Defogging And Defrosting - Chevrolet kodiak 2004 Owner's Manual

If your vehicle has air conditioning, the controls will look
like this:
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
<
(Maximum Air Conditioning): Turn the right knob
to this setting for maximum cooling. This setting puts
the system in recirculation mode and helps to maximize
your air conditioner's performance and your vehicle's
fuel economy. This setting also cools the air the fastest.
3-20
Y
(Air Conditioning): This setting is used for normal
cooling on hot days. It cools outside air and directs
it through the instrument panel vents.

(Bi-Level Air Conditioning): This setting divides
airflow between the floor vents and instrument panel
vents. The air conditioning compressor will cycle
continuously in this setting as long as the outside
temperature is warm enough to activate the compressor.

Defogging and Defrosting

Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control is used properly.
There are two modes to clear fog or frost from your
windshield and side windows.
Use the defog mode to clear the windows of fog or
moisture and warm the passengers. Use the defrost
mode to remove fog or frost from the windshield more
quickly. For best results, clear all snow and ice from the
windshield before defrosting.
