Light problem

[E3Y]

When I got into my car after getting to the store, I turn on my light and there was a slight problem. I realized that when I'm turning to the first notch, halfway thru the light for the gauges comes on, but once you get to the first notch, no interior lights. But once you get to the second notch, the headlights pops up, but no interior light. Turning it back one notch, headlights come down instead of two notch back. I drive a firebird 2002. Does anyone know the problem? I also check the fuse and nothing is wrong.

I would replace the switch
