There's no telling how long a blend door actuator will last since carmakers don't really specify their lifespan. However, it should last the car's lifetime and it's one of those car parts that rarely goes wrong.
If those setting are not allowing heat to come to one side of the cabin, the blend doors are likely to blame. These are small doors inside the climate control duct work that are run by small servomotors to control how the air temperature interacts with the cabin.
If you experience the symptom of the AC blowing hot or cold air on one side but not the other and it's accompanied by a clicking or ticking sound from the dashboard, it probably means a gear in the temperature blend door actuator is faulty and the actuator needs to be replaced.
Electric linear actuators are driven by either an AC or DC motor.
We can determine the maximum current the actuator can consume by measuring the resistance between these 2 leads. 12volts/resisitance(in ohms) will give you the maximum current draw. So if you measure 1 ohm then the current draw is 1 amp for 12 volts.
The typical current draw is 30-40mA on 24 Vdc units and 15-20mA on 12 Vdc units when not in 'sleep mode.
For screw-driven linear actuators (pictured right), change the lead screw's pitch to increase speed. For example, instead of using a standard 10×2 pitch, increase it to 10×5, 10×10 or even 10×50. That way, for every rotation of the lead screw, the carriage can travel that much farther.
Linear motors operate with an AC power supply and servo controller, which are often the same as those used for rotary servo motors. The linear motor primary part is connected to the power supply to produce a magnet field. By changing the current phase in the coils, the polarity of each coil is changed.
Linear motors are widely used. One of the major uses of linear motors is for propelling the shuttle in looms. Linear motors have been used for sliding doors and various similar actuators. Also, they have been used for baggage handing and even large-scale bulk materials transport.
Working Principle of Linear Induction Motor Electric current gets induced in the conductors of the secondary due to the relative motion between the traveling flux and the conductors. Then the induced current interacts with the traveling flux wave to produce linear force or thrust.
