Do my car's dashboard lights need to be replaced?

I drive a 2002 Ford Taurus, and my dashboard gauge lights have not been working for the past few months. I turn on my headlights. And the turn signals light up, as well as my brights signal when I turn them on (in photo), and the turn signals work when I use them, but the speedometer, fuel gauge and all other gauges won't light up. When I turn the ignition to the two position all my dashboard warning lights come on too. I've looked at my fuse boxes (both of them) and nothing. Do I need to replace the dashboard lights? And if so, how do I get into the dashboard and replace them? Any help is appreciated!
