It's a little early for this to be happening to you, however the one thing that I've had to deal with is the rubber strip at the base of the windshield (on the outside). Mine is dryrotted and leaks down onto my feet when it rains. Watch out though, dealerships want a stupid amound of money to fix it, so be careful. I've not tried to fix mine, i have no carpet and no plugs so my water sits there and eventually drains out, so i didnt worry about it. However with a nice '99 Heeeezy (Jeep) you prob wanna fix it... lataaaaaaaaaa
what kind of top do you have on the Jeep? If you have a sunroof, check the drains. They run on both sides of the sunroof down the door jams and go out of the floor boards.
it could be a number of thing first your heater core might have busted or maybe its the rubber around the door when it rains but good luck with that
antifreeze (Water) pouring down the front of the engine is from the water pump.
the heater core has got a hole in it or your top has a hole init. If the water is green it is your heater core. if not it is your top.
water may be leaking in from firewall or windshield area and ending up on floor, has happened to about 4 j body's that i know of... floor drains may also be plugged...
The source of the water is probably from faulty or failed window seals surrounding your front & rear windsheilds.
Inside the front of the engine, driven by the timing belt.
I hav e the same problem
Open the hood, find the fan on the front of the engine, find the 4 bolts holding the fan on, this is the shaft of the water pump. Follow it back to the engine and the apparatus it goes into that is bolted to the front of the engine is the water pump.
Heater Core is the likely culprit
Check window and door seals, then check the climate control vent drain.
leave the ac off. U should probably check it at our local dodge workshop, to fix it :)
