2004 SATURN L-SERIES air conditioning

Operation
To change the current mode, turn the right knob to
select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, and then directs most of
the remaining air to the oor outlets. Some air may be
directed toward the side windows.
6(Floor):This mode directs most of the air to the
oor outlets with some air directed to the side window
outlets.
The right knob can also be used to select defog or
defrost modes. Information on defogging and defrosting
can be found later in this section.
A(Fan):Turn the knob in the center of the system
clockwise or counterclockwise to increase or decrease
the fan speed. The fan must be on to run the
air-conditioning compressor.Temperature Control:Turn the left knob clockwise or
counterclockwise to increase or decrease the
temperature inside your vehicle.
?(Recirculation):This mode keeps outside air from
coming in the vehicle. It can be used to prevent outside
air and odors from entering your vehicle or to help cool
the air inside your vehicle more quickly. Press this button
to turn the recirculation mode on or off. When the button
is pressed, an indicator light above the button will come
on to let you know that it is activated. The air-conditioning
compressor comes on. The recirculation mode can be
used with vent, bi-level, or oor modes, but it cannot be
used with the defog or defrost modes. When you switch
to the defog or defrost modes the system will
automatically move from recirculation to outside air.
When you move the mode knob back to another mode,
the system will move back into recirculation. When the
car is turned off and back on the system will default to
outside air automatically.

AC (Air Conditioning):Press this button to turn the
air-conditioning system on or off. When A/C is pressed,
an indicator light above the button will come on to let
you know that air conditioning is activated.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days, do the following:
1. Select the vent mode.
2. Select the highest fan speed.
3. Select A/C.
4. Select the recirculation mode.
5. Select the coolest temperature.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
The air-conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to choose from to
clear fog or frost from your windshield. Use the
defog mode to clear the windows of fog or moisture and
warm the passengers. Use the defrost mode to
remove fog or frost from the windshield more quickly.
Turn the right knob to select the defog or defrost mode.
-(Defog):This mode directs half of the air to the
windshield and half to the oor outlets with a small
amount directed to the side windows. When you select
this mode, the system turns off recirculation
automatically and runs the air-conditioning compressor
unless the outside temperature is at or below freezing.
The recirculation mode cannot be selected while in
the defog mode. Do not drive the vehicle until all the
windows are clear.
1(Defrost):This mode directs most of the air to the
windshield with some air directed to the oor vents.
In this mode, the system will automatically force outside
air into your vehicle and run the air-conditioning
compressor. Recirculation cannot be selected while in
the defrost mode.

Automatic Operation
To switch the temperature display from degrees
Fahrenheit to degrees Celsius, press and hold the
AUTO, ECON, and MODE buttons at the same time.
AUTO (Automatic):When automatic operation is active
the system will control the inside temperature, the air
delivery, and the fan speed.
OFF:Press this button to turn off the entire climate
control system. Outside air will still enter the vehicle.
Use the steps below to place the entire system in
automatic mode:
1. Put the fan knob on AUTO and press the AUTO
button.
When AUTO is selected, the display will change to
show the current set temperature, delivery mode
and fan speed.
When auto is selected, the air conditioning operation
and air inlet will be automatically controlled. The
air conditioning compressor will run when as
necessary. The air inlet will normally be set to
outside air. If it’s hot outside, the air inlet may
automatically switch to recirculate inside air to help
quickly cool down your vehicle. The light on the
button will illuminate in recirculation.2. Set the temperature.
To nd your comfort setting, start with a 71°F (22°C)
temperature setting and allow about two to three
minutes for the system to regulate. Turn the
temperature knob to adjust the temperature setting
as necessary. If you choose the temperature setting
of 60°F (15°C) the system will remain at the
maximum cooling setting. If you choose the
temperature setting of 90°F (32°C) the system will
remain at the maximum heat setting. Choosing either
maximum setting will not cause the vehicle to heat or
cool any faster.
Be careful not to cover the sensor located on the
top of the instrument panel near the windshield. This
sensor regulates air temperature based on sun
load, and also turns on your headlamps. See
“Sensor” later in this section for more information.
To avoid blowing cold air in cold weather, the
system will delay turning on the fan until warm air is
available. The length of delay depends on the
engine coolant temperature. Pressing the fan switch
will override this delay and change the fan to a
selected speed.
