Rear Window Defogger (If Equipped) - Oldsmobile 1999 Cutlass Owner's Manual

If you select RECIRCULATION while in the VENT,
BI-LEVEL or FLOOR modes, humid air can recirculate
inside the vehicle and allow moisture to form on the
windows. If this happens, either press the A/C button to
on or select DEFROST or the DEFOG modes.
Your vehicle is equipped with side window defogger
outlets. The side window defogger outlets are located on
the outside of the side instrument panel outlets. To defrost
the side windows turn the temperature control knob all
the way in the red area. Use FLOOR and adjust the fan to
the highest speed. To control fogging of the windows turn
the temperature control knob all the way to the red area.
Use DEFOG and adjust the fan to the highest speed.
To defog the side windows while using air conditioning
-
use BI LEVEL and adjust the fan to the highest speed
and press the A/C button. For added airflow to the side
windows aim the side vents toward the windows and
close the center outlets.
RECIRCULATION will not work in DEFROST and
DEFOG. This is done to prevent recirculation of humid
inside air and allow the system to work properly.
