heater fan broken.
Yes, gnats can come out of dirty air vents. Gnats can actually come from anywhere. They are very pesky creatures.
The heater may not be on - but the fan still blows air through the vents when they're open !
the middle vents only supply air from the ac unit using a separate in dash fan. the floor and defrost vents come only from the heater
something has to be blocking the vents.
leaking ducts allowing air into system.
Return air vents.........
I just had that problem with my 99 Monte Carlo. When I accelerated or went uphill No air would come out of the dash vents. Problem was a Vacuum hose. Cost about $40 to fix.
The heater blower may not be working properly. Without the heater blower working, the air will not come through the vents.
The magma gushes out and then it flows every where. The volcano has vents that let air come out. When the vents open steam/ smoke comes out of those vents.

I am sorry, I am not technical on this stuff, but we had the same problem on our 95 Mustang GT. We had to take it into the dealer and the problem was that one of the hoses had come loose, so it was not blowing enough air pressure to force the vents open.
Does air come out at defrost vents? Defrost is the default position. Check for a vacuum leak either under the hood or under the dash Check the operation of the vacuum actuated motors under the dash Check the operation of the selector switch
