Check 5 and 13 inside the car.
Check the underhood 50 amp fuse for the exterior lights and gauge lights (IIRC, there's only one fuse under the hood for these circuits).
Do you have front marker lights? If not, take a look at your headlight switch itself and it's connector. The marker and instrument outputs might have issues. The connectors have been known to melt.
WHile in there, check outputs for each. If you have them, move downstream.
More info about your car's issue will yield more precise info.
Good luck.
