2001 Honda Accord

All the gauges on my 2001 Accord stopped working. At first they would work intermittently, but now they don't work at all. The tach and speedo read "0", the fuel reads "E", etc. What could be the problem? I was thinking it was a fuse, since they all stopped working at once, but the fact that they once worked intermittently has me questioning that idea. Anyways, I still tried to replace the fuse, but I could not find it. I looked on the driver and passenger side and the box under the hood. The closet thing I could find was gauge lights, but I wasn't sure if that was the same thing. TIA.
