Basically, the temperature blend door is the instrument responsible for sending air over the heater when you turn on the heat, and air over the cooler when you turn on the air conditioning. So, if this door isn’t working, you aren’t going to face a terrible accident, but definitely some inconvenient temperatures.
The average cost for HVAC blend door actuator replacement is between $322 and $373. Labor costs are estimated between $193 and $243 while parts are priced at $130. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.
Knocking. Knocking sounds can almost always be attributed to a failing blend door actuator.

What happens when the blend door actuator stops working?
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.

How do I reset my blend actuator?
PRESS and HOLD the DOWN arrow for 10-15 seconds to re-initialize the system. Once complete, the switch should display “027” (Figure 5). Once both sets of control boxes are reset, remove the programable hand switch and install the switch that came with your system.
How much does it cost to get a blend door actuator fixed?
The Average Cost to Replace a Blend Door Actuator Is $309-$355, Depending on if You Go to the Mechanic or DIY. This price range is based on national averages for all vehicles and does not factor in taxes, fees, or your particular make and model.
How do I know if I need a new blend door actuator?
If you find that your car’s temperature is inconsistent or is alternately blowing hot and cold air without you turning the dial, then you may need a new blend door actuator. Unpredictable flow of air: Not only should the temperature of the air stay the same, but it should also come out of the specified vents too.
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.
What makes an actuator stop working?
Normally, failure is caused by application errors, such as side loading, incorrect wiring, poor mounting fixity, excessive loading, and exceeding duty cycle.
What is the lifespan of an actuator?
To summarize, mechanical equipment such as shutdown valves, control valves, actuators, and accessories such as positioners are designed keeping in mind a plant’s life of around 25 years.
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 do you know if your actuator is broken?
Symptoms of a Bad or Failing Door Lock Actuator
Unusual noises coming from inside the door.
Power door locks behave erratically.
Power door locks do not function.
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.
If replacing a blend door actuator, check to make sure the blend door position is completely closed before installing the new blend door actuator. If the blend door is left open, even slightly, the temperature inside the vehicle will not match the A/C temperature selected.
Is blend door actuator covered under warranty?
This letter is to inform you that the warranty period (3 years or 36,000 miles) on your vehicle’s Heater Ventilation Air Conditioning (HVAC) Blend Door Actuator has been extended to 5 years/60,000 miles.
What’s the difference between a blend door actuator and an air door actuator?
The blend door actuator is typically located closer to the heater core and evaporator than the mode door. Mode Door Actuator: The mode door actuator controls which vent(s) air blows through. The door on this actuator has two positions: closed and open.
Does the blend door actuator control AC?
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.
Are there two blend door actuators?
The blend door actuator decides whether the air is going to come through the mid-vent, floor vents, and control defrost, and so on. Some cars have a dual blend door actuator that enables the driver to control the climate in different time zones.
Which actuator controls the heat?
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.
