Outlet Adjustment - Buick 2004 Regal Owner's Manual

Use the WINDSHIELD/FLOOR 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. For best results, clear all snow
and ice from the windshield before defrosting.

FRONT (Defrost): This setting brings in outside air
and directs most of the air through the defrost outlet.

window outlets. The indicator light on the button will
come on and WINDSHIELD will be seen on the display.
To defrost the windows quickly, press the FRONT
button, set the temperature to 90°F (32°C), select a high
fan speed, and turn the DUAL button off.
To warm passengers while keeping the window clear,
push the AIR FLOW button to select
WINDSHIELD/FLOOR which will appear on the display.
Select a fan speed.
The air-conditioning compressor will run automatically in
this setting unless the outside temperature is below
40°F (4°C).
Do not drive the vehicle until all windows are clear.

defogger on or off. It will initially turn off after about
