Hmm... Make sure the clips are sitting flush and does not stick up. Or you could take the clips out again, give them a clean if they are dirty. Mine were a bit dirty and didn't fit in properly, so I washed them and they fit like new.
**Make sure that the handle/lever is on top of the plastic trim... and not under it. The lever must be "threaded" through the hole.
If it still doesn't work, try slamming the hood down a bit harder than usual. Good luck.
