Quite possibly, the 'open' limit switch is not making contact (which I believe tells the system the 'path' for closing is active). I have not looked up the schematic, it is an educated guess. Download the service manual in the documents section (free). Look for something limiting the spoiler travel when it is up, maybe a part of something is blocking the spoiler from fully opening which results in the limit switch not making contact. Good luck!
