Answer
Jane,

There is a drain for the condensation to drip onto the ground.  This is a rubber hose that is connected to the heater box and it goes through the floorpan to the ground.  If the hose is blocked water will backup into the box and overflow inside the passenger side of the vehicle.  Have someone jack up the car and get under the passenger side and look for the small rubber hose that comes out of the firewall.  They will need to unplug the hose.  Probably dirt or a wasp nest has clogged the hose.
