Weird wind noise
 

This is (I think) a new one.

I'm hearing wind noise around the driver's door. I've done the wind triangle fix; but this seems new. It's like the window is slightly cracked or something.

Oddly enough; if I roll the window down a smidge the noise disappears. I've checked the outside and nothing seems to be folding over; I can't see any physical change when the window is completely closed vs. rolled down a teensy bit.

Any ideas?

The window bump usually works as you have found out.

This worked for me.

Yes, this is a common problem. I had it on my '07. I didn't try the above link suggestion but it's worth a try, I just got used to the "window bump".

What is the wind triangle and wind bump?

If this is a "sudden onset" problem, then you need to check your "wind triangle" fix. The triangle trim is a subtle problem and requires careful repair and I think many fail to appreciate this. Some people do this repair without attention to detail and it is reflected in the effectiveness and durability. Sometimes substitute materials or adhesive are used and although there are lots of suitable substitutes, not everything is OK.

The "Wind Triangle" fix is to remove the little black plastic triangle in the corner of the front window (behind the rear view mirror) and seal the holes with silicone before replacing it. Google "JMcraney fix". The "Wind Bump" is to tap the electric window switch to move the window down maybe 1/32 " (just to relieve the pressure on the top window seal). Works wonders if the seal is old and leaking slightly.

i think the triangles are probably ok. I used new parts for the repair (with the little fins) and then covered them with the 3M sealant pretty well. I didn't have any real issues before but I did the triangles as a prophalactic fix.

@johnnyg66 thanks for that thread; not sure why I couldn't find it. Seems like exactly the issue I'm seeing. I bought some of the Shin-Etsu grease for the door seals on my LS430 I'll look into it; and the modifying the top tip where the door card sits if necessary.

'll report back if I make any progress.

Thanks!

Well I can report that hitting the bottom window seals (the ones that sit on either side of the glass) with the Shin-Etsu grease seems to have dramatically reduced the problem. I could see them pulling away from the window as it closed; but now I can see it sitting up against the glass. General wind noise seems to be lower as well.

I'm parking the car in a place where it gets a couple hours of sun on the driver's side; so it seems like those seals and plastics are drying out faster. I'm surprised that the seals (especially the door seals) seem to dry out more quickly than my LS430 does; but it may be a result of the history of this particular car.

Interesting. I'm in the same boat. I did the "fin" triangle fix and very, very well sealed under it. I also did the doors with Shin-Etsu grease.

When driving say under 40, it's like a tomb (the above fixes did help) but, when I get on the highway (65-80), I get wind noise. Not bad but, very noticeable (I was a LS400, and a LS430 owner as well so there is a level of quietness I expect). I never thought of hitting the bottom window seals.

Question, did you just go over the top of them, or did you wedge your finger in and get bottom of them ?

I'm very low on Shin-Etsu grease (Had it through my LS400 and LS430) but, should be enough to tackle this.

Dave: The window switch "bump" doesn't help? It pretty much got rid of the wind noise on my '07 (don't have this problem on the '14).

Pulling off the door panels is not something I want to tackle this weekend, I am sure it's easy but, it's time consuming. The OP noticed he covered the window seal with grease, so figured, it would be quick thing to try, I wanted to see if it would help.

Wanted to go through easy stuff before getting into the bigger fixes. but, yea, that does sound like it would help.

Well, I was referring to the window button "bump", not the window seal "bend"

;)

I just hit the side that faces up; opposite the sides that touch the glass. I figured that rubber had dried out and possibly shrunk a little; if that side contracts the trim will curl away from the glass and prevent the seal.

The other side seems to have some fuzzy surface so I didn't put the grease on there as it would have probably streaked the windows.

I haven't done a real eval to see if the noise is gone but the car sounds quieter; before I noticed a reduction in wind noise from the window bump (you can see the glass pushes out against the exterior of the car when the door closes but I haven't been in situations where I've had crosswinds which would have manifested the problem before. The bump now almost makes no difference in noise.

Oddly enough I had a creaking noise in my LS430 that was driving me nuts; and hitting the same seals but the outside part that sits under the horizontal window trim seems to have cured that as well. It's annoying because in all other respects the car is so quiet.

The Shin-Etsu grease seems pretty good. I usually use the Sonus Total Eclipse to lubricate the door seals (they also have a tire product with coconut oil that is thicker) but the grease will probably last longer. I'm gonna do the door seals in both cars and my 560 this weekend. The 560 squeaks like a mouse going over bumps so hopefully this will help.

Taking off the door panels is super easy FYI, it can be done in about 2 minutes. Just be careful when you put them back you get the whole top on the rail just right.
