I don't know if this true for a Toyota, but my Ford had the same problem. Which is the area in front of the windshield, where the air comes into the car and the A C use the same drain. This drain can some time get plugged up. I was lucky just forced alot of water down the front grill area which cleaned out the drain line. If this doesn't work, I don't have a Toyota repair manual yet, you may have to remove the inside fender well cover and get to the line to clean it out. Since I have a new Toyota pick-up I would be interested to know if this helped with your problem.
