Hello I have a 1984 Chevy k5 blazer and my friend fried The two dome lights one in the camper and the other in the cab I replaced the light bulbs and the lights still doesn't turn on so I'm guessing that it is the fuse does anyone know what fuse it is that needs to be replaced and where it is located? A diagram would be nice. Thanks guys

 

fuse panel should be under the drivers side dash board. Usually there is a diagram associated with this in the owners manual that should give you all the info needed.
If you do not have the owners manual, google "1984 k5 blazer fuse diagram"
