Just what the title says. I unfortunately don't know where the fuse box is and I can't seem to locate it. The gas gauge, temperature gauge, and power windows have stopped working (I assume this is due to a blown fuse).

Could someone please tell me where I can find the fuse box, or if this problem could be for a reason other than a blown fuse, tell me what it is? If it's just a blown fuse as I assume it is, I'd much rather do it myself than take it to a mechanic. But if it's something more technical than that, I might need to. Is there anything else this could be other than a blown fuse?
