designed.
You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)

This section tells you how to make your air system work
for
you. Your comfort control system uses
ozone-friendly
R- 134a refrigerant.
With these systems,
you can control the heating,
cooling and ventilation
in your vehicle. Your vehicle
also has a flow-through ventilation system described
later
in this section. The

e RECIRC: Press this button (the light will glow)
to limit the amount
of fresh air entering your vehicle by
recirculating much of the air inside your vehicle. You
may use this setting to limit odors entering your vehicle.
Press the OUTSIDE AIR button (the light on the RECIRC button will go
off) to let outside air circulate
into the vehicle.
OUTSIDE AIR: Press this button (the light will
glow) to send outside air into your vehicle. Using this
setting while trying to defrost or defog the windows will
help clear the vents of moisture. Press the RECIRC
button (the light on the
OUTSIDE AIR button will go

DEFOG
or DEFROST setting is selected, the system
will automatically go to OUTSIDE AIR mode.
Air Conditioning
On very hot days, your vehicle will cool down more
quickly and economically if you open the windows long
enough to let hot, inside air escape. For all settings,
adjust the temperature control knob and fan speed
as desired.
To get maximum cooling or a quick cool-down on very
hot days, press the A/C and RECIRC buttons (the lights
will glow) and turn the temperature knob to the left
(toward the blue area). Adjust the mode
knob to direct
the air to the desired location. This setting should not be
used for long periods
of time because the air may
become too cold and dry. Push the A/C button again (the
light will go off) to turn
off the air conditioning.
When the air conditioner compressor is on, you may sometimes notice slight changes
in your vehicle’s engine
performance and power. This is normal. The system
is
designed to help fuel economy while it maintains the
desired cooling level.
The air conditioner removes moisture from the air,
so
you may sometimes notice water dripping from under
your vehicle’s engine compartment when it is idling or
after it has been turned off. This is normal.

Heating Defogging and Defrosting
Turn the temperature knob to the right (toward the red
area)
to warm the air.
In the LOWER mode, outside
air will be brought in and
sent through the floor outlets. The heater works best
if
you keep your windows closed while using it.
The BI-LEV setting is designed for use on sunny days
when the air is only moderately warm or cool. On days
like these, the sun may adequately warm your upper
body, but your lower body may not be warm enough.
For the best results,
turn the temperature control knob to
the middle position, and then adjust it for comfort.
If you have the optional engine coolant heater and use it
during cold weather,
0°F (- 18 O C) or lower, your heating
system will provide heat more quickly because the
engine coolant is already warmed. See “Engine Coolant
Heater” in the Index, To
rapidly defrost the windshield, turn the temperature
control knob all the way
to the right (to the red area) and
turn the mode knob
to DEFROST.
Adjust the fan to the highest speed.
To keep the windshield clear and bring in heated air
through the heater ducts, turn the mode knob
to
DEFOG.
When the temperature outside is above freezing, the air
conditioner compressor will
run in these settings to help
remove moisture from the air.
Your vehicle is equipped with side window defogger
vents located on the top of the instrument panel. For
additional side window defogging, turn the mode knob
to the
BI-LEVEL setting and adjust the fan to the
highest speed. Aim the side vents on the instrument
panel toward the side windows. For increased airflow to
the side vents, close the center vents.

Rear Climate Control (If Equipped)
If you have the optional rear climate control, the rear
seat passengers can control the temperature and the
amount of air directed
to the rear of the vehicle. The
amount
of air directed to the rear of the vehicle can also
be adjusted using the front control for the rear fan.
Set the main climate control mode knob to
LOWER,
DEFOG or DEFROST, when outside temperatures are
cold or moderate, to send air to the rear
of the vehicle
through the lower vents.
