Temperature Blend Air Door Actuators: The temperature blend air door actuator controls the temperature of the air flowing from the vents by mixing hot and cold air from the heater core and the evaporator.
A faulty actuator can cause the blend door to be stuck in one position or another, resulting in an outlet temperature that’s hotter or colder than the desired setting.
Can a blend door actuator affect the AC?
Incorrect temperature: This is one of the more common symptoms of a defective blend door actuator. If your car’s temperature won’t heat up when you want it to, the air conditioning won’t expel cool air or it will only get so hot or so cold, then it’s probably the blend door actuator.
Actuators work behind the scenes in vehicles to convert energy into a physical action or force. They perform a variety of performance and convenience functions, from controlling the throttle to directing airflow in the climate control system, and operating power seats and liftgates.
What is the purpose of the air door actuator? – Related Questions
What causes a door actuator to fail?
There are several factors that can cause a door lock actuator to fail. One is corrosion. Over time, moisture, oil, dust, and debris can enter the actuator or the mechanical links.
What happens when your actuator goes out?
The most common symptom of the A/C Actuator going bad or when the Blend Door is stuck is when you feel inconsistent air flow coming in. The desired air you want whether it be hot or cold, is being diverted incorrectly, so you are not getting a consistent temperature out of the A/C system.
How much does it cost to replace a car actuator?

How do I know if my actuator is working?
How do you test if an actuator is working?
To test a linear actuator’s current draw, simply connect a multimeter in series with one of the leads of a powered linear actuator, and watch the amperage reading as you extend/retract the rod. Based on the reading, you can determine a power supply that will be able to handle that current draw.
How much does it cost to replace an air actuator?
The average cost for HVAC air door actuator replacement is between $421 and $478. Labor costs are estimated between $218 and $275 while parts are priced at $203. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
How many air actuators does a car have?
Typically, vehicles have 3 or 4 actuators. Vehicles with rear controlled HVAC will often have additional actuators to control the auxiliary unit, bringing the total per vehicle to as many as 6.
How long do car actuators last?
In the majority of cases the throttle kicker actuator will last the lifetime of your vehicle without any service or maintenance needed on your part. However, when it does fail it is usually very sudden and completely unexpected.
