Works, then doesn't work, then works

This title is in regard to my interior lights and radio. Everything use to work from this fuse luggage light, interior lights when doors are open, radio, clock and glove compartment light.

First the luggage light went out, I just thought it was a burnt out bulb and left it that way. Then the interior lights wouldn't work nor would the radio. The clock and glove compartment light both work fine. Then after about a month the interior lights and the radio both started working again. Now about a month later the interior lights and the radio both stopped working, but the clock and the glove compartment light both work fine.

I changed the fuse even though the old one looked fine, but it made no difference.
The interior lights and the radio both don't work. Does anyone have any suggestions?
Thanks

The interior lights and radio come off the bottom of fusebox 1 fuse 1. Did you check to see that that wire is fully engaged and tight into the fuse holder? It should be a small-ish black wire.

/\ this plus check the ground wire connections.
