It is coming from the air conditioner up under the dash board and running under the carpet. I pulled the seats out and lifted the carpet back on the passenger side today and vaccuumed out about 8 gallons of water. I watched the sponge under the dash/forewall pad drip with the A/C on and stop with it off. Car does not leave a puddle underneath (outside) when A/C has been on like most cars. Is there a drain hose somewhere that may have come loose? I need to stop this so I do not rust the floor out.

This is a common problem this time of year. You will need to get under the vehicle and look for a short plastic tube coming from the black case at the firewall on the passenger side. Carefully insert a piece of wire up it about 2-5 inches. Most likely you will get a rush of water so you might get wet. If you have a shop you regularly get service done at I'm sure they will clear it inexpensively if not for free.
Thanks much. This put me on the right track. There was no clog or rush of water. There is only a short nipple protruding through the firewall into the engine compartment. Water is running out of it and back through the firewall to the inside through the foam insulation. It looks like there should be a plastic or rubber hose hooked to the nipple and down past the frame rails. I put a piece of garden hose on it for now, and it appears to have fixed the problem. I will know in a few days when the carpet and foam dries out. I will stop at a salvege yard and look for a similar vehicle to see if there is something missing.
