Side Window Demisters
A side window demister outlet is at each end of the
instrument panel. These nonadjustable outlets direct air
toward the side windows when the system is in either the
FLOOR, MIX, or DEFROST mode. The air is directed at
the area of the windows through which you view the
outside mirrors.
