Possible passenger leak location?

I had the same issue on my 2008 G35 sedan. Take off the cowl, clean all that crap out of there and clean the bottom of the windshield. Run a line of RTV black silicone down the channel and stick it back in place. The RTV silicone will be your new seal.

ok, so had a decent rain shower today and all dry!! so im thinking the bypass solved the issue; however, after doing the water test via the windshield and seeing water go to the back of the cowl, it seems that there is a piece that sits on top edge of cowl against windshield...i don't recall my car having this honestly, but then again it may been removed at some point and never replaced and i just never noticed it...some posts i read replaced it with a j hook rubber strip but they were trying to resolved the noises made by cowl rubbing, but it seems something like that could server the same purpose..anyway, this is piece and part number...anybody has this on their car?

Hello, @G37sPhoton, is there any update to this issue?
I now have a small drip coming in from the cabin filter area.
Seems as soon as I tackle one damn leak another creeps up. SMFH...
Thanks!

No worries about the late reply... we all have young and restless lives to live...
In a pinch, I ended up running a small bead of silicone along the entire inner edge/channel of that cowl piece that slides onto the windshield. Thankfully, that solved that leak issue. The original "seal" had all but completely deteriorated over time.
Thanks for the reply.

^^yeah, i think i pondered a similar solution as well, also, i bought some backer rod at home depot and replaced the seal that was in the inner lining of cowl as it was also just brittle dust, not sure how well this stuff works compared to oem seal and or if its more for friction etc but the rubber on top lip of cowl seems to have been the main fix, at least in my situation...good luck, as the water leak issue can be a pain to pinpoint at times and on passenger side can go unnoticed for some time etc...

G37sPhoton I may not have all OEM equipment so I don't understand what seals we are discussing here. Can you take pics or give part nos. of the 2 cowl seals you have mentioned that fixed your problem? My cabin air filter a tech said was moldy so I'm confident this is part of my probs! Thx!

Hey @Texas Boy , this is a quick pick, but hopefully gives you an idea of what it looks like...its probably the main piece , if missing, that will do the trick...if you pull the cowl out, you will see the other piece, foam cord, tucked inside a groove/channel..i dont think that it will be the culprit but if its falling apart then replace it too..Home depot has something similar but def not OEM etc. As far as the seal strip, its fairly expensive from dealer and the piece i bought was 13-15
bucks and works and looks fairly good, so let me know if you don't find it cheap and i will dig up the seller link(airline supplier) as they shipped fast and most important, it works...hope you get it solved.

ILM-NC G37S for the record the guru I talked to also said techs are using silicone like you did. He said OEM seal underneath cowls was a round hollow rope waxy foam and is virtually unavailable from other places. BUT he said if seal cabin air intake probably that will be enough. We'll see!

G37sPhoton I am searching now for backer rod. You were able to buy a short strip of it at HD? I'm seeing big bundles lol. I'm assuming you used 1/8 or 1/4"?

I don't know why the "guru" told you the seals are unavailable- they are, but just too damn expensive for what they are:
$94 for the Sedan p/n: 66834-JK000
$68 for the Coupe p/n: 66834-JK61A
I chose the silicone route as I needed a quick fix. Being that the cowl is only removed when the battery gets changed- what, every 2-3 years or so- that temporary fix will likely become permanent. No issues and I've had tons of rain in the past few months...
But, I appreciate the update all the same...

ILM-NC G37S That's a different seal. It sits on top of cowl. Seals underneath/inside cowl are not avail.
