Wind Noise Goes Away When Recirc Is Turned On.

[OhioBigHorn]

When I drive my truck into a strong headwind I can almost feel a draft through the cab and get wind noise from the front windows. Activating the recirculation seems to help quite a bit not all of it. Has a solution been figured out for this? Seals look ok.

Thank You

sounds normal and possibly just a equalizing of pressure with it on re circ. Another vehicle I drive with the sunroof tilted has a noticeable change in sound when that setting is changed. Just my guess.

 

[OhioBigHorn]

Yeah probably normal. This is definitely the worst vehicle I've had as far as wind noise.

 

[cerbo]

we re pushing a brick thru the wind, LOL. Got to be noise. How much is normal , not sure?

well I do remember reading somewhere about some years and cowling noises or unsealed firewall areas. sorry can t remember more. maybe you ll find it.

Yeah that sounds like a possibility. I will see what I can dig up

Take a look here Home | NHTSA under your vehicle year and there are a few tab’s that cover this issue. Look under structure category.

Mine makes a very annoying noise at highway speeds if the recirc is on. Sometimes it does it with the recirc off and I have to turn the recirc on and then back off to get it to stop. Using recirc is not an option, unless I crank the radio up loud. VERY ANNOYING!

Agreed. Radio up maybe is the best answer. I like the truck otherwise

Yes, there is a guy on here who found there is an area on the firewall where air gets in. The entire dash assembly has to be removed. HUGE JOB!

Hello everyone, I figured Id make a nice post for anyone chasing this noise from the passenger windshield/A pillar area, I've been a Mopar Tech for the last 7 years and am sharing my findings and will post results as we go, second time with dash out, the air inlet seals did not work as i figured. In the pictures attached you will see the area I am getting air through my firewall and making a whistling noise, and it can be manipulated with the HVAC recirc mode door to allow air to travel into the cabin instead of push through the unsealed area.

Yeah I will pass on that

Mine is very dependent on wind speed/direction. It only does it with a really strong side wind from the passenger side.

Sometimes turning on recirc stops it and sometimes turning off recirc stops it. HVAC off always stops it.

Pretty much what I have as well.
