2005 Toyota Corolla leaky condensor flooding rear passenger

HI
here is the prob the ac like your home ac produces water. If you look where your ac lines go into the firewall into your dash. There is a box here heater box this box also houses the ac condensor at the bottom of this box is a hose going outside this is a drain for condensation this hose is plugged and will need to be unplugged so the water drains outside.

You can use air pressure to do this or a coat hanger
