Radio and cigarette lighter fuses
I have a 2003 Winnebago Adventurer. Note to let others know. I replaced my dash radio and after the installation I noticed the cigarette lighter did not work. The radio did not work as well when I switched over to house batteries. I checked the fuse box under the dash and both fuses tested ok. After further testing I located another fuse that solved the problem. I have two fuse boxes under the dash on the driver side. The other fuse I mentioned was in the second box just above the larger box with my radio and cigarette lighter fuses. It was a 20 amp fuse and after replacing it, the problem was solved and both cigarette lighter and dash radio now work.
