Im guessing your refering to the evaperater drain. Blow back up the drain tube with compressed air. Take the cabin filter out. Is it full of leaves and dirt ect...? If so this is what clogged the drain. The case will need to be cleaned otherwise will block up again. Replace the filter. Im guessing the original problem was the water on the floor of the car, right? Flooded evaperator.

It means that the tube is clogged. You need to clean it out or eventually you will have a leak of the water that is backing up in the system.
Remove one battery terminal and touch it to the other to discharge capacitors in the system. Reconnect the terminal and you are good to go. Don't forget to clean the terminal while you have it off.
Conditioner
It may be because the drain for the condensation line is blocked. Look under the car where the condensation water should be falling and see if it is draining properly. If not a simple clean out of that drain should fix the problem.
