Hey, Common problem with Jeeps. If you have Air Conditioning, It is your Air Con. I can be more descriptive but google it haha. Hope I helped.

Air conditioner: Water leaks onto passenger side floor from A/C requiring an extension on the condensate drain tube. (1997-03)

This was almost a recall. Mine does it too as does 99% of others. I have floor mats and it will fill with water. I just take my mat out carefully and dump it out. Sometimes underneath is wet but it isn't too bad. I now park it in my garage and it isn't bad at all anymore.

Here is a thread from wrangler forum about it too.

Man, I am getting the hang of being a forumer.

Seriously guys, its not condensation from the A/C. The first response was spot on. If it happens when it rains out, and it's a huge puddle it's the cowl drain.

OP, pour a bucket of water into the cowl and see what happens.

AC99, please read the below message and tell me if this is what's happening to you. This is something I posted a couple of days ago. I'm curious if you're running in to the same thing.

-------------

I know there have been several threads about Jeep's getting water on the passenger floorboards and there has been a lot of good suggestions. However, I've done all of the relevant suggested fixes and still end up with water. This only happens with the Jeep (TJ) in parked, not when it's being driven, so I've eliminated the A/C condensor drain tube as the cause. Here's what I've done thus far.

1.) I removed the cowl cover and cleaned out the cowl drain that's in the middle of the cowl area. Water easily drains thru this now.
2.) I applied RTV around the fresh air intake "scoop" and around the cowl drain.
3.) I sprayed the entire front half of the Jeep while monitoring the leak area. I found it's not coming from the hard top or soft top, it also not coming from the door, windshield or firewall area.
4.) The only way I could get the leak to happen on my own was to pour a bottle of water down the fresh air intake. When I did this the water collected on the floorboard just as it does when it rains.

So, my question is can anyone offer suggestions as to how to prevent this? Is water that gets into the fresh air intake supposed to drain somewhere (other than on to the floor)? If not, what other suggestions do you have to prevent water from getting in to the fresh air intake?

Thanks in advance.

---------------

Based on the above experience, I recently left the cowl cover off and put Saran wrap over the fresh air vent, secured with a rubber band. I left the Jeep outside during a recent rain and found that afterwards the floor was dry. So, I'm 95+% convinced that it's leaking from the fresh air vent. So now I'm trying to determine if I need to build a "shield" over the vent or what. During the rain I noticed that the cowl area was draining properly.

If I come up with anything in the near future I'll be sure to let you know. Please do the same if you come up with anything, I'd certainly appreciate it.

I gave up trying to find the leak, I realized if I park the tj pointing downhill it does not leak. It must be the cowl drain not being able to keep up in a heavy rain.

Take the cowl off...1 screw on each side behind the hood weatherstripping, four just below the windshield, and 1 in the center of the cowl vent screen. Take a hose with a sprayer (I taped one of those flat crevice tools off my vacumn to the srayer to get in a little deeper) and some kind of long flat rod (I used a piece of 1/2" flat aluminum) and spray down the center cowl drain while rodding it with the rod until nothing comes out but clean water. Put it back together and you're good to go untill all the leaves and tree debris plug it again. I've heard of people cutting off the flap on the lower end, but I couldn't get to mine.

I believe I figured out what was causing my leak as posted above. The plastic guard that is part of the cowl piece has separated from the metal. Thai allowed the water to flow down in to the fresh air vent and then on to the floor. Just today I used RTV sealant to affix the plastic guard back to the metal cowl. I'll let it dry overnight and then run a bead of silicone caulk along the length of th elastic piece to ensure a watertight seal. I believe this will work, wish me luck.

The plastic piece I'm referring to can be seen in the below photo.



Also you can see how the plastic piece separated from the metal cowl in the second photo, from a profile view.

I hope this helps you with your situation.

What year/model is your cowl off of? My "99" only has one vent screen (in the middle).
