I have a 1993 Cadillac STS and in the the fuse panel in the trunk it says there is a 10 amp fuse that controls the 'rear fog' and the probably isn't that it pops fuses or anything. The fuse insert isn't even there. Like, the 2 metal prongs that the fuse goes between don't exist, but on the fuse panel cover it shows that there is a fuse that belongs there. Can anyone help? [My rear fog lamp isn't on either, so I know a fuse belongs there.]
