SOURCE: leak onto floor passenger side from neck of ac drain through firewall
It's not your heater core. If your heater core is out it would leak antifreeze. My wife's 97 Grand Cherokee had the same problem. It is condensation from your AC coming leaking through a round hole in the AC unit at the firewall. Pull the carpet back and dry out underneath it, there will be a lot of water and we had to leave the carpet pulled back with a fan blowing on it all weekend to dry out. I fixed this about 8 years ago so if I remember correctly, the was a plastic part of the AC at the firewall that had a hole in it that the water was coming out of, I could see leaves and debris in the hole so I know it was part of the drain system. I cleaned out what debris I could and used a cone shaped peice of rubber and twisted it in to plug the hole and tapped over the plug to ensure that it wouldn't back out with vibrations, etc. After you dry everything off start the engine and turn the AC on max, you'll be able to see the where the water is leaking from after the AC gets cold. Hope this helps, it drove us nuts for a year before we figured it out and the wet carpet smell wasn't pleasant.
SOURCE: i have transmission fluid leaking
Hmmmm, The tube running to the firewall may just be an elevated vent for the trans, but it should noyt vent into the passenger compartment. Are you sure it isn't brake fluid? Brake fluid is used for the clutch as well as brakes. if either brake or clutch cylinders leak it would or could be possible the fluid will enter through the firewall and run down the nearest thing.. Ck that out, you can tell by smell which it is. brake fluid will wash off with water, gear oil will not. good luck

IT WORKS LIKE A LOOP YOUR HEATER CORE ACTS LIKE A U-TURN SO IF GET A U-SHAPE PIPE AND CUT THE HOSE TO FIT IT WILL SOLVE YOUR PROBLEM
SOURCE: COOLANT LEAK CANT FIND
Sounds like your heater hose leaking or your heater core leaking. The heater core is in the firewall and the hoses leading to it can be inspected from the outside under the hood. Worse case scenerio would be the intake manifold gasket leak, but that is usually accompanied by irratic idling. I would say the heater core though or hoses. Hope this is helpful to you
