Radiator Louvers - How do they operate?

[onebadjon]

Question for the Group: Just purchased a 2023 Lariat ER. Love this F-150. How does the Radiator Louvers work in the lower front of the F-150? By temperature? thermostat? I was able to open and close the louvers by hand when off and not hot.
Is there a switch or button somewhere? Nothing in the owner's manual and the dealer does not know (at least not the sales rep. or sales manager).

They operate automatically, opening and closing, partially or full, as the truck needs them to be. Nothing for you to do.

My 2024 Lightning louver is open when the truck is off and when I turn it on you can hear the fan working.
