Why won't my interior lights go out? on 1992 Buick Park Avenue

I came out to my buick to find out that the battery had been drained. After jumping it, I noticed that the interior lights would not go out. I pulled the fuse for the interior lights, but it still drained my battery. The only way to keep it from not being drained is to disconnect the battery.
