What does the actuator on an AC heater do?
Also called HVAC actuators, these small electric motors control the flow and blend of hot and cold air to the passenger areas by opening and closing the vent doors that let the air through. When one of these stops working, you may either get cold air but no hot air or there will be hot air with no cold air.
How does a climate control actuator work in a car?
They also control hot and cold settings for right and left passenger compartments. Your car’s climate control computer gives an electrical command to the actuator to start moving the actuator motor to change air direction modes. This direction is according to the temperature chosen by the driver or passenger on dual climate control systems.
How does heat actuator work on Chevy Tahoe?
INSANE!!!!!!! During normal driving with a/c on, the air coming out of the vents on driver’s side changes from cool air to warm as if you have turned on the heat. The air coming out of the passengers vents are still putting out cold air.
What does the actuator on a jeep do?
The actuator is responsible for moving the air direction and temperature doors inside the heater plenum; their job is to manage mode settings like re-circulation modes, mid vent, defrost and fresh air, floor as well as temperature. Also, they control the cold and hot settings for left and right passenger sections.

How does a climate control actuator drive the motor?
The motor is driven by applying power and ground for the desired movement. The polarity is reversed to change direction. The HVAC control head usually provides the voltage, and in most cases, it’s somewhat lower than system voltage. Most ECC actuators contain a potentiometer that’s geared to the motor’s drivetrain.
Why do I have a problem with my actuator?
It helps control the temperature and air flow within the vehicle. When you have a problem controlling the temperature of the air circulating in your car, or if you can’t stop it from shooting out full blast, there’s a good chance that you have a problem with your actuator. Actuator is basically another word for motor.
How does an air blend door actuator work?
An air blend door actuator is constructed from a plastic housing, a small electric motor and a plastic gear set. A door position sensor is also incorporate into the unit to send feed back information to the climate control computer.
