Why do I have a problem with my actuator?
It helps control the temperature and air flow within the vehicle. When you have a problem controlling the temperature of the air circulating in your car, or if you can’t stop it from shooting out full blast, there’s a good chance that you have a problem with your actuator. Actuator is basically another word for motor.
How are temperature actuators used in a heater?
Temperature actuators blend the cooled air with warm air to achieve the temperature we want. They do this by allowing some air to flow through the heater core, after flowing through the evaporator core. The dual-zone system adds more actuators and doors.
What kind of motor does a temperature control system use?
Today, most temperature control systems use digital circuits and electronic actuators. The actuator contains a small motor, gears and a feedback circuit to report the current position of the output shaft. Actuators use 12 volt direct current motors and pulse-width modulated stepper-motors.
How are actuators used in dual zone systems?
Dual zone system may have two or more blend actuators. The fresh/circulate actuator controls inside and outside air used in the system. Sometimes also called fresh air re-circulate. A Heater control actuator can control heater flow. On some systems this is controlled by the mode actuator.
How to calibrate an ATC door actuator?
The HVAC menus include a actuator calibration function that is run after repairs are made to any of the HVAC doors, linkage, door actuators, or door actuator circuits. This is required to calibrate ATC (automatic temp control) systems. 1. Turn the ignition on. 2. Turn the blower control to off. 3.
How to test blend door actuator, climate control, heater?
In some cases you can manually test the blend door actuator in others you can use computer for the diagnostics. There are usually a few blend door actuators that are part of the hvac system. This way you will know which blend door is bad and needs to be replaced. ► Like Us on FACEBOOK: https://www.facebook.com/worldmechani…
How does mode actuator failure affect your car?
Besides the air not blowing from the proper vents, there may be other symptoms of failure in the climate control system to be aware of. These symptoms are especially concerning when the warm summer months hit. If the problem is due to a mode actuator failing, then the entire actuator will need to be replaced to fix the problem.
What happens if there is no DTC on the a / C heater?
If there are active or stored DTCs to display, the A/C status indicator (3) will begin to flash. If there are no active or stored DTCs to display, the LEDs on the A/C heater control (4) will turn off and the system will automatically exit the mode of operation.
Why is my Blend door actuators not working?
If your experiencing an air conditioning issue on one side of the cabin, whereas one side works perfectly fine, but the other side only blows out hot air – or you are experiencing an issue where both sides of the cabin can only go to 100% airflow or no airflow at all but nothing in between, it is probably your blend door actuators.
Why does my car make a knocking sound when I open the door?
When you start the car, or just the AC system, and notice a knocking sound like someone tapping on your door, that is indicative of a problem with the blend door actuator. Inconsistent Airflow: If the blend door is moving back and forth, then the airflow will be diverted incorrectly or maintained incorrectly.
What are the symptoms of a bad door lock actuator?
3. Power door locks do not function. Another symptom of a potential problem with the door lock actuators are power door locks that do not function. If the door lock actuators fail, they will disable the power door lock feature from working.

Actuator is basically another word for motor.
What causes a door lock to stop working?
If the actuators have any sort of internal or wiring issue, it may cause them to rapidly lock and unlock unexpectedly, or cause them to function intermittently. 3. Power door locks do not function
When do you know something is wrong with your blend door actuator?
Noise: If you’re hearing a sort of droning or squeaking repetitive sound from somewhere within your dashboard around the Center area, in the more or less general area that you are control knobs for the HVAC system are located, that’s a good sign there’s something wrong with the blend door actuator.
How does a manually operated valve actuator work?
Manually operated valves require someone in attendance to adjust them using a direct or geared mechanism attached to the valve stem. Power-operated actuators, using gas pressure, hydraulic pressure or electricity, allow a valve to be adjusted remotely, or allow rapid operation of large valves.
What does a blend door actuator look like?
The blend door actuator itself is a very small plastic box. There are a couple of plastic gears inside, the electronics, and then the plastic case that houses the whole thing. It’s a very small piece of technology, you can fill it easily in your hand if you were to remove it.
Which is the leading manufacturer of electric actuators?
AUMA automates valves AUMA has been developing and building electric actuators and valve gearboxes for 50 years and is now one of the leading manufacturers in the industry. read more
