GM Service Manual Online
For 1990-2009 cars only

Your vehicle has air outlets located in the center and on the side of your instrument panel that allow you to adjust the direction and amount of airflow inside the vehicle. Move the louvers up or down. Use the thumbwheel next to or underneath the outlet to close the louvers. For the most efficient airflow and temperature control, keep the outlet in the fully opened position.

Operation Tips

    • Keep the hood and front air inlets free of ice, snow, or any other obstruction, such as leaves. The heater and defroster will work far better, reducing the chance of fogging the inside of your windows.
    • Keep the air path under the front seats clear of objects. This helps air to circulate throughout your vehicle.
    • Adding outside equipment to the front of your vehicle, such as hood-air deflectors, etc., may affect the performance of the heating and air conditioning system. Check with your dealer before adding equipment to the outside of your vehicle.
