Hello everyone. We have a 2000 tow lite 17 ft. There are 2 interior lights on the wall in front that do not work. Everything else works ok. We have checked fuses, and all things. Only thing we can figure is they have somehow become separated from their power system. Cant tell where the source might be coming from. Overhead bins above them do not have any of the wires from interior, only the running yellow lights. Any help or suggestions would be appreciated, as don't want to tear walls apart just for these two. Thanks
