Jeffrey,
If you are confident that both headlights are good, then my suggestion is to first investigate whether your fuse to the lights is blown.
To locate the fuse box, consult the owner's manual. But I believe you'll find it if you look under the dash on the driver's side. It is either on the left side of the driver's footwell in a side panel, or it is up under the steering column. Consult the owner's manual to find it.
Pop the fuse door off and look inside the door for the layout of the fuses and what electrical items they connect to. Your owner's manual may also have the layout picture of the fuses. You should see a fuse for the headlights. You'll need to pull that fuse and inspect it. The box cover may have a plastic fuse puller (which looks like large flat tweezers) so use it to grab the headlight fuse and pop it from its socket. If no fuse puller is in the box, then use a pair of needle nose pliers to carefully pull the fuse.
Once you have it out, hold it up to the light and see if the metal link inside the plastic portion (just above the two flat blades) is broken or "blown"). If it is, then that's your problem and you simply need to replace that fuse with an exact one that has the same amperage rating. The amperage rating is a number stamped into the top of the plastic fuse (e.g. 10, 25, 30, etc). Sometimes the fuse box has a extra fuse of that color and amperage, so check it before heading to the store.
If the metal link looks solid and unbroken, then take a emory board (that the ladies use to file their nails) and draw it across those flat blades to remove any oxide. This ensures the flat blades make solid contact with the fuse socket when you re-insert it.
Check the lights after inserting the new fuse, or the original good fuse.
If the lights still do not work, then I'd look to this next step:
Check the wire sockets going directly into the two headlights to be sure they are well-seated into the back of the lamps.
If that doesn't remedy the issue, then you are likely looking at a bad dash switch. Before you pull the current dash switch, give it a vigorous on/off cycle a few times in case it has some oxide on the contacts inside. Also check it's wiring socket on tha backside of the swith to ensure it is well-seated. That can be a pain to get to, tho. Hope this helps. - RedRanger
