Look under the dash on the passenger side and verify that it hasn't sucked a plastic bag or anything like that into the air intake. If you happen to have a dog that rides in the car, it can suck the hair in and plug up the holes in the evaporator not letting any air through it.
This is all assuming you haven't had any recent repairs to the AC system.
