    AC / Heater clicking when adjusting hot / cold to center point

    Hi all, my vehicle switches between hot and cold flow without issue, but if I leave it in the middle I hear a constant clicking that does not sound good. I'm assuming the car uses a sort of mixer valve, but I don't understand why the motor would be still trying to move after it has been set. Is this something thats fixable or common or goes away, or is it not worth tearing into the dashboard to replace an obscure part

    What do you mean by leave it in the middle? The temperature or fan on the climate cintrol?

    Why would you leave it in the middle? It either goes up to red or down to blue...
