99 Wrangler Water Leak.

I was just wondering if anyone else has run into this problem, which im sure someone has, After a heavy rain with the Jeep sitting and or driving my passenger floor is soaked with water! Front and rear, I have been trying to chase this problem for some time now, I currently have the seats all out and the carpet up trying to find out where it is comming from, I have had it up on the hoist and looked around underneath, cant find anything, is it possible that the bottom winsheild seal is leaking?!?!?! Thats the only place I cant see.

Thanks,
Adam

I have the same problem. Everyone points to the drain under the cowl and I just haven't had time to remove the ft cowl to see if the drain is plugged. There is a FSB about the door seal but I would see water trails in that area. Just an FYI. I worked in a new car dealer for 13 years and water leakes are a bugger. Don't listen to the posts about the AC drain or heater core, AC drains only leak in when the drain is plugged and you are running the AC. Heater core leaks fill the floor with antifreeze which has a very distinct smell. If it's clear water it is most likely the cowl drain.

There is a drain hose somewhere on the right side firewall but I am just too lazy to hunt it down. Mine seems to be better after 5 years so I am assumiong the drain is opening up some.

I had A/C water coming in on the passenger side of my Jeep a couple years ago and my A/C drain was not plugged. I found the fix on the internet, seems to be a common occurance. All I did was stick a piece of hose on the drain nipple like the poster suggested, fixed it for good.

Seems to be the seal where the nipple comes through the firewall, as water drips from the drain it gets blown in around the too-short drain nipple and back into the Jeep. On a 100 mile trip I would get 2 or 3 inches of water on the passenger side. After I slipped a foor or so of hose on the drain nipple, problem solved for good. Drain in below battery and between battery and engine, easy to see if you look between battery and firewall. Probably not GAMEOV3R's problem if it is rain related but good to know.

Mine was the heat air inlet under the cowl! Water runs in the cowl vent then drips into the air box! I made a cover to deflect the water problem solved!
