Just reading the posts about phantom leaks---my dad had a similar situation once on his car. Everything off, car sets for a few days--battery dead. Hunted down everything we could think of, to no avail. Happened to walk by the car one night & noticed a dim glow in the dash. Lo and behold, the dang glovebox door was not shutting all the way and the light was on. We never saw it in the daylight, but at night there it was. Fixed the glovebox door and solved the problem. Just saying. .. .
