Rear Window Defogger - Pontiac 2001 Montana Owner's Manual

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
the windows, operate the HVAC system in the
OUTSIDE AIR mode.
For additional information, refer to
"RECIRCULATION" earlier in this section.
