You should never use high beams when you are driving in fog because they shine up and ahead which will be reflected straight back into your eyes by the fog. Low beams (which aim downwards) and front fog lights (which are lower) are far better suited.
Actually, in most states it's against the law to do that. That's if you get caught doing it though.

Not true. Hi beam lights shine higher above the ground. They will reflect back at you from fog and make it harder to see. Low beams shine lower and are not reflected back at you.

Fog is a colloid which disperses light that shines through it. Because high beams shine straight ahead and further down the road more of the light is able to be scattered and reflected back towards the driver.
Your high beams work but your low beams do not because the switch is broken that switches between high and low beams. Electrical switches wear out.
