Here's the part that I am trying to describe: https://drive.google.com/file/d/1C0ENDk_zll0cBa9aoRKwI5QgCKMQRRuB/view?usp=sharing
Why I would like to cover this up is because my car is parked outside and there's small leaves coming through this part of the car. Then when I turn on the blower, it spits out leaves.
I would like to cover it with finer mesh to prevent small leaves from coming through my fans.
I think what I need to ask is, what is the purpose of that vent. Can I cover it up completely? If I can't cover it up completely, what can I use to cover it up just to prevent small leaves from coming in.
