I agree that you most likely have a clogged AC microfilter. Its located in the front of the heater case. You must remove the glovebox to access it. Its a medium skill level job. I did a quick google search and came up with this for you. It has instructions and a picture.
Yay, that was definately the problem for not having hardly any air coming through the vents.
That vent was caked upon caked of dirt/dust, i don't think it ever was changed. Now it blows really well.
Now another question. Does this car have a climate control where it slows how powerful the cold is of the ac when you slow down? Also it doesn't get that cold when i get moving on the road, are these cars known for weak ac strenght?
before you replace anything have the system checked to see if it needs refridgerant. If it is full and still doesnt blow well then you would want to check the system pressure for clues as to what the failing component is rather than just guessing.
