Blend Door Actuator: Description
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
The blend door actuator is a reversible, 12-volt direct current (DC), servo motor which mechanically positions the blend-air door. The blend door actuator is located on the bottom of the HVAC housing. See Fig 1.
The blend door actuator is interchangeable with the actuator for the mode-air doors. The each actuator is contained within an identical black molded plastic housing with an integral wire connector receptacle. Each actuator also has an identical output shaft with splines that connect it to its respective door linkage and three integral mounting tabs that allow the actuator to be secured to the HVAC housing. The blend door actuator requires mechanical indexing to the blend door linkage.
