2022 Elkridge 37DRB- master bedroom – has two switches on the wall under the thermostat- left one controls the lights- right one…. I have no clue.
Pull the switch out and verify that it’s actually connected to something.
Have you tried when it’s dark inside the trailer? It’s probably a closet or accent light. Have someone switch it off and on while someone else walks around looking.
There was a night light right by our entry stairs and on on floor board in bathroom. This switch worked for both night lights.
Look on ceiling for a wifi prep! It might work that
Looks like it should be to another light. Maybe an accent light near the floor or light above the slide room. Have you flipped it on and off at nighttime?
