88 Accord Lx lights won't turn off.

I have a 4d 88 accord lx that I can't turn the lights off. The switch rotates, but nothing happens. I have to pull the negative lead from the battery to kill everything. I have removed the combination switch, trying to read the contacs, but it seems that have no continuity anywhere. Am I on the right track, or could there be a relay that has cooked itself closed?
