What cowl pieces fit?

[376shovel]

My passenger rear carpet has been soaked when it has been raining. Realized the problem is most likely the passenger side cowl piece not sealing up. The guy who owned the car before me apparently broke off the one mounting tabs, and put some junk replacement screw in another different hole that isn't doing anything. So it's not being held down properly and I'm sure it is the cause of my leak.

So I'm looking to get a replacement cowl piece. First of all what is the part actually called? Secondly, does one from a grand Marquis or crown Vic fit? Thanks.

do you mean the one at bottom of windshield where the wipers are? black plastic?

[RubberCtyRauder]

is it any of these?

I believe it to be #1 in the pictures. The passenger side outermost corner is broken off and the screw is just sitting in the hole chilling. I can pull the cowl piece up with my finger.

By the way, just to confirm, the piece I am talking about has the big piece of weatherstripping on it that goes across the width of the hood.

I doubt that it's the source of your leak.

Any ideas otherwise? I've looked on YouTube and it seems to be a common issue. The only puzzling thing is the front passenger carpet is dry. It is only wet on the rear passenger carpet spot behind the seat, and under the seat where a bunch of wires for the electric seat are coming out of the carpet.

That is why I said it's probably not the front cowl trim piece.

You need the remove the passenger seat, rear seat back and bottom, move the carpet and insulation out of the way and with the doors closed, have someone run a water hose with a steady stream - not high pressure, all around the doors and rear window glass. You should find where the water is coming in. Check all the body grommets in floor pan.

Check the rear molding that separates the roof rear glass and rear passenger glass. If the car has been wrecked before sometimes whoever put it back together may not have sealed it properly.

Unfortunately I can't be positive. It happened once before as I was driving it more regularly so I'm not sure how long it was before I noticed it the first time. This second time I drove it in the rain maybe once, then went on a 7 day trip without the car. While I was away it rained more, and I came back to a soaked carpet.

[376shovel]

And when u say it's a pain to replace, what part are u talking about? The window seal?

[tobiasg1995]

The molding piece on the roof. I forget what it's called. It's just a pain to get to the fasteners from the inside. Sometimes the interior trim pieces can be a *****. If you take out the interior plastic piece by the back window you should be able to see if water is getting in there. Just like fastblac said have someone run water on the outside while you're inside with a flashlight.

So far what I've check is the outside window trim, which seems to look normal, no cracking or splitting, and no signs of water. I also checked the trunk all over, no wet areas. I did discover an area of wetness at the rear right door in between the door and the weatherstripping. I checked the drivers side and found no water there. I took a video highlighting this which can be found here:

Also. How do you remove the door sill trim piece?

I had the same problem with my '99 Town Car. I never did figure it out before I sold it.

They are a pain sometimes. It's easier if you have a trim removal tool. There are clips that hold it in. I always start at one end and gently pull it up, feel for the clips and put the trim tool next to it. To check the door seal, You may have to do this in a dark garage or at night, have someone inside the car and yourself on the outside and shine a flashlight see if you can see any light around the door seal area when the door is closed. I had that same issue on my truck, and had to replace the door seal. I know water leaks are a pain to find sometimes. If you can figure out if it's getting wet while driving or if it just sits, that would help lead in the right direction. If it's getting wet just sitting, look at the top side. Water doesn't run up hill unless your driving.[emoji6]

Water seeks the lowest level. If enough water gets in to soak the pads it will then flow to the lowest level.

Try following the wet up.

Any tube or wire will act like a straw except the water will also flow on the outside.

Does it have a moonroof?

The only puzzling thing is the front passenger carpet is dry. It is only wet on the rear passenger carpet spot behind the seatI had the EXACT same issue with my 2000 GMQ. Not sure if the '03+ platform is the same as -'02, but there is a small rubber flap in the firewall below the blower motor area. You need to remove the wheel-well liner to see it. That is the drain for the cowl and if it gets blocked, you get the exact effect you are having. Take the cowl apart and remove the windscreen-wiper tray and clean & flush that area out with plenty of water. My DD has been dry since I did this last month.

No sir, no moonroof.

I bought a cowl trim piece from a junkyard today. Mine has a broken mounting tab, and one screw goes in but doesn't grab onto anything. I'm going to try to replace it this weekend and use rtv instead of the factory gasketing, like I saw on YouTube.

How are the wiper arms removed?

[376shovel]

Disregard. Found this thread:

Replaced the cowl piece with my junkyard piece
It's not perfect, but it's essentially held down better in 3 locations now. I also pulled the screen out and removed debris. There wasn't a ton, and the big foam piece didn't feel wet. I replaced the foam gasket with a bunch of black rtv and put it all back together. We'll see next time it rains.

Bad news still leaks. Good news is u can rule out a leak from the rear or door seal. I pulled up the front carpet and it is soaked as well. It's coming from the firewall or cowl somewhere. It got more wet just sitting while it rained.

Per post #6 I said it was unlikely the cowl cover.

OK so now you've replaced part(s) you didn't need to. Now it's time to do proper PD. See post #8.

You are correct, but I wanted to replace it anyway since it was broken.
