pull the fuse..as someone wrote > It'* not often a problem with your year. I have had numerous problems with the headlight/twilight switch. Replaced it once in the '96 and twice in the '95. pita. There was something about the switch-load which made them fry and it would present itself as any different type of problem with headlights, inside lights.. they wouldn't come on or wouldn't go off. I finally declared it a "feature", The work around both times was to skip using the headlight pull out **** and go to just a tad of "twilight". Just unclick it clockwise and leave it at the first mark. You'll never have to touch it again. Another approach if headlights or inner lights won't go off is to just move the twilight switch as I said, then click it back. Sometimes that clears the light cycle too. And honest to gosh, ocassionally the inner lights just won't go off because they feel like it. But then will clear after 15 minutes, there is supposed to be a light sweep at about that point in time to keep ya from suckin' the battery dry.
