I have posted a few times before that the passenger side floor gets wet on my 97 TJ while sitting.
I have had several suggestions that my air duct infront of the windshields drain wasn't working. I have checked it a few times and the air duct isn't hold water, and the drain seems to work fine. I have also tried the water hose into the vent and didn't see water leak in.

What else can it be ??

How bout the door? Get in there and have the wife give it a going over with the hose.. While you watch from inside.
Are you still sure it is not the heater core?

Check the gasket that seals the surfaces where the windshield folds.

Big jim,

I checked the taste of the water on the carpet and didnt taste any anti-freeze so i don't think its from the heater.

I used the hose around the door, and some around the windshield hinge/seal. We see the dripping from below the dash, and I dont see many places for it to come from. At first I thought maybe it was from the AC, but we now notice the wet floor after the Jeep has been sitting, like over night or at work all day after a heavy rain. I just changed unsuccessfully to the soft top thinking maybe it was the seal around the top of the windshield.

Could the water be slowly working its way through the air duct through the heater and I didn't notice when I flooded the outside air intake?

You guys have been great in diagnosing many of my jeep problems, as always, open to try most anything.

Ok then do THIS! Getcha a big piece of cardboard and put it ABOVE the floor for the night! Fill the passanger floor area with it.. Then the next morning look at where it has the drips..

Doug,

I'm not that familiar with the TJ system, but the system on my CJ-7 actually has two drains. There is a large drain for the intake plenum in the cowl area. This is the one that most people have been talking about. However, there is another drain for condensation and slow leaks in the heater coil. On my Jeep, that drain is just below the motor coming out of the lower part of the firewall on the passenger side. There is a metal drain tube coming out of the heater assembly under the motor and going forward through the firewall. On the engine side of the firewall, there is a short drain hose attached to the drain tube with a radiator hose clamp. That drain hose hasa 90-degreee bend in it, and the total length can't be more than 4-5 inches. If you do a lot of off-roading in mud or dusty dirt roads, that drain hose can clog up with dirt. It that drain stops up, then water will back up into the fresh air outlet under the dash and leak onto the passenger floorboard.

Hope this helps....

What he just stated is a fact, and also if the heatercore is leaking you can turn the heat on, you will either smell it or the windsheild will get residue on it.
