You probably have a short to ground in the wiring between the fuse and the dash. I think in your vehicle the dashlights and the running lights run off the same fuse buy I'm not sure from the wiring diagrams I have. You have to look for damaged wiring or a problem in a connector somewhere. See if the running lights are out, too. If not, then the systems run off different fuses.
You may want to look up an auto electrical shop if you have no luck.
