On my 2010, the "felt" or "covering" on the firewall, extends down the tranmission tunnel. My next step is to try to remove that and then
go in again with the camera.
update!
on 2010+ jaguars there is sound dampening material cover the hole for the duck bill,
however there is a seam which u can pry open
with your hand and stick your hand in,
i then stuck a tube inside the duck bill withmy finger tips. difficult but doable. access from us passenger side of vehicle,
also move that grey hose clip in the center
out of the way or it will stab your arm
Success! I didn't tackle the job myself, but thanks to the many helpful posts on this forum, I was able to give instructions and photos to aid my shop's technician. They did decide to drop the transmission to give more clearance. He used an exacto knife and was able to cut off the tip. Of course, I asked for it as a souvenir! You can see the picture of the tip attached here. I'm looking forward to a dry passenger footwell from now on. If anyone in North Carolina or South Carolina is considering this approach, I can highly recommend HBI Imports in Mocksville, NC.
From everything I've read on this forum, the original purpose of the smaller opening is to seal off the A/C unit to prevent dust,spiders, etc. from accessing the system in this way. When working correctly, it allows the A/C to drain as the water pressure forces open the duck bill. At other times-- when there is no liquid to drain-- it remains closed. Unfortunately, it can get stuck shut. It did this in my case, which leads to quite a lot of A/C condensation backing up into the passenger footwell. I experienced this several times. In order to avoid further water intrusion as well as damage to system components, the duck bill was cut. Many other cars simply have a drain hose down, without a self-sealing duck-bill. By removing the tip, the A/C condensation drains down through the tube and cannot be blocked by a stuck tip. My XK now has a similar set-up to many other cars, with the drain tube being unobstructed.
For what its worth, my XK started doing this. And I mean it was pouring into the footwell. So much much water that every time I turned a corner or accelerated water would just pour out. Condensation on my windows inside... not good, it was going to lead to mold or worse.
I tried the turn on full fan speed and close vents trick, it worked once... then not again.
My fix was easy if temporary.
Listen, I think most of you can reach the rubber duckbill with with your fingertip.
Start by removing the 4 screws and oil cap that hold the engine cover in place.
Replace the oil cap just because...
Crawl up on the engine onto your knees on the passenger side.
Reach back with your hand on top of the Transfer Case and you will feel a little metal hole going up, maybe 3-4 inches. If you angle your hand a bit you can easily get your middle finger up in that hole, just remember high school and you will figure it out.
The tip of your finger can feel the rubber, as soon as I touched it, water came flowing out over my finger, much like high school...
I simply squeezed and flicked the duck bill and all the water drained out... (ok I wont repeat the high school thing again, but this would have been appropriate here too).
Anyway, now no more leak inside the cabin.
I may put a tad of silicone on my fingertip and rub that on the duckbill to help prevent it from plugging again.
This literally took me 5 minutes after contemplating the big fix and manufacturing a razor tool... for the past 2 months!
This is easy, sure it may happen again, but for 5 minutes, who cares.
In fact, now that I have done it, I could probably start to finish it in less that 3 minutes.
We will see if the silicone trick helps.
According to the parts manual the new style duck bill was introduced at VIN B34499 which is part way through the 2010MY so there will be 5.0L cars running around with the original design.
Based on that, I'm safe. Thanks for the info. I notice water pooling under the car at the back of the engine and assume that's where the new design has sent it.
I was able to get a photo with a scope of what I believe
is the duck bill drain from the AC system.
It is in the location mentioned by by others top center of the transmission.
Was expecting it to be recessed. Based on descriptions.
However, it appears to extend out from face of the tunnel over the transmission..
Can someone confirm that this is the the AV
drain?
thanks
Certainly looks like a duckbill, but mine was recessed and at a different angle. Wonder if they changed design sometime during the 2007 MY or if yours was a replacement by a dealer servicing the old clogged design.
Interesting...I found the hole seen in the photo posted by timbob; the one between the two plastic bolt things. However, while I located the hole with a borescope, there was nothing protruding from it. While I couldn't angle the borescope to see inside the hole, being somewhat long-fingered I could reach nearly an inch inside, yet didn't feel anything in there.
Perhaps it has been removed before I got the car, or maybe this pre-production car never got the duckbill in the first place.

Interesting as if there is nothing there where does the water go. Based on looking at the rubber ducky it looks like it is installed from the inside of the AC evap. box.

Indeed, I'd assume the water just drips from the hole the duck bill would be fitted on, and then down the other hole. Perhaps I'll try to have a look at with the borescope with the AC running, just for the peace of mind.
