Corvette V8-5.7L VIN G (1997)
Select the off mode to turn off the blower motor and the A/C compressor. The control head displays the SET TEMP information for 5 seconds, then
reverts to the OUTSIDE TEMP display.
While the vehicle is moving, some air is forced into the vehicle through the air intake. This air is delivered through the HVAC module and out of the
Heater and Defrost ducts.
When the A/C compressor is off, the air temperature can still be adjusted. The air can be warmed, but not cooled.
Auto
In the auto mode the control head turns on the system power. The system tries to obtain the last temperature setting and the system tries to maintain
that setting. The system changes the air delivery mode to automatic and the system illuminates the AUTO and AIR DELIVERY mode graphics.
The blower speed adjusts automatically as the system nears the temperature setting. The blower speed changes by pushing the blower speed button up
or down. The control head displays the SET TEMP information for 5 seconds. Then the control head reverts to the OUTSIDE TEMP display and
illuminates the air delivery mode graphics.
Mode
Press the MODE button to manually lock in the current air delivery setting and to stop the automatic mode control. Pressing the MODE button will
delete AUTO from the digital display and the MODE graphics will be shown.
When the mode button is pushed, the control head cycles through the manual air delivery modes in the following sequence:
1. UPPER
2. LOWER
3. DEFOG
4. BILEVEL
Recirc
Press this button to limit the amount of fresh air entering the vehicle. The light on the button will come on to show that the system is operating. Recirc
is helpful when you are trying to cool the air quickly or trying to limit odors and just from entering the vehicle. When the system is in the AUTO
mode, the system automatically selects Recirc 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 Recirc mode will not operate in the front defrost mode, this helps prevent
windshield and window fogging due to moisture in the vehicle.
The recirc mode function operates in the following air delivery modes:
-
UPPER
-
LOWER
-
DEFOG
-
BILEVEL
Upper
This setting directs most of the air through the instrument panel outlets and a very small amount to the lower outlets.
