A/c cools good but blows very little air even in top speed
Ac blows very little air on 2002 Chevrolet Cavalier
Check air return under passenger side of dash, it could have sucked up a plastic bag or other trash. If not that in all likelihood the cabin air filter

To solve this you have to take it to a AC Service Shop. It has the Evaporater clogged. It needs to be cleaned. By time to time it takes in all the dirt of the rug and the opening and closing the doors just adds to it. They will check the fan motor first but usually its just clogged.To clean it, they will have to take it out,save the Freon for it to be used again etc. to do a good job.I'll bet my bottom dollar since I'm a Certified AC Tech.
