Operation Tips
•
Clear away any ice, snow or leaves from the
air inlets at the base of the windshield that
may block the flow of air into your vehicle.
• Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
• Keep the path under the front seats clear of
objects to help circulate the air inside of your
vehicle more effectively.
• If the airflow seems low when the fan speed is at
the highest setting, the passenger compartment
air filter may need to be replaced. For more
information, see Passenger Compartment
Air Filter on page 3-32.
Rear Air Conditioning System
If your vehicle has the rear air conditioning system it has
two fan speed selectors. One fan speed selector is
located in the front overhead console and the other is
located in the headliner above the second row seats. The
rear air conditioning system is designed to provide cooled
air only. There is no heating provided with this system.
To operate the rear system using the front control,
just turn the knob to the fan position you want.
To use the rear control, first turn the front control to
the AUX position. Then, the rear control can be used
to increase and decrease the airflow.
