why is there water comin from under my dash?

Like the title says. there us water dumping/running from under my dash after i wash my jeep. its happened twice now. does it have something to do with the vent on the hood in front of the window? How do i stop this, im tired of wet feet.

You can search through the threads on here, there is someone that asks this every day, and it is in the FAQ's as well. More than likely it is just what you are looking at. There is a drain hose that comes out of that vent on the back of the firewall and runs straight down, this hose gets clogged and the water comes into the vent system and out. Check that first of all. After that check out your windshield and your cowl seal between the windshield and the body. Good Luck.

You need a new cowl seal.

Either that or the drain tube (pass side along firewall) is clogged.

Either that or you own a YJ, they all leak.

Could be a few things. One as you mentioned is the cowl vent. The other could be your windshield to firewall seal. The other could be your cowl to firewall body seal. It's caulked more or less from the factory. After a while it deteriorates. Check other other two options first, as they are the easiest to fix. If it's your body leaking, grap a bucket of roof tar and prepare to take to dash out to fix it right.

The cowl seal is below the windshield, it's where the windshield and tub meet, right at the hinge point.

cleaned my drain tube two weeks ago beacuse it seemed like a gallon would pour on my shoes after a light rain. Since then we had two good sets of rainy days and not a drop of water inside.

check the drain on the firewall on the passenger side. Looks like a black condom. Mine was full of mud and junk and wouldnt let any water drain. and so the water run under the dash pouring onto my feet.

Could you please elaborate on this? where would the body allow leaking? I am having trouble finding a leak of my own, that whole remove the dash thing does not sound promising...

Hmm, how do I put this. Looking at the Jeep from either side, put your hand on the body right behind the hood. Then move it back toward the windshield. The line that is caulked from the factory deteriorates after a while. It will be the crack that is right under your windshield, in front of your doors, and above where the fender mounts to the tub.

I bought one of those in addition to cleaning the drain tube and haven't had a drop of water in mine since. I bought the sccop that crews in with the original holes instead of the adhesive one.

I got ya, thanks a lot!
I have another question... can't you just apply clear silicone on top of this caulk to stop the leak instead of removing a bunch of things to get under the dash? With patience and skill you can make it look decent I think...

You probably could on the drivers side, if that's where your leak is. On the pass. side, there's really no good way to get to it without the dash out. The only reason I done it the way I talked about, was because I already had my whole dash out for some other stuff. Looks aren't really important. Once everything is back together, you can't see any of it. Heck the factory job looks like crap. I guess since we're having this thread, it works like crap too.
