Dorman - OE Solutions HVAC Blend Door Actuator P/N:604-938
Keep cabin airflow under control with the Dorman hvac heater blend door actuator 604-242, an electric motor that repositions the MAIN-position air door inside the HVAC case to direct airflow to your vents; Dorman lists it as a mode air door actuator. It fits many vehicles as a direct-fit replacement, among them the 2009-2010 Ford F-150, 2010-2014 Ford Mustang and 2008-2012 Ford Escape — see the Buyer's Guide tab for the full list and engine-level fitment.
Signs the original actuator may need replacing include a clicking or knocking noise behind the dash or airflow stuck on one setting. If a failed MAIN air door actuator is the cause, this Dorman air door actuator replaces it — diagnose the concern first, as these symptoms can have other causes.
