Thanks medic had a mind fart there was thinking a water leak from rain didnt think about the ac drain. Look at the firewall behind the engine about half way down in the middle you will see a hose a or hole. That would be your ac drain if its a hose try milking it to see if water comes out. If its a hole use a metal coat hanger see if the drain leaks water. Also not all cars run the ac in defrost mode yours may or may not but not all cars do.
Please consider a to help us answer more questions.
