Electronic hum under right side of dash. Accuator

[bstrada]

HI all new here. 2011 Tahoe Hearing and electronic hum and almost like the accuator is searching. It does go away in time. I know the GM accuators ratchets strip out and clatter like crazy but this seem like something electric small motor noise like it searching to find the position? Any thoughts would be appreciated

Does it change when you adjust the HVAC settings?
