ongoing issue : illumination lights non op

Hey guys,

i been having a problem with my illumination (dash lights) not working at all. Everytime i put a new fuse in, in a matter of minutes, hours, or days the thing will blow. I 'm thinking it's the dimmer switch so i go to the wreakers and re and re it and boom does the same thing, i'm thinking maybe coincidence so i got another one and does the same thing so i'm cuttin the dimmer switch out of the calculation. What other things can i go by to fix this big problem. the fuse position is 13 i believe it was with a 5 amp fuse.
i got a 89 mustang 5.0

sounds like a classic case of a bare wire touching a metal surface. #13 should be a 5 amp fuse, so check the wiring between the switch and the fuse box.
