Anyone know which relay under the hood would work the interior lights. They were working, then ...... I checked the fuses and nothing is blown out so I'm hoping on the relay. I don''t have the owners manual.:

I don’t have a Catera, but my Deville lists what each fuse and relay is for on the back of the fuse cover. I had to remove the whole big fuse cover (not just the little one) to see the label on the underside regarding the relays.

Relay is under the left knee bolster, 2 large 1/4 turn screws release panel. Probably a headlight switch though. I forget if that relay is labelled as such but some of the relays can be swapped around to test

type in catera user manaual (correct year) in google.
