What Is A HVAC Blend Door Actuator?
The blend door actuator is a small electric motor in your car that controls your car's temperature control system. When you turn the dial to increase or decrease the temperature or flow of air, the signals go through the blend door actuator. It also controls the defrosters and other ac vents.
When you notice some strange noises or you might have difficulty adjusting the temperature in your car, it's necessary to replace the blend door actuator, which can help fixs heating problem and the awful clicking noise.
