What would be really "cool" would be to have it on a servo motor so the grille could close by an amount that would hold the temps at a pre-determined level. As you'd drive through cold pockets of air, it would close slightly and vice versa. Awesome!

Good point and cool idea.

I don't think just any grille block design would work with a door lock actuator. At some point I imagined having just a cover that hinges forward to open, but I think a door lock actuator wouldn't have any holding force once the voltage is removed. Maybe a grille block with a sliding slotted door would be good.
