Leaks on passenger floor...
My '98 TJ leaks on the passenger side floor only when it rains not when I use the A\C. Is the fix the same kind of thing as the A\C fix? Any help anyone could give would be appreciated-- It's really wet up here in Oregon!!

Thanks :confused:

I'm not going to be much help to you, but my 2001 Wrangler did the same thing. It appeared that it was a door seal problem but I could never get it quite right. I also checked under the hood to see if it was leaking elsewhere but to no avail. As I said, I can't help you much with the problem but I can certainly sympathize.

Should be the same fix as the AC leak. Check the drain hose that runs down from the air intake in the cowl. They get plugged up and then allow the water to run into the truck through the HVAC system. This has actually been a design issue since the YJ's... Gotta love quick response to common problems from Jeep! ;)

Thanks for the info jeeperman, but what if my drain is not plugged?

Can you tell where the leak is coming from? Do passengers complain about their feet getting wet when they ride in your Jeep in the rain?

If it isn't the drain, the next thing I would check would be the door seals and the windshield seals to see if you are getting any water in that way. Are you just noticing wet carpet? If that is the case, do you have all the drain plugs in the floor? I guess it is possible that water could splash in from the bottom (although I never had that issue with my YJ which never had the plugs in...). Other than that, you should stop driving with the top down when it rains, and your passenger floor will stay dryer!;) Keep us updated as to what you find!

I have the same problem with my 97,but never bothered to look into it.Can't really complain about the leak since i drive it sometimes with the top down when ti's a JEEP,it can handle it.

sroberts 01-07-2006 07:47 PM

The water comes out of the back of the fan unit on the floor, at least that is the best I can tell. I know for sure it is not the door seal or the plugs in the floor. Its a hard top and the top has never been off!! The winshield seals could be a possibility, tell me more about that if you would Jeeperman. I know it's a Jeep, and I should just live with certain things like this, but it just makes no sense at all!! So now I'm on a mission...for a while anyway!

Thanks for all the information, this is a great forum.

From what you are telling me, it is the drain hose from the intake for your HVAC system. That is exactly what happens... The water is supposed to drain out the bottom of the intake, but when (not if) the drain gets clogged, it doesn't have anywhere to go, so it runs into the Jeep on the passenger side floor exactly where you are describing. If that isn't it, I have got nothing for you, sorry!

my 90 yj does the same thing and its not by rain. if it is ac it can leak ALOT

sroberts 01-09-2006 08:07 PM

Hey thanks for the info it was all helpful.

I have an 06 unlimited that leaks(floods) on the pass side. Been to the dealer 2x already. Have had the Jeep 3 weeks. My 00 had the same problem but was fixed. Here we are 6 years later and it still exists. Do any of them not leak? Have not even gotten my first payment coupon yet. May just return it for another. Saharaharry 06 unlimited

sroberts 01-17-2006 06:17 PM

Wow!! I thought that they must have fixed it by now. Does your '06 only leak when it rains?

How Do You Get To The Hvac Drain Jeeperman? My 01 Does The Same But Only When It Pours. Had The Same Problem With All 3 Of My 79 Cj's Also So I Think The Design Flaw Goes Way Back.

jeeperman 01-18-2006 03:54 PM

Honestly, I am not sure how to get to the drain, I think it can be accessed from under the vehicle. It is just a small tube that runs from the bottom of the air intake in the cowl (the big, open to water, verticle air intake that all CJ's, YJ's and TJ's have through 2006). I also found that my 1990 YJ did it, but the 1991 did not, but I installed a "vent scoop" like this one. I don't know if that had anything to do with it, but it did stop the rain from pouring in if it was sitting outside... Sorry I can't be more help guys, but I am sure someone will jump in and help me out, otherwise I will crawl under the truck this weekend and figure it out and let you know.

sroberts 01-18-2006 10:27 PM

That's exactly what I'm going to do is crawl under my TJ to find out where that drain can be accessed from. This is got to be it.
