Theres more than 1 interior light fuse. The main one is under the hood fuse box number 31 or 34. This one also control the parking lights (first click on the light switch). If your parking lights works, then theres another interior light fuse at the passenger side fuse panel. Check those fuses, it won't say interior lights, its tied into something else. Look for a blown fuse there. If they're all good, then its prolly a bad switch or wiring somewhere.

I'd start w/ that.
