My trunk keeps opening and killing my battery could it be a fuse, i have a 2006 pt

bad trunk latch or release

I don't know what's causing it, but I have the SAME in my 2005. I took the light bulb out from the overhead and stopped the battery leakage. After a few months, I put the light bulb back and it worked for another several months. Yesterday it happened again, so I took the bulb out again. I don't think it's a fuse because, I'm a chick and don't know a lot about cars, but I think a fuse either works or it doesn't, it isn't intermittent. If anyone knows the answer to this puzzle, please advise!
