1998 CHEVROLET CORVETTE air condition

Downloaded from www.Manualslib.com manuals search engine a
+' LOWER: This setting directs most of the air
through the lower ducts to the floor area of the vehicle with some of the air also directed toward the windshield
and side window vents.
+# DEFOG: This setting divides the air between the
windshield and lower outlets with a small amount directed toward the side window vents. This is useful
when fog appears on the windshield or side glass due to
rain or snowy conditions.
DEFROST Use this setting to quickly remove fog
or frost from the windshield. This setting directs most of
the airflow to the windshield with
a small amount
directed toward the lower and side window outlets.
Mode Buttons
These buttons control the air intake, the air conditioning and the rear window defogger operation.
FRESH AIR: Press this button and it will bring
outside air into your vehicle. The light on the button will
come on when operating. Use this setting while trying to
defrost or defog windows to help clear moisture.
RECIRCULATE: Press this button to limit the
amount of fresh air entering your vehicle by
recirculating most of the
air inside your vehicle. The
light on the button will come on when operating. This
setting is helpful when you are trying to cool the air
quickly or to limit odors entering your vehicle.
RECIRCULATE cannot be used while in the DEFROST
or
DEFOG modes.
e A/C: This button turns the air conditioning
compressor
off or on under most conditions. The light
on the A/C button comes on when the compressor is
operating. The air conditioning does not operate at
temperatures below approximately
35 OF to 40°F (2" C
to 4°C). The air conditioning cools and dehumidifies the
air coming into the vehicle. The air conditioning cannot
be turned
off in DEFROST as it helps to remove
moisture from the vehicle. It also helps to keep the
windows clear.
The air conditioning may be forced
off at high engine
speeds
or high engine oil or coolant temperatures.

Downloaded from www.Manualslib.com manuals search engine Automatic Electronic Dual Climate Control System
(If Equipped)
Your vehicle may be equipped with a Dual Zone
Electronic Climate Control System. This system can
automatically adjust and control temperature output, fan
speed, air delivery mode, air conditioning operation and
air intake. You can use the AUTO (automatic) setting or
override the automatic operation with manual control
settings. The control settings will be remembered each
time you turn the ignition
off and restart in the same
settings. You can use the Memory option to store and
recall your settings. (See “Memory” in the Index.)
Digital Display
The digital display shows readings in Fahrenheit or Celsius
by pressing the EM button (EnglisWMetric) on the Driver
Information Center @IC). When you
start the vehicle, the
display will show the current fan speed, air delivery mode
and the driver-set temperature for approximately five
seconds and then show the outside temperature.
When the system is fully in the automatic mode, the
word AUTO will also appear on the display. If you have
selected a manual fan speed, then the fan symbol will
appear on the display.
If a manual air delivery mode has
been selected, the delivery mode symbol will appear on
the display.
Driver Set Temperature Knob
The DRIVER knob changes the temperature on the
driver’s and passenger’s side of the vehicle. Turn the
knob to the right to increase the temperature and to the
left to decrease the temperature. Whenever you turn this
knob, the temperature will be displayed for
approximately five seconds along with the current fan
speed and air delivery mode.
3-4

Downloaded from www.Manualslib.com manuals search engine When adjusting the temperature, start with a driver-set
temperature of
73°F (23 "C) until you determine your
comfort zone. If you choose
60°F (16"C), the system
will remain at maximum cooling and will not
automatically adjust fan speed or air delivery. If you
choose
90°F (32"C), the system will remain at
maximum heating and will not automatically adjust fan
speed or air delivery. Choosing either maximum setting
will not cause the system to heat or cool any faster.
Turning the knob past either maximum setting has no
effect on the operation of the system.
Passenger Temperature Offset
The PASSENGER knob changes the temperature on the
passenger's side of the vehicle. When the knob is in the
12 o'clock position, the passenger's temperature is the
same as the driver's. Turn the knob to the right for
warmer air
on the passenger's side, to the left for cooler
air. If the driver-set temperature is set at
60°F (1 6 " C) or
90 OF (32 " C), turning the passenger knob has no effect
because the system is locked at a maximum setting.
Automatic Operation
Press the AUTO button to place the entire system in the
automatic mode. After a five second display of the current settings, only the word
AUTO and the outside
temperature will be shown on the digital display. The
system will operate to achieve your comfort set
temperature as quickly as possible. If you have set the
driver temperature at
60°F (16°C) or 90°F (32"C), the
system will not operate automatically until a different
temperature is selected. The AUTO control system
works best with the windows up and the removable roof
installed or the convertible top up.
A Typical Cold Weather Example:
Your vehicle has been parked outside overnight in cold
weather (below
32 OF/ 0 " C) and you have set the driver
temperature at
73°F (23°C) and have selected the AUTO
mode. The system will automatically adjust the
temperature output to maximum heating. The fan will start
at a low speed. This is to avoid blowing cold
air into the
vehicle. The length of the delay depends on the amount of
time since the engine was last started, the outside
temperature and the engine coolant temperature. As the
coolant warms up, the fan speed will gradually increase.
Air will flow to the floor with some air to the windshield
to prevent fogging under most normal conditions.
3-5

