Wind noise

[Manbir Sandhu]

Hello,
I have my 03 Envoy XL for about 3 months, It has 25 000kms on it. Anyways am guessing its still a fairly new truck. Everytime am above 80km i get alot of wind noise. I know other ppl are having the same problem. is there any way to reduce the wind noise? I heard removing the roof rack helps, but i really wanna avoid doing that.

Thanks
Manbir

If your roof rack has the two crossbars, try this: Slide the rear crossbar all the way as back as far as it will go. Slide the front crossbar back until it is at a position equal to the front edge of the rear quarter glass. Roof rack crossbars generate turbulence as the air passes over the roof. The object is to move the turbulence to the rear cargo area...as far away from the occupants as possible. You may also have problems with the door weatherstripping and/or glass channels. Keep in mind, though, your driving a light duty trucks which has the aerodynamics similar to running down the street with a 4' x 8' sheet of plywood in front of you.

Thank you i'll do what u said.

Yup, that moving them to the back thing does help a little bit, but not by a ton. If you're actually going to use the roof rack at some point, you could always remove the crossbars and keep them in the cargo area or in your garage, and just put them on when you may need them. :m2:

I took my cross bars and put them in the garage, like envoy guy said, it helped a ton, but yea there is some road noise that comes from the rear windows, , i just turn the radio up lol

i think a lot of GM cars have problems with wind noise from the windows. You could always try buying window visors. That might help reduce the noise a little.

Another vote for turning up the volume :p

I have test driven a couple of the new Envoy Denalis and they still have some wind noise, though not a bad as my '03. Some of the noise is due to the multi-piece mirrors. :m2:

As said before in another way, not the most "slippery" vehicle when talking aerodynamics, but air/wind noise can be improved. Some areas to look for:
1). Hood deflectors - hood deflectors disturb the air flow over the leading edge of the hood. When disturbed, air rushes around the edges of both windshield pillar posts irratically. This can cause an "air rush" noise and in some instances, whistles/whistling as certain speeds. This is a hard condition to locate as it is actually turbulence created outside the vehicle, by misdirected air flow (i.e. hood deflector) as opposed to an air leak (air leaking into or out of the passenger compartment). The full-size Tahoes & Suburbans suffer from this condition and service bulletin with revised windshield pillar post moldings to address the air disturbance, have been created. (And they work...)
2).Air noise can be created by poor sealing of the glass-to-the window channel. This condition applies to all framed doors where the window closes into the rubber/felt channel. Positive contact and compression of the channel-to-the glass is important when addressing air noise. This is noise which is typically closest to the passenger's ear and the one most noticed. Roll down the window and inspect the contact area where the outer side of the glass slides up & down against the channel. This contact area should be shiny, indicating that the glass is contacting the channel and sealing out/stopping air flow from penetrating the channel. If any area of the channel has a very thin contact line or is not shiny, air is getting behind the channel and creating air noise as it tries to pressurize the area under the rubber/felt channel.
3). Door weatherstrip compression - Are the door weatherstrips actually being compressed against the body properly when the door is closed? You can use the "dollar bill" trick to see if weatherstrip compression is occuring. Test all contact area around the suspect door by holding the dollar bill over the weatherstrip and closing the door, trapping the dollar bill between the door and the weatherstrip. Start to slowly pull the dollar bill out...the bill should have a resistance when you pull it out. The tighter the weatherstrip, the more resistance (drag). If you feel no resistance, you may have located an air leak. Look closely at the weatherstrip in the suspect area. Where contacting, the weatherstrip again will have a shine to the area where it makes contact with the body.
There are others, but these three are the most common ones found. Remember, the more objects you paste and bolt to the outside of the vehicle and create air turbulence, the more chances a wind noise will be created. And again, were working with a mid-size, sometimes noisy, utility vehicle...
(As you can probably tell, wind noise is one of my pet-peeves!)

Hi I have had my '07 Trail blazer for well since '07 i have always noticed the wind noise. I hate it But I love my SUV. I have gone to several site tying to figure out what that noise was an i have found out it is the rear view mirrors. They have a design flaw and that is the annoying noise you hear from the front of the th trail Blazer. when I am on the freeway I feel like I have all the windows down and I really don't. I hope that helps people with the wind noise on the front of the Trail Blazer.

I do have a question I have tis Ticking sound. Coming from it sounds like the control panel but i have no idea what it is. Can anyone help me with that.
:thumbsup:

Search for "stepper motor" on this forum.....that will answer your question about "ticking sound from cluster":)

How do you remove just the crossbars themselves?

I did this mod last week and spent 700 miles on the road over this past weekend. What a difference! Greatly reduced that howling wind, as if it's going to rip my door off. I bought the standard stick on AVS brand it's working out great.

It's raining here right now and I have my windows cracked open a bit to get fresh air moving around. It's really great. :thumbsup:

I have a lot of whistling in the winter time over my side view mirrors, I suppose it's b/c the air is thinner??, and I'm really curious to see if the window visors stop the whistling as well.
