Inside lights on 2004 Montana are out

The third brake light at the top of the back door cracked, and it had rained alot here in Naples Fl, so I assumed that water got in there and shorted out the circuit, so I checked the fuse box to see if had blown a fuse, but I don't see a fuse listed for the inside lights. None of the inside lights work but the dash lights and head lights do.

Any ideas. Thanks in advance for any thoughts.

Have an owner's manual?

If you go to the fuse block picture, it tells you what each fuse feeds....

Have you tried a new bulb for the brake light?

Have you checked all your fuses with a test light?

Did the inside, or courtesy lights, go out the same time as the third brake light?

Have you checked the rocker switch in the over head console?

My lights where out inside once and once I RTFM I found out there was a switch up there that would turn them off no matter what.
