Subsequently, How many actuators are there in a car? 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. DID YOU KNOW?
How do you test an AC actuator?
Yet, Can a bad AC actuator drain battery? When the control module is malfunctioning, one possible outcome is for the AC actuator to not know when to open or close. This can continue draining the battery once the car is off, which can lead to a surprise dead battery upon re-entering your car.
What actuator controls the vents? The mode door actuator controls which vent(s) air blows through. The door on this actuator has two positions: closed and open. Today, most actuators are controlled electronically. As actuators wear over time, the plastic gears inside may be stripped or broken, causing them to fail.
How do you change an AC actuator?
Where is the AC blend door actuator located?
The blend door actuator(s) are typically located on the climate control case behind the dashboard.

How much is a actuator cost?
The average car actuator replacement cost is $300, depending, of course, upon your car’s make and model. In most cases, a mechanic will remove the malfunctioning actuator and replace it with a functioning one.
What happens when an AC actuator goes bad?
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.

Why do blend door actuators fail?
Another common cause of a blend door actuator failure is a faulty motor. The motor is responsible for turning the gears that move the blend door. If the motor fails, the actuator cannot move the door. The most common symptom of a faulty motor is a clicking noise coming from the dash and wrong temperature selection.
