Window Defog
When the FRONT window becomes fogged and the regular blower is not enough to clear it, press
this button. All air-conditioning blowing will be forced through the window-vents for maximum
effectiveness.
This feature is commonly referred to as the “defroster”.
When the REAR windows become fogged, push this button to activate the electric warmer (those
metal wires attached to the glass) to clear them. This will also melt any snow that has accumulated
on the outside of the winter.
This feature is commonly referred to as the “rear defroster”.
Fan Options
To adjust the fan speed, use this rocker-switch to make it
faster or slower.
Also, pressing either side of this when the blower fan off
will turn it on.
This illuminated display shows what speed the blower fan is set to.
Note that in some circumstances heating can be more effective if
the speed isn’t maximum, since slower air passing through the
heater-core can transfer more warmth.
