Hi and thanks for using 2CarPros.com.
When do you hear the noise? Is it while driving or after it is parked?
Let me know. Also, if it is a ticking noise you hear, it could be a blend or mode door actuator. They commonly go bad and create a ticking. Take a look at this link to see if it is describing what you hear.
Let me know.
