Blend Door Actuator FAQ
The blend door actuator(s) are typically located on the climate control case behind the dashboard.
How do I know if my blend door actuator is working?
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.
What happens when blend door actuator fails?
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.
Where is 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 you reset a blend door 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 do you know if your blend door is stuck?
One of the most common signs of a blend door problem is when the defrost is turned on, but it takes a while to get going. Most of the time, the windshield won’t defrost, does so slowly, or remains foggy after a while.
What is an actuator and where is it used?
An actuator is a device that uses a form of power to convert a control signal into mechanical motion. From electric door locks in automobiles, to ailerons on aircraft, actuators are all around us.
Which on the system is the actuator?
An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve. In simple terms, it is a “mover”. An actuator requires a control device (controlled by control signal) and a source of energy.
Is actuator internal or external?
An actuator is a machine, or rather a part of a machine used to convert externally available energy into motion based on the control signals.
What is actuator used for?
An actuator is a device that produces a motion by converting energy and signals going into the system. The motion it produces can be either rotary or linear. An electric linear actuator is a device that produces a motion by converting energy and signals going into the system.
How many 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.
What causes an actuator to fail?
Normally, failure is caused by application errors, such as side loading, incorrect wiring, poor mounting fixity, excessive loading, and exceeding duty cycle.
What are the three types of actuator?
The three main types of actuators are pneumatic (air pressure), hydraulic (fluid pressure) and electric.
- Pneumatic Actuators.
- Hydraulic Actuators.
- Electric Actuators.
- Example of Actuator Use: Gripping.
What is the most common actuator?
The most common kind of actuator is an electrical one which can take electrical energy from DC or AC and turn it into mechanical energy. Because this is a clean and easily available technology, electrical actuators are popular for many types of industry and things like multi-turn valves.
What is difference between sensor and actuator?
The main difference is that the sensors pick physical gestures from their environment and convert them into electrical signals- while actuators pick the system’s electrical signals to convert them into physical gestures (heat, sound, electricity, etc.).
How can you test actuators?
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.
Do actuators have fuses?
In order to prevent equipment failure there are several key components to consider when outfitting your actuator or electric motor with the proper fuse. The first of these components is sizing your fuse for the correct electrical draw so knowing your motor is imperative.
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.
What are the four types of actuators?
There are four basic types of linear actuators: mechanical/electro mechanical, hydraulic, pneumatic and piezoelectric.
