My 2008 Grand Prix trunk latch just stopped latching today. It seems like everything works properly and is secure, so I can't figure out why it wont lock. If I stick a screwdriver through the latch (mimicking the loop on the car), the latch itself locks and unlocks properly. The latch does not seem loose or out of place, nor does the loop, and the trunk door goes down as far as it can. The hinges seem secure too. I just can't figure out why it wont latch when the door is closed. Did anybody figure anything out?
