Fan Speeds
Air Conditioner
The
fan
control
is
used to select the speed of the blower
fan. There are four speeds to choose from. Moving the
lever to the right or left will increase or decrease the fan
speed. The fan will be off when the system is off.
Temperature
The lower lever changes the temperature of the air
coming through your air outlets. Moving the lever
between COOL and WARM will raise or lower the
temperature.
Off
When the system is off, the ventilation system will allow
air to flow through your Buick when the vehicle is
moving. The system will try to keep the air at the chosen
temperature, unless it is very hot or very cold outside.
When the system is off, the blower fan is also off.
The next three selections cool the air. The air
conditioner won't work well unless all the windows are
closed. On very hot days, open the windows long
enough to let the hot inside air out. This reduces the
amount of work your air conditioner's compressor will
have to do, which should help fuel economy.
The air conditioning compressor operates in all Air
Conditioning positions and the Defrost position when
the outside temperature
is
above 47°F (SOC).
Selecting OFF, VENT or HTR turns off the air
conditioning compressor.
When you don't need to cool the outside air, use the
VENT, HEAT and DEFROST settings. Adjust the
temperature control for comfort. You'll get better fuel
economy (gas mileage) if you're not cooling the outside
air. When you cool the air, your engine runs a
refrigeration compressor, and it has to work a little
harder.
