CJ2

With this system, you set a temperature. You can then either let the system adjust airflow and force to maintain the temperature, or you can manually adjust the flow and force. The system works best if you keep your windows closed while using it.

Driver Temperature Knob

The left (DRIVER) knobs sets the temperature for the entire system when the right (PASS) knob is in the center or neutral position. Turn the DRIVER knob toward red to the right to raise the temperature. Turn it toward blue to the left to lower the temperature. The display will show your selection for a few seconds, then the outside temperature will show. If you push the knob the set temperature will again be displayed for a few seconds, the outside temperature will show.

Passenger Temperature Knob

The right (Pass) knob adjusts the air temperature on the passenger's side so it is warmer or cooler than the temperature set by the driver.

Turn the PASS knob toward red to the right to raise the temperature. Turn it toward blue to the left to lower the temperature. The passenger temperature will not be shown in the display.

Auto Button

For the most efficient operation you should press the AUTO button and set the system temperature. The system will select the best fan speed and airflow settings. The air conditioning compressor will run if the outside temperature is above 40°F (4.5°C). You may notice a delay of three to four minutes before the fan comes on.

Off Button

Push the OFF button to turn the system off. The display will show OFF and outside temperature. The system will continue to automatically control air temperature to the last set temperature.

Manual Control

To manually control the heating, cooling and ventilation in the vehicle, set the system to the temperature and fan speed you want. Next, push the desired airflow direction push button. The system will try to maintain the temperature you set using the mode you select. The following suggestions will help the system run more efficiently in manual mode.

Fan Button

The button below the display is used to manually select the force of air you want. The display will show the fan speed. Fan control is no longer automatic, but the system remains in auto temperature control.

If the airflow seems very low when the fan knob is turned to the highest setting regardless of the mode setting, your passenger compartment air filter (if equipped) may need to be replaced.

A/C Button

Press the A/C button to turn the compressor on/off. AUTO will be extinguished, but system will maintain auto air delivery and auto blower.

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 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:
