Climate Control System with A/C

Climate Control System with Air Conditioning

(Fan Control Switch): This switch sets the fan speed. Select the force of air you want by moving the switch. The fan control switch also controls the operation of the A/C Recirculate buttons. If you move the switch to OFF, the fan, A/C, and Recirculate functions will not operate.

Knob Controls

The left knob changes the temperature of the air coming through the system. The right knob allows you to select the mode and the path of air flow through the various outlets in the system. You can position the knob between settings to vary the sir flow from the different outlets.

(Vent): Turn the right knob to Vent setting. Air flow is directed through the instrument panel outlets. Set the left knob to the temperature desired.

(Bi-Level): Push the A/C button and set the control mode to Bi-Level. When the A/C button is pushed, an indicator light will light. This setting brings in the outside air, but directs it in two ways. The air is directed through the instrument panel outside air, but directs it in two ways. The air is directed through the instrument panel outlets and also directed through the floor outlets.

(Heater): Turn the right knob to the heater setting. This will send air through the heater outlets, rear floor outlets, and some through the windshield defroster outlets.

(Defrost/Heater): This setting directs air in two ways. The air is directed through the defroster and heater outlets. This setting should be used to keep glass fog free. The air conditioning compressor will run automatically in this mode when it is needed to kelp dry the air in the vehicle. NOTE: During extremely cold weather, 10°F (-12°C) or colder, your engine's coolant temperature will decrease quickly when idling with the heater fan on high speed and cool air may flow from the heater outlets. The fan control switch can be set at a slower speed position (fan speed I or II) to maintain the hottest air flow.

(Defrost/Defogging Windows): This setting directs the air through the windshield defroster outlets onto the windshield and past the front side windows. Use this setting if windows are fogged or icy. This setting will also help defog the front side windows. Set the mode knob to Defrost and set the temperature knob to full hot (fully clockwise). To quickly clear the windows, set the fan control switch to high.

Notice: Do not use anything sharp on the inside of the rear window. If you do, you could cut or damage the warming grid, and the repairs would not be covered by the vehicle warranty. Do not attach a temporary vehicle license, tape, a decal or anything similar to the defogger grid.

Air Conditioning and Recirculate Buttons

A/C: Air conditioning can be selected in any mode as long as the fan switch is on. When the button is pushed, the indicator light will come on. On very hot days, open the windows long enough to let hot inside air escape. This reduces the time it will take the inside of your vehicle to cool down. Your Saturn's air-conditioning may shut off for short periods of time when the engine is under extreme load (steep grades or passing). This is done in order to provide maximum engine performance.

RECIRCULATE: This switch controls the air source (inside or outside) for all modes except Defrost and Defrost/Floor. When this button is pushed (an indicator light will light), the interior air the various air modes. When this button is pushed (an indicator light will light), the interior air is recirculated through the climate control system. This cools the air more quickly and is helpful when you are trying to limit odors entering your vehicle. When Defrost or Defrost/Floor is selected, only outside air is used even though the Recirculate light may remain lit. . Use of Recirculate in cold weather is not recommended and can result in window fogging. In cold or humid weather, outside air is the best for clearing the windows.

Normal A/C: : Push the "A/C" button for normal cooling. When the button is pushed, the indicator light will light. This setting cools air brought in from the outside.

Max A/C: : Provides maximum cooling quickly cool-down on very hot days. Push "A/C" and Recirculate buttons.

Rear Window Defogger

Your Saturn has rear window defogger. Those lines you can see across the rear window are the lines of the heater that warms the glass.

You'll find the control switch on the center of the instrument panel in the area of the heater and air conditioning controls.

To run the defogger, push the switch. Your defogger switch has an indicator light that will glow.

Your defogger will stay on for 15 minutes unless the ignition is turned to either the accessory "ACC" or "LOCK" position or the defogger switch is turned off by pressing the switch again before the 15 minute time period has passed.

To run the defogger for more than 15 minutes, wait until the defogger turns off, and then push the switch again. The defogger will be on for 7 1/2 more minutes.

Your defogger is designed to clear condensation on the inside or outside of the rear window. If there is ice on the outside of the rear window, you may need to scrape it off.

Climate Control System with Automatic Climate Control

Automatic Climate Control System (If Equipped)

The automatic climate control system controls the heating, cooling, and ventilation in your Saturn vehicle automatically. This system also allows you to manually adjust airflow and temperature. To change the temperature display from degrees. Fahrenheit to degrees Celsius, press the AUTO, ECON and MODE buttons simultaneously for 3 to 5 seconds.

Light Sensor

The light sensor (solar load sensor) located on the top of the instrument panel is used by the automatic climate control system. Your automatic control system uses information provided by the light sensor to adjust the temperature in your vehicle. Do not cover this sensor.

Automatic Climate Control Operation

When the system is set for automatic operation, sensors will control the air delivery mode. Air will come from the floor, middle or windshield outlets. The fan speed may vary as the system maintains the selected temperature setting. Be careful not to put anything over the light sensor (solar load sensor) located in the middle of instrument panel near the windshield. The sensor is used by the automatic system to regulate temperature.

To find your comfort zone, start with a 71°F (21.7°C) set point and allow about 2-3 minutes for the system to regulate. Turn the temperature knob to adjust the temperature as necessary in small increments of 1-2 degrees. If you choose a 60°F (16°C) set point, the system will remain at that maximum cooling setting and will not regulate fan speed. If you choose a 90°F (32°C) set point, the system will remain at a maximum heating setting and will not regulate fan speed. Choosing either maximum setting will not cause the system to heat or cool any faster.

With the automatic setting, the air conditioning compressor automatically cycles when needed to cool the air. In cold weather, when the system senses the need, airflow will be directed out through the floor outlets.

As the interior temperature approaches a desired setting, the blower speed will decrease. To maintain interior comfort, the airflow may move to the instrument panel air outlets and the floor outlets (bi-level mode). On bright and sunny days in cod weather, the air flow may come out of the air conditioning outlets (A/C mode) to maintain comfort and prevent stuffiness.

If your vehicle is sitting out on a hot day and you have it set on Auto, the air will flow through the floor outlets for a few seconds to expel hot air from the outlets. This is normal Airflow will resume to air conditioning outlets as the air cools down. If you start the vehicle with the fan setting on HI, it will skip the air conditioning purge.

To avoid blowing cold air in cold weather the system will delay turning on the fan until warm air is available. The length of the delay depends on the outside air temperature engine coolant temperature or the time since the engine was last started. As the engine coolant warms up, the blower speed will gradually increase and air flow from the heater outlets, with some airflow to the windshield to prevent fogging under most normal conditions. If you leave your vehicle, the system will remember the control setting the next time you start the engine.
