Blend Door Actuator Clicking With Car Off

I am worried because i will turn my car off and the noise persist for a while then turn off.

Blend door actuator clicking with car off.

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. The blend door actuator is most of the time at least accessible for testing but sometimes removal of the dash is necessary for replacement. The clicking noise continues even after the car is off. The blend door actuator is located behind the glove box and a sign of failure is an audible clicking sound when you adjust your climate controls.

A blend door actuator is linked to an air control door pivot found on the last drive of the unit. A blend door actuator is made up of an electric motor that turns a plastic gear set in one direction or another which is connected to an air control door pivot at the final drive of the unit. My car has an automatic transmission. Sometimes the fix needs recalibration and sometimes you need to replace the part that is broken.

I won t be able to have a mechanic look at it until the weekend around 5 days from now. Use a test light or power probe and verify that the proper signal is being received to the actuator based on your wiring diagram. An actuator can go bad in of two ways. It s most likely the actuator motor for the blend door in the a c ducts behind the dashboard especially if the noise seems to.

A plastic gear set is frequently rotated from one side to another by the electric motor. Sometimes the clicking will start randomly even though the ac controls are not touched and will often not stop. Is this draining my car battery. A blend door actuator controls the temperature and the flow of the air in a car.
