What Is A Blend Door Actuator?
The blend door actuator is a small electric motor in your car that controls your car's climate control system. It looks like a small plastic box with a few plastic gears on the inside. It is so small that you could easily fit it in one hand if you were attempting to remove it. However, if you aren't an experienced mechanic or technician, you might have a hard time identifying it.
It also has a very important job. 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 vents.
There can also be two blend door actuators in your car if you have a newer model. If your backseat has controls to the temperature and airflow intensity, then your car will have two blend door actuators.
Signs You Need A New Blend Door Actuator
- Knocking
Knocking sounds can almost always be attributed to a failing blend door actuator. When you start your car or the AC system, the knocking sound will start, and that's when you know that you need to get your blend door actuator replaced. - Clicking
Another sign that you might have issues with your blend door actuator is a clicking sound coming from the dashboard. It could be loud or faint, but it will be constant and repetitive. The sound will be coming from the area where your HVAC controls are on your dashboard. If you notice a clicking sound, book an appointment with a professional right away. - Any Other Strange Noises
There are other noises that you might be noticing that could be indicating there's an issue with your blend door actuator. If you hear a droning or squeaking sound coming from the center of your dashboard, there is most likely something wrong with your blend door actuator. These sounds will usually get louder when you turn on your AC or change the temperature. Got other strange noises? Click here to see why your car might be making a weird noise. - Inconsistent Airflow
If your airflow coming from your vents isn't consistent, there could be a problem with your blend door actuator. This happens because the blend door is moving back and forth, diverting the airflow and causing inconsistent airflow to come out of your vents. - Inconsistent Temperature
If the temperature of air coming out of your car's vents is inconsistent, meaning it changes between hot and cold without touching the controls, that could be a sign that your blend door actuator isn't working properly. - Wrong Temperature
If your blend door actuator has broken completely, you might get the wrong temperature. Try blasting cold or hot air and, under normal circumstances, the air should come out according to your controls. If you are trying to blast cold air, but it is coming out hot, even after giving your car a few minutes to adjust, then that is a pretty good indication that you need a new blend door actuator.
Can I Drive With A Faulty Blend Door Actuator?
Technically, you can continue to drive safely with a broken or faulty blend door actuator, but we wouldn't recommend doing it for long periods of time.
The blend door actuator doesn't affect how your car drives as it is purely a feature of comfort inside the main cabin. When it breaks, you might notice some strange noises or you might have difficulty adjusting the temperature in your car which can be very inconvenient. It can make the car ride uncomfortable and annoying for both you and your passengers. That's why we recommend handling this issue as soon as it arises.
