Corvette V8-5.7L VIN G (1997)
Ambient Temperature Sensor / Switch HVAC: Description and Operation
The outside air temperature sensor is located in the front grill area under the front bumper of the vehicle. The HVAC control head uses this sensor to
receive information on ambient air temperature. With this information, the HVAC control head will give the driver the outside air temperature on the
digital display. If the outside temperature increases, the displayed temperature will not change until:
-
The vehicle's speed is above 32 km/h (20 mph) for approximately one and a half minutes.
-
The vehicle's speed is above 72 km/h (45 mph) for approximately on minute.
These delays help prevent false readings. If the displayed temperature goes down, the outside temperature display is updated immediately. If the vehicle
has been turned off for more than three hours, the current outside temperature will be shown when the vehicle is started. If it has been turned off for less
than three hours, the temperature will be recalled from the previous vehicle operation.
