Hi there!

You would be doing yourself a disservice by trying to diagnose this without a wiring diagram. Most of your service manuals will have them in the back. With it, you can tell what components are protected by the fuse you mentioned. It appears that the fuse you are speaking of could be the MAIN fuse?
Keep in mind that fuses blow when the protected circuit draws more amperage than the fuse is rated for. Typically we are looking at a component on the circuit being bad (like an electric motor) or two circuits somehow crossing and pulling power through one source. With a diagram and voltmeter, you should be able to narrow it down pretty well. - This can be time consuming, however, and their are cases when paying a professional to fix it far outweighs the cost of your time and frustration. :)
