Ticking noise

Hello, although I can't hear the noise first hand of course, it sounds like you might be hearing the noise of a failed motor in the climate control system. These motors act to change temperature from hot to cold or from dash vent to defroster vent to floor for airflow. If one of these motors fails, the desired temperature for airflow will not happen. It will take some troubleshooting and hands on evaluation to see what's going on for sure, but this is a clue at least. Good luck!
