Hi guys i followed a water leak and found it coming from the "sponge" on top of the HVAC shown in the pic i took (pic #1) , its soaking wet and dripping rain water on the floor.

I reached my hand behind the wires (pic #2) to find that "sponge".

I have isolated the cowl last year to prevent rain water reaching that area (as shown in pic #3) and didnt have any leaks until today.

Anyone can help to find and seal the water reaching that area please.

 

read some other threads on this. the screws on the left ,pass, side of cowl screen have holes to drain right above the air intake.i did a lot of work with sealer around the duct through a hole in the firewall,messy but worked. go bach a few weeks to find info. if i can get it ill try to post it. i also did the dam, not enuf, need sealer.

 

carpet still soaked,,after much effort. (Multi-page thread 1 2 3 4)

good info, passenger side door hinge and below are dry, firewall near the kick panel is dry.
Last year i fixed blower motor leak and sealed it with foam when i replaced the heat core and welded new floor passenger side.

My leak comes from top of the hvac where the inner hvac foam meets the air vent at the cowl.

I isolated the windshield and the cowl vent today with duct tape to check if i still have leaks, trying to narrow the problem

 

when you know that the dam you made,as i did, does NOT stop all the water from getting in right above the vent, then you will see why i did what i did. also find other threads on this. there are other leak places.

 

I found the leaks today.
I opened the hood and removed the grommet of the hood hinge. Looked inside and it was wet (pic #1). Poured some water over the cowl and it started dripping inside and gathering around the air intake.

Its the gasket of the Rear edge of hood, its not sealing firmly when i close the hood , and its the screws of the cowl letting water in and also the top edge of the cowl (all areas circled in red pic #2)

The question is is there a drain channel or plug to let water escape instead of gathering around the air intake? where is it located?

And If i seal all those areas with black RTV from the top of the cowl instead of cutting to reach the air vent to save me the headache will it work?

 

look at the pix with the fenders off. see where it drains. those screw holes let the screen drain.in my pix you see a channel above the vent to keep water out of it directly but it drains into the area we tried to dam!.
the only fix i know, is what i did. hard to get fully around the back of the vent where the foam leaks.
i plan to redo mine in warm weather. you see the paint brush i created. i mopped the sealer all around the vent. leak stopped.

i have no idea how it cann be fixed otherwise...

 

you mean drain chanel of the screen and screws goes to the diver side then down the hole in the fender? There is no drain chanel for screen and screws at the passenger side? Just trying to understand how the thing is built.

Another thing to understand is that the cowl under the screen is one block of metal no holes in it except the screws holes, wiper base holes , wiper washer holes. Does water leak from spots other than those since it's a block of metal?

 

read all previous posts you can find. yes the cowl screws must let water drain, at the end by antenna. you can see the duct if you look close at all the pix..water drains on both sides left and right.
water has to drain off the cowl cover or it would lay there forever.
yes its solid metal but drains by the screws. you can see it.

repeat, what i did is the only way i can see to seal around the vent.
sorry, im guessing there are a lot of wet carpets out there!..

the hood leak just lets water in the engine room, not a problem.
you cant stop water from getting the vent area. you must seal around the vent foam.

 

Ok so i opened that area today , inserted my camera took a video of water dripping (couldn't upload the video its too large) so i took some pics.

The thing is i found that i have the old air intake (my jeep is a 1994) with the metal intake (not the plastic one) with the "taller lip" as shown in post #2

Water is entering from the screw Chanel as you said (pic attached)

In post #25 wisnston427 said that cutting and caulking/sealing is not fix for later model XJs like mine.

Just before cutting the cowl i wanted to make sure what i'm doing by asking you first.

Thank you for your help appreciated and Merry Christmas

 

i dont know the tall metal you have?? is it solid at the base? can water get in the top opening?

is there foam around the tall metal?
where is the foam you mentioned?

 

I couldn't tell it it's solid base or is there foam around it I searched and couldn't find answers. Winston427 mentioned that there is no fix for the one I have so I'm confused here

 

if it actually drips on floor away from firewall you might get a Weathertech floorliner to catch the drip, add an absorbant cloth??
just guessing, dont know?

 

Parked it nose down and did a test , no more leaks. Cover it with a nylon blanket for extra safety,we have storms coming. Hope it wont slip and fall on my Mustang
In that position i found 3 drops of water on the rubber floor mats driver side, another leak to search for

 

i dont know how it leaks on driver side, not much. in the engine room i drilled 3 small holes just above the lip on firewall to let it drain on greasy firewall,wont hurt!!, no more leaks on driver side. !!??
