1992 honda accord lx a/c problem

a week ago, the a/c in my manual accord with 175,000 miles stopped working. after a couple of hours, it began to work fine, and then stopped for good. no air at all is blowing, regardless of whether the a/c itself is turned on or off. both of the fans function when the air is turned on, but nothing makes it into the car.

i checked all of the fuses, and they are fine. the a/c was recharged and a new fan installed 2 months ago.

also, i dont know if this is relevant, but it was a rainy day when the air/ac stopped working.

any help will be much appreciated.
