Many S197 Mustangs are plagued with HVAC air door actuators that fail after a few years of service. Often times you get an audible "clicking" noise coming from your center console or behind your radio. Other times adjusting your A/C defrost/panel/floor settings will not allow you to switch air flow directions. If you experience any of these problems more than likely your Mustang has experience an air door actuator failure.
These replacement Mustang air door actuators are the ultimate solution to get your A/C functioning and flowing like it did when it drove off the showroom floor.
The 2005-2009 Mustang features two of these actuators:
The one on the LH side of the center A/C "stack" controls the panel/floor door.
The one on the RH side of the center A/C "stack" controls the defrost door.
