I recently started experiencing this as well!

Completely intermittent, but noticed most when the HVAC fan/blower is not set to auto, but set to a medium speed range and when braking (never happens otherwise); almost as if something is stuck in the fan/blower and it's making a rapid/fast whining/rattling sound.

Ever resolve this?