Downloaded from www.Manualslib.com manuals search engine As the interior of the vehicle warms up to your comfort
set temperature, the fan speed will decrease and the
temperature output may become cooler.
If the interior
temperature continues to warm up due to heating from
the sun or outside temperature increases, the system
may switch to other air delivery modes (typically
DEFOG or BI-LEVEL).
A ljpical Hot Weather Example:
Your vehicle has been parked outside all day in hot
weather (above
7OoF/ 21 O C) and you have set the driver
temperature at
73 OF (23 "C) and have selected the
AUTO mode. The system will automatically adjust the
temperature output to maximum cooling. The blower
will start at a low speed momentarily to push the hot air
to the floor of the vehicle and then go to a higher blower
speed with cold airflow out of the instrument panel
outlets.
A small amount of airflow will continue through
the lower ducts to cool the
floor area.
The air intake may start in the recirculated mode for
maximum cooling performance.
As the interior of the
vehicle cools down to your comfort set temperature, the
fan speed will decrease and the temperature output may
become warmer. The air intake may shift from
recirculation to fresh air mode.
If the interior continues to
cool due to a decrease,,,in the amount of heat the
vehicle is absorbing from the sun or a decrease
in the
outside temperature, the system could switch to other air
delivery modes (typically BI-LEVEL or DEFOG).
Manual Settings
With the Dual Zone Electronic Climate Control, there
are several manual settings you can use to control the
system and override the
AUTO operation. You can
program the fan speed,
air delivery mode, air intake
mode and control the air conditioning operation using
these settings. The system will still determine the
temperature output level based on the driver-set
temperature and the passenger temperature offset.
% FAN SPEED: Press the button with the fan switch
on it to manually lock
in the current fan speed and to
stop the automatic fan speed control. Pressing the
arrows will delete
AUTO from the digital display. The
fan graphics with the fan speed bars will be shown.
To
increase the fan speed so that more air flows into the
vehicle, press the
UP arrow on the fan switch. To
decrease the fan speed and airflow, press the DOWN
arrow. The
AUTO button must be pressed to return to
the automatic fan control.

Downloaded from www.Manualslib.com manuals search engine MODE: Press the MODE button to manually lock in the
current air delivery setting and to stop the automatic

Downloaded from www.Manualslib.com manuals search engine FRESH AIR: Press this button to provide fresh
air from the outside. The light on this air intake button
will come on to show when it is operating. When in the
AUTO mode, the system automatically selects FRESH
AIR instead of RECIRCULATE, as required, to control
the temperature in the vehicle. By pressing FRESH
AIR, the system
will lock into the fresh air mode. Any
adjustment to the air intake must then be made
manually.
FRESH AIR should be used when trying to
defrost or defog windows to help reduce moisture inside
the vehicle.
RECIRCULATE: Press this button to limit the
amount
of fresh air entering the vehicle. The light on
this air intake button will come on to show when it is
operating. RECIRCULATE is helpful when you are
trying to cool the air quickly or trying to limit odors and
dust from entering the vehicle. When in the AUTO
mode, the system automatically selects RECIRCULATE
to cool the vehicle’s temperature. By pressing this
button, the system will lock into the recirculated air
mode. Any adjustment to the air intake must then be
made manually. The recirculated air mode is not allowed
in the front defrost or defog modes as fresh air helps
reduce moisture inside the vehicle.
FRONT: Press the FRONT defrost button to
quickly remove fog or frost from the windshield. This
setting directs most of the airflow to the windshield and
a small amount toward the lower and side window
outlets. The light on the button will come
on and the
digital display will show the defrost mode symbol and
fan speed when the front defrost mode is being used.
Pressing FRONT defrost again will return the system to
the last operating mode.
If the system is
in FRONT defrost when you shut the
engine
off, it will restart in FRONT defrost unless the
engine is off for longer than
40 minutes. If the engine is
off longer than 40 minutes, the system will restart in the
operating mode you had set prior to FRONT defrost.
The air conditioning cools and dehumidifies air coming
into the vehicle. It also operates in defrost to help
remove moisture from the vehicle. The air conditioning
does not operate at temperatures below approximately 35°F to
40°F (2°C to 4°C). If the system is operating in
the AUTO mode, turning the air conditioning
off will
delete AUTO from the digital display and show current
mode and fan settings. The AUTO button must be
pressed to return to the automatic mode operation.

Downloaded from www.Manualslib.com manuals search engine Air Conditioning Heating
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. Then keep your
windows closed in order to allow the air conditioning to
work best. Maximum cooling will occur when the
RECIRCULATE setting is operating, airflow direction is
in the upper mode, and the temperature control knob (on
a manual climate control system) is turned all the way to
the blue area. These settings will be selected by the
Automatic Electronic Dual Climate Control System if
operating in AUTO when maximum cooling is required.
When the air conditioning 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 maintaining the
desired cooling level.
The
air conditioning removes moisture from the air, so you
may notice water dripping fi-om under your vehicle when
it is idling or after it has been turned
off. This is normal. The
heater works best
if you keep your windows closed.
Maximum heating will occur when airflow direction is
in the lower mode and the temperature control knob (on
a manual climate control system) is all the way
in the
red area. These settings will be selected by the
Automatic Electronic Dual Climate Control System if
operating in AUTO when maximum heating is required.
The BI-LEVEL 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. The
BI-LEVEL setting will direct cooler airflow to
your upper
body and warmer
air to the floor area.
If you have the optional engine coolant heater and use it
during cold weather
0°F (- 18 “C) or lower, your heating
system will provide heat more quickly because the
coolant is already warmed. See “Engine Coolant Heater”
in the Index.
