I don’t even know where to start on this one. My Marquis has the kitchen/sofa slide out on the driver side. There are under cabinet lights above the sofa and above the sink. There is also a rope light tucked up behind the slide trim at the ceiling. These lights are dead. Have all worked in the past. The only other 12 volt load on the slide is the shade motorS, which are working, and the storage bay lights, which are working. Everything on the 12V breaker panel is in order. Any ideas?
