2016 siverado making a weird humm
my 2016 silverado is making a strange noise that isn`t steady, it starts for a
few seconds then stops and repeats. it seems to be coming from the bottom
of the truck right under the driver seat near the transmission. its not coming
from the motor and this sound is heard when ac and heater is off. doesn`t
change when turning the wheel. its the same sound youy would hear if a
bearing was going out on something on the drive belt.
