DESCRIPTION
All models use a blend-air system. Outside air enters heater through cowl opening and passes through a plenum chamber to heater core. Blend air door in heater housing controls temperature by either directing air through or around heater core. Air flow is then directed through dash panel to air distribution duct in passenger compartment.
On Durango, air taken from the front heater system is fed back through an air duct into the center console. At the rear of the center console, passengers can operate a 3 mode switch to adjust air flow. Temperature and blower speeds are controlled by the front heater control panel.
| WARNING | To avoid injury from accidental air bag deployment, read and carefully follow all SERVICE PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM procedures in AIR BAG SYSTEM SAFETY article in GENERAL SERVICING. |
