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.

the grounds may be bad they are behind headlamps but more than likely it is the switch

did you check if power was reaching the socket? you will need a test light to check, I would by one, it will come in handy for years. see if power is at the socket, if so there is a bad ground, you need to verify that to not waste a lot of time guessing, if the turn signals work OK the ground is probably good and there well may be a problem but check power in the socket first.

SOURCE: no low beams bulbs are ok fuses look good

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.
