Door Seals during rain
 

I know these are frameless windows etc, but how much moisture is normal? When it rains I get a bit of water past the seals. Seems to happen on the top and the sides (closest to the rear of the car).


I don't get any freezing, squealing or anything the TSBs mention, and the only TSB that applies with my VIN is the door moulding rubber (on the bottom where the window comes out from), which I don't seem to have trouble with. I don't have any scratches from the window felts either.

Where are you seeing the water spots exactly? Just in the places that you show in your photos?

I have a 2013 and I've never had any any of the TSBs done, and sometimes I notice water/condensation getting past the initial seal like what it looks like in your photo. But it never actually gets into the interior of the car, so I just consider it a minor annoyance.

My 2013 FR-S hasn't shown any moisture on the inside of the windows.

I'd suggest you clean up, then treat the rubber molding with something to make it more pliable.

edit: missed what you said. i see them all around the top of the seal basically (where the windows rests when fully extended)

When I looked at the picture it appeared that the water went over the glass and then down the inside and then wicked (capillary action) down the seal.
I believe when the cars were shipped there was a coating on the seal something like wax. It left a residue on the window so people removed it from the seal to keep the window edge cleaner. It was water resistant and stopped the wicking from happening.
You could experiment with some kind of a water resistant coating to determine if this is the cause. [Chapstick would work or a silicone spray or grease to test.]

I've never had several days of rain on my car before, but I've pressure washed my car several times, spraying the water directly sideways at the entire driver & passenger window. I've never had water make it into the interior.
The tail lights, on the other hand.....

my tail lights are totally sealed luckily, but i get the moisture in the windows, in the middle like on the OP's photo
unfortunately this is SOOO common, unless water goes past the effective seal line (= water goes inside the car) dealer won t do much and likely refuse a warranty replace

Im about 2 years out of my bumper to bumper anyway. Just not sure if its the seals or what, because they seem plenty pliable and soft. car's only 5 yrs old. i do see the seal has a bit of wear on the top where the window rubs against it. maybe the windows are tilted a bit too far towards the center line of the car.

Oh, just try it ......:D

I will try it for sure. always love an easy cheap fix.

2017 86 here and I'm getting moisture past the driver's side door seal. When I drive in heavy rain, the next day or later that night, when I roll the window down/up, there will be streaks of moisture on the window.

I'm due for a service, and I think I need to make a warranty claim. This seems like something that could get a lot worse.

Honda Shin Etsu grease works wonders on these rubber seals! I generally reapply it twice per year.

......especially after the dealership gets done messing with it ...... :eyebulge:

The seal won't keep all the water out. No car windows do. It is impossible to make a 100% water tight seal on a window. You see streaks on frameless since there are guides in the center that most framed windows don't have. There is nothing they can do to fix it since it ain't broke.

Sure. I mean, if I take a power washer and shove it in the gap, water will get in there. I've just never seen moisture get past the seal like this in any other car. And it's only on the driver's side. In the same conditions, the passenger side window doesn't have the same streaks.

naw, it shouldn't..my 2013 had nearly the exact same wet spots as the OP whenever my car was in heavy rain or had gone through a car wash and over 60,000 miles it didn't get any worse..in fact I fixed it by keeping the seal clean & lightly lubricated. Perhaps it is dry out there in TX like in AZ. So far my 2016 hasn't had the same issue..

Maybe all just in what you are used to. We get so much torrential rain here that all my cars have done it. Both my windows streak the same but it is just another rainy day in Ontario thing. At least you don't get rain in the day that freezes solid at night. That really messes with things.

I should mention it intermittently squeaks when rolling up/down, as well, both in rain and dry conditions.

That is the wet guides. You can talk to them but I doubt there is anything they can do.
