Water where it shouldn't be...

Hey guys,

Ok so I'm having some issues.. When it rains for awhile I end up having a wet floor (not a big issue since I have mats from Quadratec that I can just pull out and dump). But my question is where is the water coming from? I replaced door seals, window seals (full steel doors), checked the windshield seals...none of it is adding up. I checked the drain tube mounted to the firewall for the cowl drain...its clean and lets water thru. Is anyone else having this same issue?? :banghead: I think the water is somehow getting on my radio too which means its probably coming in from somewhere in the cowl... I have no clue where to start with that though....and my radio keeps going into protect mode and I think it's related to the water....:confused:

It's a soft top with the full steel doors. Soft top is about 1 year old and I've taken care of it.

I checked the seal under the windshield awhile ago when I was in there looking at the wiper motor and it looked like it was in pretty good shape. I greased it up a little with some lube and then when I put the windshield back up I sealed the seal with silicone and everything...

did you drop your windshield and check that gasket between the windshield and the firewall? my old cj leaked like a seive thru that.....

Personally...I think the water might be coming from the vent system... the vents by the passenger and the driver sides will sometimes drip water when it's raining. How the heck can water get in there??

your vent drain may be clogged. under the hood,on the firewall between the engine and the battery tray, there is a rubber hose coming out of the firewall. squeeze the bottom of the hose. it has a spring steel piece holding it closed. pour hot water into the intake cowl and squeeze the hose again. you may be surprised at what comes out. repeat till water is clear. i used 30 sec moss killer in mine as i live on the ocean in a rain forest. drain monthly.

One place that everyone overlooks is the seam between cowl and windshield base. the seam is suppose to be filled with seam sealer which on most of these old YJ's has dried out and cracked. This seam is just spot welded behind the dash and water will leak in just fine there and drip down on the floor, and over the back of the dash. I'd check there, using a hose and letting water just run on that seam.

vents are prone to this, it comes in above the hood and runs down through the duct system and drips under the dash. You can watch it drip in a bad storm.

Aside from that, make sure your drain plugs are in. If they are out, water from the hi-way will spray up through them and you'll find you and your passenger standing in a puddle from nowhere!

This helps the cowl vent leak... Around $15-$20 bucks. There is a way to unclog them to drain better as well. But, Im also hoping to simply keep it all out. Helps keep the whole vent system dry.

I'm gonna check that seam at the windshield base... Were currently having a storm but surprisingly my floor isn't wet yet. Probably will be tomorrow morning. Im almost positive water is getting to my radio or at least to the wiring of it because it seems like every time it rains my radio goes into protect mode till everything dries up... I can live with water on my floor (it's a jeep :) ) but I cant live without tunes :)

Where did you get that vent cover?
