Corolla - Fuse Problem

[rokit88]

Hi, new to the board... here's the problem:

I've got a 97 Corolla and the other night I noticed that all my instrument panel/dash lights were out. Ok, sure enough the fuse is blown, and I replace it (it's a 15A fuse). The next night, I drive a bit and then the lights go out again and I replaced the fuse again. So basically when I replace the fuse, it blows out right away.

Is this the sign of a short somewhere? Is there anything else I can check or do? Do I need to go into the shop/dealer? Any help is much appreciated!

Thanks!
