As the title and description say, I have the wind noise or whatever you wanna call it around the top part of my windshield at high speeds and i do have a bug shield, which i did assume was the cause. I have heard mentioned that "i had the fix done" or "i took it to my dealer and they fixed it" but what did they do?

 

i need to replace my windshield anyway so is there something in particular I should tell the place to do to prevent this noise?

 

thanks,

Mark

In my case, the noise was coming from the weatherstripping flapping. I ran some silicone around the outside of the window under the weatherstripping and the noise went away. Some have used doublesided tape as well. I would just do it after the new windshield.

I had this problem on my 01 Suburban. I took off the bug shield and installed a hood bra/protector when traveling. I know that the new Jeep Grand Cherokees have a TSB for the same problem with the wind noise without a bug shield and the fix is silicone sealant on the weather stripping.

Okay, thanks. I'll see how the new windshield does and if I still have the noise will try this. I have looked at the rubber around the windshield and it all seems to be tight, attached as it should, etc. so I wasn't sure if it was actually flapping or just the wind was hitting just right and making it sound like it was flapping. It's hard to hang by head out there and watch while driving 65! :rolleyes:

I had the same noise...recently got a new windshield and mentioned it to the guy. He knew what I was talking about and fixed it for me. I am assuming he "glued" that stripping down. For the first time in my 3 years of owning this truck, I don't have that annoying noise at highway speeds!!

Awesome...I was thinking of mentioning it to the guy who installs my new windshield and seeing if he can do something like that for me when he puts it in.

 

Thanks for everyone's input...it confirmed my suspicions of what the problem is. :rolleyes:

I'm just wondering how the GM bug shield will affect the windshield that would cause it some flapping noise. Windshield and bug shield was very apart, I can see the connection. Can anyone explain this? :thumbs:

I don't know why that link shows a mud flap and is talking about bug shields but anyway...the bug shield mounts on the front part of the hood to deflect air upward. The air then hits the top part of the windshield. Mine was making a wind noise along the top. Just had a new windshield put in and the guy said the moulding at the top was sticking up but it looked factory. Nonetheless he said I shouldn't have that problem now and I haven't noticed it yet.

The noise is caused by the bug shield altering the air flow on the truck. To fix apply 3m automotive tape to the inside of the black molding that runs along each side of the windshiled.

When you buy a GM bug shield, it comes with the tape and illustrated instructions how to do that.

 

One alternative is to buy a low profile aftermarket bug shield, such as the one made by VentShade. It does not even reach to the top of the hood, so it would not cause any wind noise.

Beg to differ. Just installed a ventshade two weeks ago and it sounds like an angry squirrel is clawing the top of my truck off at anything over 60mph.

 

Went to the dealer to get it fixed under warranty and they won't cover it. They want 100 dollars to pull the trim and put 14 dollars worth of 3m tape under the trim. I laughed and walked out. I will try the silcone on my own for 3 bucks.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Doing the right thing, replacing both valves is the way to go. The valves with the ball leak far more often than the schrader. Never cared for them. The accumulator really should be replaced if the system has had no pressure in it and it was a keeper, but since you're looking to sell it, bet you can get by. Did you pull the orifice screen and see what was there?   Shame you can't get 134a. Hopefully the previous repairs included dye.   Some of the R4s I messed with developed leaks where the line sets connected or the front seal. Had one where the HPCO was leaking. Front seal would only leak under pressure. See any obvious oily spots?   I've got nitrogen I use to test pressure and to help dry the system prior to evacuation.   Keep up the good work

      Next time you're on a road trip to a state where you can still buy it stock up on 12oz cans, you might look into getting certified so you can buy it where you are as well. When they switched from R12 to R134a the test for certification was easy, they basically just wanted the $25

      Getting greedy...   The AC pump has been replaced at least once per service records, and it's been recharged twice since 2018 or so, in approximately 2 year intervals between those charges.   It was done at the same shop...clearly they were enjoying the revenue of recharging the system periodically versus actually tracking down and fixing the leak. I learned that the owner was 88 years old when she passed in 2023, so maybe they assumed only a temporary fix was needed anyway.   The system is basically empty now, the compressor spins freely, so I'm guessing it "just needs a recharge".   I vacuumed it down, and it has basically held overnight. Doesn't appear to leak under vacuum, check! So it must leak under pressure. I don't have a way to pressurize the system and pressurizing it with shop air wouldn't be great for the air dryer (which is probably toast anyway?)   The dryer (accumulator? I'm not an AC expert) has a Schrader valve, but the high side has an old ball-type valve, which are notorious for leaking. It's clearly had schmutz blown out of it at one point because the line/area next to the valve is coated old black crud, which I assume is AC refrigerant residue/oil, or maybe even dirty dye. I think I'll roll the dice and replace the valves. I have a black light around here somewhere so I'll find it and shine it around the engine bay in the dark to see if there's any dye.   I can't think of another way to track down the leak other than injecting some dye (if it doesn't have any) and having it charged up. We can't buy R134a off the shelf here anymore, so I'll run it up to Jiffy Lube and have them do it. I think I have a coupon. At the very least, the charge should last long enough for a year or two, according to history. I think this truck will be long gone by then. But cold AC is a selling point.

      6.2L L87 Powertrain Engine Noise (Lifter Failure) Question

      By clowe1243 · Posted

      Got the truck back today.  Called them yesterday to get an update, and miraculously my truck is finished?!?! The $13k out the door was complete bullshit!  Ended up being over $14k.  They added some bullshit service bulletin that I cant even find, where they replaced my radiator without telling me or asking me, and charging me for it.  Need to do more research into it, cause they leaked the first delivered radiator was ran over by FedEX.  Sounds like bullshit to me. 2.5 Months for an engine swap, which ended up being remanufactured, not new; ****ing ridiculous.  Brakes are squishy as hell, not sure if its from sitting.  Will give a couple days to see it that figures it self out.  GAVE IT BACK TO ME WITH 1 GALLON OF GAS!  Just filled the tank the day before drop off, more bullshit.  My dash cam SD card was formatted, not really much I can do about that. 3 year, 100k GM warranty at least.  Time to sell it and say **** off to GM.  Bad experience.  Cant wait for the survey email to come through.  Overpriced Raptor R, here I come!

      If I forget the phone in the truck, and forget the truck in the phone, and reconnect.  It works great for the day.  Truck sits overnight, and the next day is a no go.  It will connect Android Auto via usb cable, but not bluetooth.   Ive tried Everything in this thread so far, and nothing works for more than a day.   I think I might have to go to the dealer and have them flash the pcm.   thanks for all the suggestions guys. 👍
