My fog lights no longer turn on when the switch is pressed. Does anyone
know how to fix them?

thanks

There are four things that could be causing this, listed in the order
of ease of repair/checking :
1) The fuse is blown
2) The bulbs are shot (unlikely for both bulbs to burn out at once)
3) The button is bad
4) Faulty wiring somewhere

So start by checking the fuse and making sure all visible connectors
are tight.

0) You are on "running" lights and not actual headlights. Fog lights won't
turn on unless the headlights are on. The running lights are just bright
enough that you could believe the headlights are on when they are really
not.

The fog lights also turn off when high beams are on I believe.

This isn't as unlikely as you might first believe. Both
bulbs have seen the same usage, and have approximately the
same lifespan. What often happens is that one burns out
and you don't notice because the other is still casting the
familiar light pattern. When the other goes, then you
notice that NOTHING happens when you push the switch.
