Another Switch Question

[Springer]

We have a 2021 M260 Mallard. There are three switches in a row over two. Bottom ones are easy (slide & awning) the top ones are the first is main lights, second is the awning light strip (so I guess that would be the porch light) and the third I have no clue. Any help would greatly appreciated.
On or Off I cannot find a change in the daylight or dark.

Pull the switch panel to see if anything is connected. I've seen a post or two on here that folks have unused switches.

Any idea what it should be? Have found a few other items that are missing. No radio antenna, lol.

No clue. I have unmarked switches on my fifth wheel that I still get confused on what switch does what, but they are all for lights. Some are tied in to the ceiling lights with the switch built in, but too high to toggle without a ladder.

One thing to try, if you have a wall mounted light switch nearby, turn that on and see if the switch controls it...also, check exterior lights.
