The fuse block is located on the bottom of the dash to the right of the steering column. The fuses are marked as to what they are for, although some cover more items than listed in the small space next to the fuse. According to my Chilton manual the dome light as well as the cigar lighter, glove box light and others are on the same 20 amp fuse. The manual shows a layout of the fuse block, there is no way I can post that here.
The simplest way to find the right fuse might be to simply pull out each of the yellow 20 amp fuses, one at a time, until you find the blown fuse.
There is a release on the end of the fuse block that allows it to swing down for easier viewing.
