Some customers may comment that the HVAC system is not working correctly. When the control is moved to the down or floor (heat) position, air continues to flow from the end vents of the dash.
Air Delivery Improper
The outlets on each end of the dash (1 and 5) are called the side window air (defroster or demister) outlets. The other outlets (6 and 10) are called Air Outlets (Left Side Vent (10) and Right Side Vent (6)) and face the driver or passenger's outboard shoulder.
It should be noted that the Air Outlet Vents (6 and 10) may be closed with the use of the vent thumb wheel if the driver or passenger desires.
For information purposes, the chart is shown.
The table shown represents the design intent for the air distribution from the air outlets in each control setting and the percent of the air flow which should be distributed by the system to the outlets. By design, air should be flowing from the Air Outlet Vents (6 and 10) at all times, except for the Defrost mode.
