Is it more of an electric click (as in a relay opening and closing) or more of a mechanical noise?

The noise is likely a broken floor air flap actuator linkage positioned behind the center console to the left side, replaced many of them. The replacement arm is an improved design being a lot stronger. I think it pays around 5 hrs for labor.
