Rear Heating System - Chevrolet 2003 Express Van Owner's Manual

If your vehicle has air conditioning, your heating/air
conditioning 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.
(Temperature Control): Turn the center knob clockwise
or counterclockwise to increase or decrease the
temperature inside your vehicle.
A/C (Air Conditioning): This setting will begin to cool
and dehumidify the air inside of your vehicle.
MAX
A/C
(Maximum Air Conditioning): Turn the right
knob to MAX A/C for maximum cooling. This setting
cools the air the fastest, by recirculating the inside air.
Rear Heating System
Your
vehicle may have an optional rear heating system
that allows you to adjust the amount of air flowing
into the rear of the vehicle, from the front-seating area.
This feature works with the main climate-control
system in your vehicle.
