all the motors are working i can hear the actuator turning from dash to defrost

Hello, If you have a blend door or mode door that is broken, the actuator may turn, but the door will not change the direction of air. Also, if the actuator is not properly coupled to the mode or blend door, the motor turning will have no effect on the blend door or air flow. If this is your issue, you will likely need to remove the actuators to inspect the condition of these components.
