Water on floorboards

Hey all, I have a 1998 TJ, and whenever it rains, water accumulates on my passenger floorboard, soaking the carpet. Any ideas of what could be causing this?

It's okay, also it seems like it happens when I have the heater on defrost and leg setting, I don't know if that has anything to do with it.

If it is soaking it that doesn't sound like a leak in the top. Try to trouble shoot where it is coming in. I would dump a bucket of water in the grill/vent on the exterior in front of the windshield. Park in the location you have seen this happen before (same slope). My shot in the dark is that it is coming in there and getting through a crack possibly under that body panel then going into the air assembly which is under the passenger dash.

It has happened while I've been driving, another question, I know that under the cowl is the blower air intake. Is there supposed to be a cover of some sort over that?

Some cowl intakes have a cover depending upon the year, but the seals are usually rotted out Make sure that your cowl drain isn't clogged before you dump in that bucket of water too... If you need to remove it, it is the plastic funnel piece that is bolted to the firewall around the center of the engine compartment.

Alright thanks for the info, I will try that when I get home in about twenty minutes. I'll let you guys know what the culprit was

My 06' leaked on both sides and it was the seals where the door frames met the windshield frame...those seals had a 1/4" gap at the top. I removed the top, pulled the bolts loose that attach the roll bar to the windshield frame and pulled the windshield back as far as it would go and tightened the bolts...the roll bar has slotted holes. One side needed more adjustment...so I cut 1/8" off the bar and re installed it... leak fixed.

I did check the cowl as people say the drain gets plugged..... after removing the cowl, I say BS. That cowl will hold 5 gal of water before it runs over into the heater box. You can look into the cowl vent and see if any water is in there.

My '02 leaks in on the drivers side... I was finally able to see droplets coming in from the front edge of the door and running down. I am not sure if I need new rubber seals but I will definitely check out what Timberland is saying here ... thanks.

When I removed the bolts from the tubes that connect the side bar to the rear hoop, they are a big tamperproof torx...tamperproof meaning they have a pin in the center.....I used vice grips and removed them. Then wrapped a 1" ratchet tie down strap around the side bar and around the rear hoop to pull the two together...then re tightened the tamperproof torx. Pulling together, the gap at the top of my doors to windshield frame was eliminated and now the seal fits tight.... no leaks. No way I could pull the windshield frame back by hand and tighten the bolts at the same time. The strap worked great, and you can close the door to see what you doing...it didnt take much strap pressure.

Just a thought, and it doesn't seem likely since you are having water problems when running the a/c, but are your floor board drain plugs in? I had mine out (forgot to put them back in after cleaning once) and drove through some standing water. Took me only a second to realize why Old Faithful was soaking my feet and legs. Good times, as I needed to clean the floorboards out anyway, but that could be part of the problem. Good luck!

Check your windshield frame, inside and out, for rust. Also check the bottom seal on the frame.

I fixed my leaks where the top meets the windshield and along the driver's door by going to
a hardware store and buying cheap strips of sticky insulation for windows which I put in and locked the top back down. Works like a charm same for doors.

Question on this: I just removed my cowl drain to clean it out. I noticed that, attached to the bottom of the hard plastic jug, there is a rubber flapper of sorts that greatly reduces the size of the hole the water and crap run through. What would be wrong with leaving this off, thereby increasing the flow of escaping water?

I just went through this on a TJ at my work (used car lot). 2002 X pkg 78k hard top and full doors. I googled and read a bunch of threads like this. The cowl drain was clear, I pulled the rubber hose deal of the bottom of the drain. I re sealed the fresh air intake on the passenger side. After a light rain it didn't leak anymore and I thought it was fixed. After a heavy Oregon rain storm it was leaking again. Comparing my jeep to the one for sale I found the leak. There was a weld or nub in the passenger side door jamb. The rain would run down the jamb and was routed by the weld/nub into the dash, the water then ran down the dash into the floor board. Clear silicone fixed the leak on this jeep and it now has a new happy owner.

i have a 2004 x and i have the same problem. my passenger side leaks from where the door meets the top and it drips onto the inside of the door and makes a puddle on the passenger side floor. I used a silicone gel to seal the spot where i thought the leak originated but i still seem to have the problem in bad storms.

The Jeep I fixed at work had the plugs pulled but still had carpet so it would pool up. Blackmetal have you replaced the door seal? There is also a seal on top of the windshield frame.

Most lilely leaking around the fan blower where it mounts to the fire wall. Look under the hood passenger side behind the battery. Stopped it with Silicone Seal and Gorilla tape. That was one of the leeks on my 2000. Around 2002 jeep changed the mounting to under dash.

It rained hard on me the other day, and I had pools of water on both sides, I am going to check the seals on my windshield today! Also, I have seen water pooling up where the bottom of my 1/2 doors roll under. Below the plattic window, the doors fold under the bar, I always have water there anytime it rains.. Not sure whats going on..

I had problems with pooling on the passenger side of my '99 after a heavy rain until the windshield was replaced a couple years ago. Maybe a coincidence, but nothing else has changed. Unfortunately now the leak has moved to behind the passenger seat but I am fairly certain it is because of a bad door seal. I think there was recall for the early TJ's to fix a seal around the opening of the air blower intake opening under the cowl cover.

My Jeep is flooding big time in the rain but only on the driver side floor. The water gets a couple inches deep. No idea what It is. Anyone suggest anything?

MY 2011 did exactly this. The dealership said someone forgot to put in the rubber seals along the door, and the drain plug was out. Once they fixed those not a problem since!

Mine was the windshield seal between the glass and the metal. A little silicone that is super runny, like water fixed the problem and it has never come back.
