This noise is indeed coming from the dash and it is caused by a part called the air temperature control blend door actuator motor. The noise is a tiny electric gear drive that moves the door and controls air temperature jumping teeth due to a defective sticking blend door inside the air ducting. To replace these parts requires the dash be removed from the car, a 12-14 hour job.
