Explorer dome light won't turn off

I've got a 98 Ford Explorer and the dome light won't turn off (and
neither will the light in the back.)

Well, it'll turn off if I remove the fuse that powers the battery
saver, and it'll turn off if I remove the battery safer relay, but
other than that, it won't turn off.

I replaced the relay, but it made no difference.

Any thoughts on what else I should check?
