I have a 1998 JGC that is has water on the passenger side floor. I have brought the Jeep in to my mechanic several times, each time they blow out the lines. I still have water on the passenger side. It does not seem to coinside with usage of the A/C as it is winter now and I have not used the A/C in a while. Sometimes I have a damp floor board for a while and then at times it seems to go away. I have read all the comments and don't seem to think it is part of the a/c lines... does this problem sound more like the heater core? could it be something else? I replacing the heater core an expensive fix (greater than say $500).

Well, after reading the other comments, it seems clear that there is a consistent problem with wet floors in the Jeep Grand Cherokee's (and other models), no matter what the year. My '96 is doing exactly the same as the rest of the cars listed. My local mechanic drilled the V plug, blew it out and sealed it, confident that the problem was resolved. Well, that lasted about 48 hours and I'm back to having mobile swimming pools on the passenger-side floors. Since I live in a hot, humid area (Middle Georgia) I need the AC a lot. One note - I've had the Jeep since Dec. 1998. I've had many other issues, but this one did not appear until around 2006. It currently has 152,000 miles on it and is going strong, but this is a real pain. Does anyone from Jeep read these questions and, if so, do they have a clue how to resolve the problem?

A general question to the audience - for those of us with water in the floor caused by a very bad design on the part of Jeep engineering, is a solution simply to drill a hole in the floor to drain away the water? What's the worst thing that could happen if I do this? I don't plan on driving the Jeep through a river or anything like that. I am so tired of the musty smell and wet floor that I'm willing to try it. Any reason not to?

How's it going Jeep enthusiasts? I purchased my '98 JGC Laredo about a year ago (used). When I first got it, my A/C unit was working just fine; after about 6 six months driving my Jeep, the AC just stopped blowing cold air. I haven't taken my JGC anywhere to be looked at because, well, I'm a college student just trying to make it by and don't have that kind of money to get it looked at by a pro. I'm just wondering if these methods mentioned here would work, or if there might be an alternate problem to the situation? A reply to my question would be greatly appreciated. Thanks!

We own a 1995 Grand Cherokee Jeep. We bought it used and the air conditioner doesn't blow out the vents no matter what setting you put it on. It does however blow out the bottom vent by the floor. Does anyone know how to fix this problem?

I have a 1998 GC Laredo with water leaking from under the passenger seat into the rear passenger floor, what do I do?

You would think with all these complaints about the poor design of the air conditioner drain design on these jeeps, that the Jeep company would order a recall and do something about it. I called them, and they don't really care. I love my Jeep, but this continued problem and their attitude about it has made me not want to buy another one in the future.
I did the coat hanger method a year ago, and it fixed it for one summer, and now I have the problem again this year. Evidently, if you park your car, where you will get tree debris falling on it and clogging this drain tube (it runs vertically, from your windshield area to the bottom of the car, by way of the inside passenger floor board, under the carpet), this problem will continue every year. You can find a diagram and pictures of how you get to the drain pipe, on the Internet. I just googled the sentence "water leaking on the passenger side floorboard of 1998 Jeep Grand Cherokee" and it offered all kind of information. But someone was looking for pictures, and it is there if you search.
I have now resorted to leaving the carpet pulled up, and I place a towel under it, when I plan to use the air conditioner. I always remove the towel, and prop the carpet up with a screw driver, so that it stays dry under there. It is a pain, but I am a girl, and I am not great at mechanics to want to fool with this anymore. Yes it looks bad, but I am cool, I live in Florida.

I have a '97 Jeep Grand Cherokee with over 150K miles. The heater core is shot. I brought it to a local dealer who wanted more than $1500.00 to repair! Leaks started in both the front and back passenger side. I live in North Jersery and it's cold! Anyone know someone in North Jersey who knows how to
I'm now looking into a "Mohave Heater". Has anyone installed one of these? Anyone with any results
I love this Jeep which I have had since new, but this is really a poorly designed heating system.

Has anyone felt water dripping on their feet when riding in the front passenger seat? Water drips on the front passenger so I don't think this is coming up from the floor. This is happening in Minnesota in December, so I don't think this is the AC. Does anyone have any ideas?

1990 Cherokee Limited 4x4 here, 170k, same drip problem as above, into front passenger side. I was told it was the heater core as well, but way too expensive to fix. Looking at 98 model JGC's which is how I found this place. Nice site, and good comments.

I have a 1998 JGC and I am less than pleased. Admittedly it has a lot of miles on it but in the last year and half I have rebuilt/replaced the front and rear differentials, the transmission and various other nickel and dime items like the front drivers side inside door trim clips.
It has had the wet passenger floor problem ever since we bought it. I took it to a shop last week and they say its because Chrysler left out a drain outlet. cost to fix it is 8 hours of shop labor plus a small amount for parts. Seems they think the dash has to be completely removed to fix this.
The dealer says its probably just needs to have the drain blown out. Is this an annual fix? we did this once before and it didn't really seem to fix the problem.
Frankly, if I hadn't spent so much fixing it up so it will last the next 100,000 miles I would probably sell it tomorrow.

Hello everyone with wet floor problems. The A/C condensate drain being clogged is not the normally the problem. The problem is where the tube goes through the wall into the uni-body. There is a foam seal between the plastic housing and the inner firewall that deteriorates. This allows the the water to run back down the outside of the tube, through the deteriorated foam seal, and drain back onto the floor. Getting to it is the tough part.
Here is a link showing the place to cut a hole and add a tube which solves the water problem. Good luck to all. http://www.cherokeeforum.com/f5/ac-drain-location-wet-carpet-fix-24246/

My '95 has the same problem. I have been putting off drilling the hole. Thanks for the input, since you said it works, I'll give it a try. Keep ya posted.
