2006 Sonata, first the low beam head lights went out but still had high beam and fog lights, did not fix, then a month later the dash lights went out but fog lights still worked, the next day no lights at all including dash????????

Hyundai puts the fog lights under the rh or lh tail light fuses but it does not tell you that in any documentation. Also commonly the gliove box and smoe dash lights on that tail fuse as well.

This sounds very suspicious it is possible all the light just brunt out BUT very unlikely check fuses and test lights if lights or fuses are bad ? then test alternator volt regulator that it is not putting out too much volts not over 15v if that is OK then their is A short ! fore short you will need A weiring schematic PS. let us know please.
