Hyundai Repair: Headlights, hyundia sonata, beam headlights

Question
I have a 2002 Hyundia Sonata, all of a sudden my low beam headlights will not come on. The high beams,parking,fog and blinkers all work fine. I checked the bulbs and the fuse,all good. I am lost here.

Answer
It is not uncommon to have bulbs that "look" good and are not. Test the bulb circuit at the socket with a test light or a known good bulb. The next thing is that if your car has less that 60000 miles the problem may be covered under the factory warranty. Head lamp and fog lamp bulbs carry a 5 year 60000 warr. so would the related switches and relays.
Contact me if you have no power at the sockets and I'll pull up the wiring diagram and see where to go from there.
