_My trunk lid will not shut until I slam it shut like 15 times. What do you think is causing this to happen? I would really like to fix my trunk lid on my own to save some money and I just don't know how this is happening. My trunk lid went from shutting perfectly fine for not shouting at all now. Do you have any ideas as to what could be going wrong to wear my trunk lid does not shut properly anymore. I have a subwoofer in the trunk that does a little bit of rattling but I don't think that has anything to do with it.
