Water leak in passenger side floor when air conditioner is operated. on 2000 Jeep Cherokee

Water is leaking into passenger side floor when air conditioner is operated. I think something that is supposed to let this water go out is plugged. Where is this and how do I access it and unplug it?

the water might be leaking from your heater core hoses. it is under the passenger side dash right against the firewall.
I'm new to this site and you're right. I had the same problem (suzuki xl7) and noticed a hose under the passenger had become loose. I easily put the hose back and haven't had the problem since. Now I have a ? for you. Do you know why the ac light would blink on and off?
I have a cadillac cts 2005 and I also have the same problem. I turn the a c on and it starts to leaking inside the passengers side. what can i do to stop it???
i heard that the drain plug was made up of two half circle like so ( ). When the two pieces were connected there was no adhesive used so it leaks through that hole. i am currently having the same problem and trying to figure it out.
