If the HVAC mode is changed to include the dash panel vents the noise will be gone. Cause The cause of this concern could be the panel/vent door seals vibrating against the HVAC case when the doors are in the closed position. In some cases, the HVAC temperature setting (hot or cold) could a ect the sealing of the panel/vent doors, changing how noticeable the noise is. Correction: Currently GM Engineering is working on a repair. When a repair becomes available this PI will be updated. Version History Version 1 Modi ed 03/12/2024 - Created on. © 2024 General Motors.
