Now, you need to turn the vents down to create a gap on top. Gently push the top plastic tab to the right while pulling the vent down and you should create a gap as seen here.

Shine the light into this gap and you will see two "hooks" on each side of the vents... You will need to use the thin screwdriver to pull these down. They have teeth to hold them in place; pulling them down is a bit tricky so be sure not to damage the teeth.
