TomFitz passenger side leak check both the cowl and the heater core
09-05-2013 03:25 PM
sesak my Jeep seems to be leaking passenger side near the floor. I can see where the water is dripping in but it doesn't make sense that it is coming from underneath the passenger door, so it is obviously running down from somewhere. The driver's side is always dry as a bone in the rain where passenger side I have to pull up the carpet and pull out the plugs. Am I correct in thinking the cowl seal may need to be checked/redone? Has anyone had this experience before?

fire66dave Sheesh... Hose is clear, windshield gasket caulked, frame sealed, strip where the soft top hooks in sealed... Radio #2 gone and water still dripping. SMH!!

It is completely clear.
I have also looked up under the dash and cannot find where else the water may be coming from. The windshield seal seems fairly new.
First, am I looking at the right hose? And secondly, what else can I look at?
You may also want to remove the air duct cover on top of the hood to clear the duct of debris and check it for cracks. I popped my cover off today after making sure the hose was clear and noticed a nice, cracked duct that I'm hoping some gasket seal or caulk will fix and prevent complete replacement.

If you need to replace the duct, the part number is 55037200. I have found them on eBay, used, for $40+.

1987Wrangler YJ I live in philly and have the same problem as wakeboard236! your cowl and sides may need some new seam sealing
07-11-2013 08:45 AM
wakeboard236 I have leaks coming from everywhere.... Top of wind shield and behind the dash on drivers side and passengers side. The Philly area got hammered with rain the other week and all that rain ended up shorting out multiple things behind the dash. Fix your leaks as soon as possible!!

dancin1 I had the same water problem with my '91 YJ. Water was coming from every seam and button and under the dash. I cleaned out the offending hose, and it was plugged with mud and debris, but, it continued. I read another entry here on the forum from someone that was having the same problem and they had leaks coming from the seal at the top of the windshield where the bikini top folded into the track there, another had a cowl problem, so I replaced the windshield frame and all seals, hinges and even the bolts, siliconed behind them and now, no leak whatsoever.

howy03 I just restored my jeep complete and like others said but the body seams were the biggest culprits seal them with seam sealer or caulking
07-10-2013 05:29 PM
vetteonr Mine was the same way when I bought it a few months ago. The windshield was cracked and the previous owner threw in a new cowl seal he had already bought. I had a new windshield installed, replaced the cowl seal, and made sure the firewall drain was open and now it's pretty dry. Except for the other day when I got caught in a thunderstorm with no doors or windows. It's all part of the Jeep experience.

That's the right hose. I had water pouring on my feet whenever I took a sharp right turn (strange, it only leaked when I turned right). So, after reading this thread, I located the hose under the hood and- sure enough- mine was completely packed with mud. There must have been a gallon of muddy silt and water that poured out of the hose when I cleared the blockage.

My leak seemed to just 'cascade' from the bottom of my dashboard after a rain. I never could find where it was coming from.

Krush I just purchased a really nice 1994 Wrangler S for my daughters first car. When I picked it up there was water leaking under the dash. I just went out, pulled the hose and there was a lot of water and the end was clogged. Cleaning it was a 2 minute task and now all should be well. Thanks for the help.

had the same problem with mine. Look at the body sealer between the cowl and the tub, mine was cracked and leaking. go to a parts store and get a tube of "Flowable Silicon" run a bead on the out side and allow to dry. should take care of your problem...
06-08-2011 07:42 AM
Snowbucks Same leak. I ran a bead of caulk in the windshiekld gasket. Just pulled it open in front of the window frame. AND ran some caulk along the seams where the side body panel parts are joined = terrible leak - GONE !!!

I agree with everyone on the windshield cowl and the vent drain hose. Had this same issue.

Carpets not the cause of the leak but it will hold the water/ moisture from the leak causing mildew or the floorboards to rust. Just something to check and clean if you're keeping the carpet.

Removed my carpet and herculined my tub for this reason.

crafty I cutoff the very bottom of that hose and my rig stopped marking it's territory on my foot.
11-04-2010 06:10 PM
haroldpo6 If you go with a new windshield gasket look some where else besides Quadratec. There gasket is to thin and will not seal. Had to use sealent + gasket to stop the leak.
11-04-2010 05:21 PM
NAVYCHIEF do not remove the hose. squeeze it at the bottom to drain it. run some hot water through it and squeeze again. repeat as needed.
11-04-2010 05:19 PM
NAVYCHIEF do not pull off the hose........no no no. simply squeeze the botom to drain.

mstuartm Had this problem with my 94 Wrangler -- water POURING into the cabin from under the dashboard. Replaced the windshield cowl rubber, and it didn't help.

Pulled off that host, and sure enough, it was totally blocked. Thanks for the suggestion!
09-30-2006 07:53 PM
jeepin92yj i had the same problem in my jeep. it is water getting into the vent on your hood and your drain hose is clogged. take a look under your hood and you will see a rubber hose on the left side of the engine coming out of the firewall that just hangs down about a foot. take this off and clean it out and it should solve your problem.

Water leaking under dash?

I have water leaking in from under the dash. Pretty sure it shorted out my cd player. Would this be the cowl seal? And how hard is it to replace? Do I need to remove my windshield or just fold it down?
Any help is greatly appreciated. Thank you.
