I would look at the switch for the hazards, possibly fit another switch?
Fog light, the switch has 2 setting, 1st click is front fog lights (if you have them but not many cars ever did) 2nd click is rear fog light and the headlights have to be on main beam for the fog light to work. May be something simple as switch not in the right position?
