if the garge has a gas appliance (water heater or furnace for example), a wall vent may be required for combustion air for the appliance. the screen would be to keep animals or large insects out. if this is the purpose of the vents, closing them will result in us reading about you in the obituaries! if no appliances are in the garage, they may be used as a safety vent for vehicles running in the garage- great idea!

Greetings;
I have been a home designer for most of my life, and
I have never heard of such venting, as standard practice.
I would assume that it would be there mainly for reducing
interior humidity and condensation, rather than for venting
exhaust fumes. But, some garages, just as many barns
do, have vented cupolas up on their roofs. Most older
garages have been built without a poly vapor barrier under
the slab, so moisture rises through them, from the ground,
and of course, cars can carry in snow and other forms of
moisture. However, a slab, over dry ground (or gravel fill)
with poly VB should not require the garage to be vented,
any more than natural leaks, and occasional door opening.
