If I remember correctly, when you have the hood open and you are looking at the engine, there should be a black box to your right that contains the relays. Either on top or inside the cover should be diagram that denotes the relay positions.
Open the box, find the headlight/dashlight (if they are the same) relay and pull it out. It my be tough, wiggle it carefully while pulling up and it should come out. Check to make sure that all the connections on the relay and in the relay box are clean. If not, get some contact cleaner and apply. I like to install and remove the relay a few times while the cleaner is applied to scrub away any deposits.
Then reinstall the relay. Get someone to turn on and off the headlights (with the ignition on) and see if you hear any clicking. The relay should click on and off as the switch is turned on and off. If not, then some additional diagnostics is necessary.
As I see it, the relay itself, the ground circuit, light switch on the column or the signal wire to the relay could be the problems. While this may seem like a huge thing, with a little testing here and there, we should be able to get you up in no time.
When I get home from work tonight, I will check my Accent to see where the relays are located as well as where to check with a voltmeter to help you in your diagnostics.

Thanks alot, they're in the same box as the under-hood fuses are. I don't know what a bad one looks like though. But yeah.
