Rich,
You are absolutely correct that that is where it SHOULD be, but there is no switch there.
We visited with a Sunstar owner in the park here yesterday who had a longer model, not the 27N, and there was a labeled switch right by the door, but ours is a totally different floor plan.
All the other lights in the coach work, and every switch we can find lights something. There are no extra switches on the dash or anywhere that don't do what they are labeled to do. There are four switches by the steps, in the footwell, i.e., chassis battery disconnect, coach battery disconnect, stairs off, and awning. All work as labeled. There are three switches on the back of the kitchen cabinet, also facing the entry door which are not labeled, but all three work interior lights. Two are overhead kitchen light banks, and the third lights a small nightlight by the floor. Could this possibly be the switch that also lights the porch? It would make sense that this nightlight and porch light could be connected as an indicator that the porch light was on. I'll check the bulb in the porch light to see if it is burned out since it does not come on when the nightlight is on.
Thanks.
