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. If your blend door actuator has broken completely, you might get the wrong temperature.
Can you drive with a bad actuator?
Can you drive with a bad blend door actuator? Although a faulty blend door actuator can prevent your climate control system from working properly, the problem will not stop your vehicle from running well.
How much does it cost to fix an actuator?

What does an actuator do in a car?
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.
Can a bad actuator drain battery?
The lock rods are pushed up and down by the auto door locks.The battery runs down when the interior lights stay on longer than normal.It’s a bad actuator if it doesn’t work 100 percent of the time.
Do actuators make noise?
A lot of the noise from a linear actuator comes from the vibration in the actuator housing. As the electric motor runs, it causes vibration throughout the body of the linear actuator. When that vibration makes physical contact with a hard surface area, it will generate a lot of noise as a result.
What causes door actuator failure?
It could be a main door lock switch, broken door wiring harness, bad connector, failed control module or simply a blown fuse.
How do I know if my AC actuator is bad?
Signs You Need A New Blend Door Actuator

- Clicking.
- Any Other Strange Noises.
- Inconsistent Airflow.
- Inconsistent Temperature.
- Wrong Temperature.
How many actuators are in a car?
The different HVAC actuators and their importance
These are the four key actuators that are part of the climate control system in most cars these days: Mode actuator determines where the air will blow out of, such as the floor vents, the top vents, or the defrosting vents that blow onto your windows and windshield.
Where is the actuator located?
The AC actuator is located above or below the coil. It can be set to either single speed or variable speed. When it is not working properly, your AC will be ineffective, and your power bills can skyrocket.
How do I know if my 4 wheel drive actuator is bad?
You will know your 4WD actuator is bad when the 4WD (either 4H or 4L) becomes difficult to engage, gets stuck, or fails to activate. Any of these symptoms means that your actuator is faulty and it should be checked immediately.
Can a bad battery cause door lock problems?

What are the three types of actuators?
What Are Some Different Types of Actuators?
- Linear Actuators. Implied by their name, linear actuators are devices that produce movement within a straight path.
- Rotary Actuators.
- Hydraulic Actuators.
- Pneumatic Actuators.
- Electric Actuators.
- Thermal and Magnetic Actuators.
- Mechanical Actuators.
- Supercoiled Polymer Actuators.
Why is my door locks keep clicking?

Why is my car blowing hot air on one side and cold air on the other?
Due to the design of dual AC systems, low refrigerant is the leading cause of drastic temperature difference from one side of the dash to the other.In most cases after the proper charge of Freon is in the car, the temp will blow equally as cold like it should on BOTH sides!
What does the AC blend door actuator do?
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.
