Hi, I have a 08 Accent Hatchback. The trunk door knob(the black plastic hinge thing which you pull to open the trunk, not sure if I call it right) does not reset. I mean after pulling it to open the trunk, it's stuck instead of going back. I need to press it to original position, so the trunk door can be locked. I can see a rusty spring behind the black piece of plastic. Not sure where is the problem(maybe the spring?). How can I fix it. Please give some step-by-step instructions. Thanks a lot.
