DT Body Wind Noise (Tea Kettle noise/noise from passenger A pillar interacting with recirculation HVAC mode) (Solved) (Tech)

[Mitchell075]

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.
You can see with the images below, without light no noticeable leak, with light there is three little dots in the very last picture, this is the common area to find the leak. It was also verified using soapy water and compressed air to simulate driving. Spray the inside with soapy water and blow compressed air into the corners of the air inlet/A pillar sealing areas.


**UPDATE

Just got done putting it back together after using seam sealer for the cracks, test drove and wind noise is gone

What are you using to seal it? Mine makes the same noise from the passenger side and gets quieter when I switch from recirc to fresh air. Weighing if it's worth pulling the dash to fix it or not.

Did anyone ever fix this? My 2022 Ram 1500 Bighorn is pretty loud when I have the recirc button on; but it goes away completely when I have the recirc button off. Any ideas? Think i can fix it by going through the speaker hole instead of pulling the whole dash off? The sound is really annoying.
