Gauges fuse blows frequently

I have a Buick Century 1991, 3.1 engine, which is blowing the gauges fuse several time during a month. Anyone have had this situation or have a suggestion to solve it?

Install fuse, and then start moving/pulling fuses until it blows...

If it doesn't, you will need a schematic, to find out how many circuits that fuse feeds....then isolate them one at a time....
