Courtesy lights inop.

I bought a real nice 94 GTP about 6 mos. ago and the interior lights didn't work. I found a blown fuse and replaced it and it worked fine for a while. It would blow every 4-8 weeks and now it blows the fuse when I try to install a new one. I thought I would try here before I took it into the shop as I'm not an expert on wiring. Any help would be greatly appreciated.

My first guess would be a that you have a short in the wire.
