The hatch cover edges don't seal, so they drop down when you step on them, and the whole hatch vibrates like mad. What can be done to fix this? Thanks!
I would first look at the hinges and make sure the bolts at the hinges are not loose. See if the gasket on the hatch lid needs to be replaced. That would help with it vibrating and would get it a better seal. Could you send a picture please?
