My 96 LX does that too. My moonroof doesn't work right...won't close all-the-way flush. I've been wondering if my car thinks the "open roof" is a "door ajar" ? It's unlikely, but it would sorta make sense. Anyway, good luck, and let me know!!!
I have the same "door ajar" issue with my 96. I removed both door jamb switched. Interior lights turned off (as the should) but the "door ajar" light stayed on. I guess I could take the bulb out but I'm weird about that kinda stuff. I like things to work.
