Question about 2006 Hyundai Accent
SOURCE: no high-beam headlights
It may not be the switch; most hi-lo changes are via relay to prevent the higher currents from flowing through light-duty switches.
Locate the relay cluster (it might be near or with the fuses) and if they aren't marked, pull wach one of them and plug back in several times to wipe possible corrosion from the blade contacts.
If they are marked, look to see if the same relay is used elsewhere (part number should be visible) and swap them temporarily to see if the relay is at fault.
Some vehicles will use separate relays for hi-lo beams and another for flashing since that often turns on both beams momentarily.

There's only one relay, but two fuses, both located in the underhood fuse/relay box.
Sounds like you have a wiring problem since sometime the left works and the right doesn't, then the right works then the left doesn't. Might be the multi-function switch on the steering column in combination with the connector M10-1, EM01, SE14 & 16.

SOURCE: high-low beams not working
Check for headlight relay and fuse. Some cars have separate circuits for head light flasher and normal high/low beam. From your description, I would suspect a bad connection to/from relay or relay itself.

On the 03 Accent, there is only one relay which supplies power to both circuits. The 'distribution' of power is controled by the multi-function switch (turn signal switch).
As you can see in this wiring schematic/diagram.

There may be a relay that operates the low beam lights, check the owners manual to see if there is a relay, you should be able to hear it go "click" if there is one.
