    2012 Silverado Z71. electrical humming/buzz below passenger glove box when accelerating and RPM's are at 1500-2000. does it while driving and in neutral when engine is warmed up. I've pulled all radio/amp/speedo cluster fuses and it still makes noise. sounds in area of heater/vent core cover area on passenger side

    I understand how a noise can be annoying especially after you go searching for the source. Please let me know if I can be of assistance.

    Safe travels,

    I suspect a heat shield under the floor, under the hood. Look at the exhaust.

    Seeing as the truck is under warranty (I assume you have less than 36K miles), let the dealer fix the problem.
