Loud thump sound when changing HVAC mode

[Jimsb]

Hi guys I just got my 2016 Camaro a few weeks ago and I recently noticed a one time thump sound when I turn my HVAC mode to recirculation(or when the car starts).

At first I thought it was a problem with the ac regulator motor as the sound was coming from the dash however after checking online I found this bulletin repair notice which suggests the issues is actually caused by a fitting issue.

Whoops, I just realized i meant to post this on the 6th gen forums
