Map Light Switches Not Working

[TX900s]

When I open my door the front map lights work, but when I'm in the truck the buttons in the front for each map light don't seem to work, in the front and rear. Is there a separate fuse or relay for these lights or switches?

I know the GMT800's (or at least, the later ones, like my '04 Sierra) have two separate circuits for the map lights, one from the bcm, and one going through the manual switch near each dome light.

Sorry I didn't identify my truck. It is an 2007 Sierra 1500 classic, old style.

After much search, I found which fuse it was. It is fuse TBC2C on the fuse panel in the cab at the end of the dash. That fuse runs the map and dome light buttons on the lights and the cargo light outside.
