Gauges

[Zig]

I have a 95 Blazer that developed a short in the gauge cluster. (Fuse for gauges keeps blowing.) I was just wondering if there is a common problem? There has never been anything done with this other than a new engine put in. The dash has never been opened, so I'm wondering how the ---- a short could develope? Ideas? Things to check? Thanks for any ideas!

check the windowsheid for leaks around the cluster or the Printed Circuit board has got burned some where, Corrosion on the board, dust shorting it.
could be a bad peanut bulb.
