well sense no one else jump on this, it your talking about the dome light, it will go out even if the door is not fully latched, but there is no lights saying, "door ajar" or anything like on some cars... and if your dome light is not coming on when the door is opened, then check and make sure your dome light is set to "door", check your bulb, and then if that doesn't work you got bigger issues. there is no easy switch to replace, your gotta replace the whole door latch if i'm not mistaking.
