Fog lights only work during daytime?

I noticed with my car that my fog lights will only engage in the day, almost as if they are only functioning as DRL's. I still am not able to actually engage them on/off, but once I put the car in gear they will then automatically turn on.

Even though in the nighttime or when I have my headlights engaged, I will see the fog light symbol appear as if they were on, but they will not be. I would press the button to engage the fogs on/off, but nothing would happen, the symbol would just remain on. So, I'm not sure if it's a bad switch but everything else works with that button to control the lights, (for example bright, dim, etc.)

I hope I was able to explain as clearly as possible. Thanks for the assistance in advance.
