Blend Door Actuator: Description
WARNING: This page is about a different car, the 2005 Jeep Liberty. 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. See Fig 1. The blend door actuator is located on the top of the HVAC housing.
The blend door actuator is contained within a black molded plastic housing with an integral wire connector receptacle and three integral mounting tabs that allow the actuator to be secured with three screws to the HVAC housing. The blend door actuator also has an output shaft with splines that connects it to the linkage that drives the blend-air door. The blend door actuator requires mechanical indexing to the blend door linkage.
