Top comes out on the roof:
Not sure what happens below. Haven’t gone under the house to inspect. Seems like a vent that travels through the wall space, but unclear why it would do that.
Any ideas what its purpose is?

Vents are designed to be venting, and that airflow is enough to keep moisture levels down. Stop the ventilation, and it just becomes a covered hole in the roof.
