Water Leak Under Dash?!?
 
:eek:Every time we get a rain I end up with puddles in my front floor mats. The leak comes from under the dash. I am about ready to remove the cowling and try to diagnose it. Any ideas?

NEVER MIND! JUST FOUND A SIMILAR POST - I'LL APPLY SOME OF THE SOLUTIONS MENTIONED IN IT.

I washed my jeep the other day and found water on the pass. side floor mat also!! And yes the windows were up.

Check for a leak around the AC condensate drain that extends through the fire wall on the passenger side. Mine leaked at this spot after I first got the Jeep. Resealed the area around the drain tube and then clamped a hose to the drain to let the condensate drip out below the fire wall.

don't have an airconditioner...but
 
removed the wiper blade arms and the cowl...
removed the cover to the heater/ventilation blower moter and didn't see any signs of water access there

I removed the cowl

I used an air compressor to blow out the water drain located in the middle of the area covered up by the cowl (beneath the grill on top of the cowl)

Then I used a water hose to spray every thing and I tried to overflow the drain - no overflow and no leak in the cab

We'll see what happens during the next rain - which is already on the way.

Have you made sure your drain plugs are properly installed? Mine weren't when I bought the jeep, and my girlfriend ended up with a very large puddle courtesy of the even larger puddles we were driving through. She took it in great stride and enjoys the jeep - signs of a keeper to me :)

I have since removed the drain plugs completely, and have them in the glove box should I decide I need them. The rain was being forced up the drain hole because the puddles were rather large. I guess that the next time it monsoons here in Florida, I'll put them back in.

I always get puddles under my floor mats in the front I took out the carpet so it doesn't get wet and I have no clue where it's coming from.

I have the same problem - I found that when it is raining, I park with the front of the jeep higher and it doesn't do it - I think it runs off of the front of the drip guard over the side door window and then gets in somehow - I sure can't see where - I know my drain from the cowl is open!

Here is a post about mine and how to fix it, and what can happen if you don't.
7th post down.

No more leak!...I hope
 
After I cleaned out the cowl drain we had a substantial rain. No water in the floor mats. I'll continue to pay attention to it.

i cleaned the drain thing today and found that there way a bunch of dirt and 10 22 shell casings in there so it doesn't leak anymore

I repair and sell Wranglers often. The leak on the left side is common. It typically is the gasket between the winshield frame and the cowl. The factory has more than just the outer gasket too. If you remove the entire w/s frame, you'll see that the factory has butyl tape or some other sealant in there. This is the best way to repair the leak. You really do want to fix it because eventually the water gets into the fuse block and causes additional problems. More than just a wet foot.
