Long time lurker, first time poster. I have two lights on the coach I can't get working -- the light over the entry steps and it's match on the left rear of the coach (above the water and sewer hookup bay). I finally managed to get one of them opened and replaced the bulb but it still didn't work. The illuminated grab bar and the lights under the stairs come on when the porch light switch, but not the porch light or the one on the other side of the coach. I checked all the breakers, but they're fine. Am I missing something? Have I missed a switch. I'm not the first owner of the coach, so don't know the history. Thanks.
