Your vehicle has several settings for clearing your
windows. The air conditioning compressor will run to
help remove moisture from the air.
Manual Cooling
The air conditioner works best if you keep your
windows closed. On very hot days, open the windows
just long enough for the hot air to escape.
Press the arrows on the TEMP ,SET switch to set a
comfortable temperature. Press RECRCULATE. After
cool-down, adjust the airflow to another setting. The
compressor works in all settings except VENT and
HEATER, and at all temperatures above freezing.
Press the arrows on the fan’ speed switch if you don’t
like the automatic setting. In AUTO FAN on hot days,
the fan speed will be low at first to help get rid of the
hot inside air.
When the air conditioner
is on, you may notice slight
changes in your vehicle’s engine speed and power. This
is normal because the system is designed to cycle the
compressor on and off to keep the desired temperature
and help fuel economy. To
defrost the windshield quickly, press the arrows on
the TEMP SET switch to set a comfortable temperature.
Press DEFROST and the fan will go to high speed. After
the windows
are clear, you can lower the speed using the
downward arrow or AUTO FAN.
With the automatic system, to warm passengers while
keeping the windshield clear, press the arrows on the TEMP SET switch to set a comfortable temperature.
Press HEATER and DEFROST at the same time and, if
you don’t,like the automatic setting, press the arrows on
the fan speed switch.
To defrost
the side windows quickly, press the arrows on
the
TEMP SET switch to set a comfortable temperature.
Then press DEFROST and, if you don’t like the automatic
setting, press the mows on the fan speed switch.

System Problems
If the light above an air control button flashes when you
turn on the ignition, your system may have an electrical
problem. The flashing will continue for one minute,
then stop.
The flashing light could also mean the refrigerant level
is too low in your system. The light will continue to
flash, even if refrigerant is added, until the system is
reset. Have your system checked and serviced if needed.
To reset your system:
1. Turn your ignition key to OFF or LOCK.
2. Remove the courtesy lamps and radio fuses from the
main fuse panel and wait one minute. See “Fuses and
Circuit Breakers” in the Index.
3. Put the fuses back in and start your vehicle.
The light shouldn’t come on and your system should be
working properly. If you still have
a problem, see
your dealer.

of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn’t be covered by your warranty.

louvered vents.
Your Corvette’s flow-through ventilation system
supplies outside air into the vehicle when it is moving.
