Rear Window Defogger - Pontiac 2002 Aztek Owner's Manual

Defogging and Defrosting
To rapidly defrost the windshield, move the temperature
control to the red area and turn the mode knob to
defrost. Adjust the fan to the highest speed.
To keep the windshield clear and bring in heated air
through the floor ducts, turn the mode knob to defog.
When the temperature outside is above freezing, the air
conditioner compressor will run in these settings to help
remove moisture from the air.
Your vehicle is equipped with side window defogger
vents located on the top of the instrument panel. For
additional side window defogging, turn the mode knob
-
to the bi level setting and adjust the fan to the highest
speed. Aim the side vents on the instrument panel
toward the side windows. For increased airflow to the
side vents, close the center vents.
Operating the HVAC system in the recirculation mode
may cause fogging of the vehicle's windows when the
weather is cold and damp. To clear the fog, switch the
HVAC system to either the defog or defrost mode and
increase the fan speed. To avoid re
windows, operate the HVAC system in the outside
air mode.
For additional information, refer to "Recirculation"
earlier in this section.
