Hi and thanks for using 2CarPros.com.

It sounds like you have a problem with the mode door actuator. Take a look through this link which describes what is most likely happening.

If you determine it is the actuator, here is a link that shows generally how they are replaced:

Let me know if this helps.

Take care,
