1994 nissan altima GXE 10amp meter fuse blows with no regularity. Sometimes will not blow for a month other times will blow 3 or4 times a day

What system is the fuse blowing. There is a short in your system that is causing feedback into the system. For example:

1. A coin in a cigarette lighter will take out the Horn and Cruise control
2. Winding in the Fan Motor will short out as the hit bumps and short across multiple power sources
