Ceiling/Porch Switch Doesn't Work - 1999 Winnebago Itasca
(Hanford, Ca USA)
The light switch that turns on the ceiling light and the porch light doesn't work and also one of the switches that turns on the floor lights in the hallway doesn't work.
I'm thinking it may be a fuse but I don't know where to look. I tested the wires and it shows no electricity.
