Yea, if the top won't move either, then I'd say the trunk lid is not indicating that it is closed.

I have TRIED to figure out where that sensor is - Ala_x, can you point in the manual to where it is? That is the one sensor I've never been able to find.

Also, downloading and printing the specific pages in the manual will help you figure this out. But again, if neither the top or spoiler will move, the most likely common denominator is the sensor that indicates the trunk is closed.
