MODE Button

The MODE button is used to control the direction of airflow when the system is not in AUTO. The first press will display the current airflow direction. Repeated pressing will cycle through the following air flow directions show in the display.

UPPER: This setting directs air through the instrument panel outlets.

BI-LEV: This directs air two ways. Half of the air is directed through the instrument panel outlets. Most of the remaining air is directed through the floor ducts and a little to the defrost and side window vents.

DEFOG: This setting allows half of the air to go to the floor ducts and half to the defrost and side window vents. The air conditioning compressor will run automatically in this setting unless the outside temperature is below 4.5°C (40°F).

LOWER: This setting sends most of the air through the ducts near the floor. The rest comes out of the defrost and side window vents.

FRONT DEFROST BUTTON: This setting directs most of the air through the defrost an side window vents. Some of the air goes to the floor ducts. The air conditioning compressor will run automatically in this setting unless he outside temperature is below 4.5°C (40°F).

RECIRC BUTTON: This setting recirculates the air inside of your vehicle. This setting recirculates he air inside of your vehicle. This setting is not available in defog or defrost mode.

OUTSIDE AIR BUTTON: This setting brings in outside air.
In the automatic mode, the desired temperature is set by the driver/passenger.

A microprocessor uses the following information in order to provide the desired comfort level:
^ The temperature setting that the driver/passenger chooses
^ The coolant temperature
^ The vehicle speed
^ The two air temperature sensor inputs
- Outside (Ambient)
- Inside
^ The solar sensor input

The microprocessor also provides for system self-tests.
The self-tests result in diagnostic code displays.

Malfunctions in the following circuits are identified when the control is set to the diagnostic mode:
^ The inside temperature sensor circuit
^ The outside temperature sensor circuit
^ The temperature valve control circuit Diagnostic mode activation and fault code identification. Refer to Scan Tool Diagnostics. Testing and Inspection
