There is a vent in the middle front dashboard by the windshield. Mine is cracked and breaking apart. I did a Google search and it looks like that vent is built into the whole big plastic piece, so I can't buy the vent separately. Has anyone found an aftermarket solution to the broken vent? If not, has anyone replaced this whole plastic piece? The replacement piece isn't terribly expensive but I wonder if it's something my husband can snap in, or whether it requires special tools.
