What controls the blend door actuator?
The blend door actuator is a small electric motor in your car that controls your car’s climate control system. When you turn the dial to increase or decrease the temperature or flow of air, the signals go through the blend door actuator. It also controls the defrosters and other vents.
What does the blend door actuator connect to?
A blend door actuator is linked to an air control door pivot found on the last drive of the unit; a plastic gear set is frequently rotated from one side to another by the electric motor.An actuator can become faulty if the plastic gear set turns out to be fragile and it breaks.

The actuator is what needs replacing. The arm/hinge that is moving up and down is just the thing you need to grab with your finger to manually flip the blend door over to the hot temp side.
Can a bad blend door actuator drain battery?
The door lock actuator has a battery drain. 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.
Why am I blowing hot air out the drivers side and cold out of the pass side?
Blend door actuators are the most common reason for the car air conditioning to blow cold air on one side and hot air on the other. They can be diagnosed with an advanced scan tool. If it does not move with the adjustments and commands, there is a problem with the blend door actuator and it will need to be replaced.
