Solved: Mystery Switch

Hello,

We just brought home our first Heartland camper. It is a 2022 Mallard M251BH.

There are 3 main rocker switches right inside the door. 1st is main interior lights, 2nd awning light, 3rd no clue. I have tried it during night to see if it’s exterior but no luck. I also checked all interior lights if they were overrode manually. I did check exterior outlets and confirmed it is wired.

Any clues to what this switch controls?

Thanks

Is it the step light? Stand outside and look at your steps. Is there a light in the back of the step box that is controlled by that switch?

Is there an outside electric receptacle box near one of the awning legs? A similar one on my rig controls the “Awning outlet”
 
That was it! Was able to pull voltage off the non terminated wires for the Winegaurd Gateway.
I took out that switch and when I disconnected the bottom (off position) the fan for the ac shut off. It doesn't change when I put it on or off. Fan stays on. Not sure why. Nothing changes with the antenna either. I did a channel search with the switch on and off and find same amount of channels. I have better luck with an HD antenna that with the Winegard antenna. I think it's junk IMHO. Place I bought it from doesn't even know
