Anyone have leaks when raining behind dash

When it rains I get drips from behind the dash,
on both sides right on each persons shoes
On drivers side it drips all down lots of wires so
I do not want to use a hose to see where it is coming from
I was going to silicone under the windshield to start

From the amount of water I figure it has to be pooling somewhere.
as it will not be raining any time soon but I have lots to do
Exhaust,fix door handles inside and fit ,fix floor

Any suggestions would be greatly appreciated

Thank in advance

My Jeep does the same thing, if parked outside in the rain or when i "shudder" wash it, I get water dumping on my feet. I think it is coming from the vent on the dash. It does not bother me that much, so I have not tried to fix it yet, but I would think that if you close the vent switch on the dash during rain or washing that may keep the water inside till you can find out where it is pooling up. I know this is not much help, but maybe it will assist.

Lift your hood and look for a hose coming out the firewall under the cowl vent. Take the hose off and I bet you will find it is full of junk (leaves, pine needles, dirt, etc.). Clean it out, reattach, and hope that takes care of your issues. Mine did dumped water on me for a couple of years before I learned about the cure right here on wf.

I agree about the vent. You can replace the weatherstriping between the windshield and the body also. Its called cowl rubber and costs $24.95 from It fixed my leak and took about an hour to do. You'll need Torx wrenches. Sorry.

The above mentioned cowl vent is the culpret for most YJ leaks it seems!

If you don't want to remove it, you can crawl underneath and use a long flat screwdriver to open the end and dump the contents. There is a flat piece of spring steel in the end of the tube that gets rusty and stiff and keeps it from letting water and debris through. It's supposed to be closed on the end so you don't suck engine compartment fumes into the passenger compartment. Just be prepared to have some water run down your arm when you stick the screwdriver in the end to clean it out... it's a quick fix, but can be messy!

The cowl gasket was the problem on my YJ, and find it best to do a replacement about every 5 years. BINGO, no leak.

water leaks

the air intake in front of the windshield has a drain hose. it will get plugged. i poured HOT water into the intake and opened the drain hose,by squeezing it. A lot of nasty stuff came out. The hose hangs down in front of the firewall on the passengers side. You gotta squeeze it as it is manufactured so as to keep critters from crawling in. The other leakage problem can be the windshield gasket. My 1994 Renegade windshield needed a little help with some non hardening butyl rubber caulk. Worked fine. I don't ever put my windshield down as it has a purpose......keeping bugs outta my teeth and eye balls.
