Have you checked the fusebox for corrosion?

Hi Patrick, and welcome. I moved your thread to the electrical section because you should get more useful help here.

I'm sure the fog lights are on a separate fuse. Do the turn signals and parking lights work? I wonder if the headlights and fog lights might share a common ground? That connection could be faulty too.

My suggestion is that you actual do some diagnostic work instead of just guessing and replacing parts.

Do you have a multimeter and do you know how to use it? If the answer is "no", then take it to a shop where someone who knows what they are doing can do the work.
