There are no interior lights in my 2001 Buick LeSabre. What could this be if it

What is your question?

None of the interior lights work so I doubt it's the bulbs. I tried replacing the fuse and that didn't work. DO I have to take off the entire dash to check the switch?

What makes this problem better or worse?

Nothing

How long has your 2001 Buick LeSabre had this problem?

Since I got it 2 weeks ago
