Interior running lights do not work. There is no apparent fuse to place for this problem. The lights were working and then not sure what changed but they don't work anymore inside.

Possibly the *dome light* override switch is activated (set to off) .. If not - then it's still possible (more than likely) a blown fuse. Testing IS required!
