Some weird problems with my 2001 Bonneville that all started happening at once:

My sun-visor lights do not turn on at all. My interior lights (front and back seats) do not turn on when the buttons are pressed, but they do turn on when the doors are opened (sometimes!) or the driver'* **** is turned (always).

And to top it off, the 12v "cigarette lighter" in the ceiling does not work. (The others do.)

-What fuse is for the sun visors? I don't see that labeled.
-Is there something that would affect all of these issues?

I have checked the fuse for Interior lights, it is good. I have swapped the relay for the Interior lights and it still does the same thing.

I don't want to take it in for something that seems as simple as a fuse or a relay!

Thanks!

It looks like I want to take a look at splice S329 and Ground G404. It sounds like S329 should be under the back seat somewhere, and G404 should be in the trunk somewhere. Can anyone help me as exactly where I should be looking? Thanks!!
