Is my Hvac control head bad

What is your question?

I have pulled out the blend door Actuator. It cycles when the vehicle is turned on, so there is power to it. The temperature slide does not move it when it is changed from cold to hot and vice versa. The temperature slide for the driver side works correctly. Is it the control head temperature control for the passenger side? Is there a fix?

How long has your 2003 Chevrolet Silverado 2500 HD had this problem?
