What does a AC blend door actuator do?
A blend door actuator controls the temperature and the flow of the air in a car. If your vehicle is only releasing cold air, or if you are not able to change the airflow, it may be because of a malfunctioning actuator. Sometimes, the fix needs recalibration, and sometimes you need to replace the part that is broken.
Where is the AC blend door actuator located?
The blend door actuator is typically located closer to the heater core and evaporator than the mode door.
Where is the air conditioner actuator?
The AC actuator is located underneath the dashboard attached to air distribution doors in the hvac box. Doors can control warm air/cold air blending, recirculated/fresh air control, or dual zone splitting. The motors can move the doors into many different positions, or just two.
