My 2022 refresh Sierra 1500 AT4 has a loud clicking noise in the cabin under the passenger side dash and it is the a jammed air gate, presumably for the fresh air system. I was quoted $1,400 to fix it, but the service rep told me they had seen this issue before, so I thought I would 1.) reach out and see if others have had this issue, and 2.) see if anyone has been able to repair it themselves. I understand that the fix is almost all labor and that the dash has to come apart. I know everything is packed tightly in there, so it could be a big deal to get to this part, but I don't think GM's flagship trucks should have this kind of issue 2-3 years into service. I've asked the dealer to see if the GM would participate in this since it was noted to be something that's come up before. Anyway, I would be grateful to hear any similar experiences/solutions. Here's a quick vid of the obnoxious sound it makes: https://photos.app.goo.gl/MBLXVhvMhryjrzUn7

I have a 2022 1500 AT4 refresh doing the same thing.
