No air flow

Probably a mode controller (kind of a stepper motor that moves flaps around inside your dash's heat/AC system to direct airflow. Here's a diagram that should be like your car (or very similar, at least)...
The mode controllers themselves are the devices labeled 6, 7, 8 and 9. Look also at the linkages that they move (#4 and 5) to see if one of them might be loose, broken or otherwise messed up.
Or it's always possible that the fan blades (being plastic) have come loose from the motor shaft. If it was making "odd noises" before quitting altogether, this is a distinct possibility.
And finally, I've seen fans get so much debris sucked into them that they no longer move much air, though usually by then they're making some "unusual noises" as the fan attempts to grind a pound of (for example) pine needles to dust.

It's looking like the cabin filter is the problem child here. Problem being its a real **** to get too, especially being 6'3" 260lbs with linebacker shoulders, anything under dash on this car is tough to get too.. The gas pedal has to come out 1st, good luck getting to the top nuts. I'm gonna try something a tad bit unorthodox here. I'm duct taping the inlets on the firewall except for a small area i can hook a shop vac up to, then Opening one output grate inside at a time and blasting compressed air thru the grate while the shop vac is sucking out the inlet. I tried the compressed air on a couple output grates and it improved the air flow some. So hoping it will get better with the shop vac also. It's not a perfect solution but it may back blast the filter clean enough to work.

If it's really the cabin air filter, the problem should have developed over many months, and I'm not a bit sure that reverse air flow is likely to "fix anything" for more than a very short time.
Also, I know I swapped out the cabin air filter on my 2005 V50, and it was a trivial job (so easy I don't recall how I did it). I know I wasn't removing things like the accelerator pedal though... I'd suggest doing a search on that job online and seeing what's REALLY involved.

I have the same issue with no air coming out of the dash board vents; the defroster and lower vents work fine. I did replace the cabin filter last summer - not sure it installed completely, since it had to be slightly folded to fit in the duct (with the gas pedal removed). It would seem all of the vents would not work, not just the dash vents, if something were blocking the ducting at the cabin filter.
