Cool help-water running out from under dash

Anybody else have rain water collecting under the dash, then pouring out all over your feet when you drive? I do and it's driving me nuts. How can you fix it and where is it entering the dash from?

Check your drain tube in the engine compartment- they like to clog up with crap
I just cut the end off mine so it drains no matter what

Location tests and solutions:
1) Cowl intake. Like Lonster said, the drain tube could be clogged. Clear it or cut it.
2) Body seams around the front of the tub. Seal with some seam sealant.
3) Cowl seal where the windshield joins the body. Replace cowl seal.
4) Hinge areas. Find offending hinge; one at a time, remove bolts, coat with RTV and replace bolts.
5) Windshield Seal - start with the bottom horizontal, vertical sides, and upper horizontal. Reset windshield with new seal.
6) Firewall (engine bay) - check for water running into any holes. Seal.

Checked the drain tube. Not that, there wasn't one. Previous owner must have taken it off.

The cowl seal is pretty dry and crumbly. I think this is the main offender.

I had that problem with mine. Turned out that the bottom of the windshield frame is completely rusted out. I ran a bead of silicone across the inside of the lip of the front if the windshield seal for a temporary fix till I can replace the frame and windshield.

yeah, i get puddles, i mean soaked in the floor pan area
is the tube you are talking about 3/4" in diameter with a closing slit in the bottom end of it?
i unclamped this hose and took it off from the metal fire wall fitting
the tube wasn't clogged but i am thinking maybe the slit isn't opening.

if this is even the hose you are talking about.

That would be the one that they are talking about. Its on the fire wall behind the motor. It drains the cowl area while the other side has the vent opening. That is where the water is coming from more than likely. Specially if its just the drivers side.

Find the grill between your hood and windshield. Open your hood and, from the passenger side, you should be able to see the hose that comes from underneath that grill area. Usually, it is tapered to a slit opening at the very (bottom) end. If you can't find it, I'll try to get a pic for you today.

Here is the tube they are talking about. Its behind the wiring just to the left of the valve cover.

wow, now i would say that was clogged. It was more than likely your problem. Because the same little box on the drivers side is where the vent is. Its supposed to seal off but if its like mine it has some age and is not perfect so if it was puddling than it would leak water.

I had the same problem. The previous owner had taken the hose off and duct taped the drain shut.

Glad that was the problem. To help it even more in big rains you can also add a vent scoop. Did you just take the hose off or unclog it?

Holy heck. You guys are my heros! I am so tired of getting my feet wet when I make left turns and getting my stero and underdash speakers wet. I thought I had screwed a seal up when I switched to a hard top...turn out that was also about the time of a couple fairly muddy outings...I'm trying this tomorrow!!!

My newly purchased 94' YJ has the same issue, when there was a significant rain, there would be a puddle of water on my floor mat and under it too. Then when I would move the Jeep or drive it, it would run out from under the dash onto my my right foot.

I first checked the drain hose for the vent housing and when I squeezed the tip of the hose to create an opening it flushed out a wad of debris and lots of water. Then the next rain, still had a puddle of water again in the drivers floor board. I checked the drain tube again, and there as no water or debris coming out.

So, I then looked up under the dash to see that the end of the vent housing was wide open and it seems there is a missing piece from the end of the housing, such as the drivers side vent opening, maybe. There is simply a square hole on the end of the housing and and another section of the housing is above it and protrudes out towards the driver door about 3-4 inches away from the square opening.
