High frequency noise coming from dash when in 4WD


Recommended Posts

I think GM did sort of solve the problem within their response. " only heard when the radio and HVAC and other accessories are off". So what GM is saying to us is that if we just turn our radios up and crank the fan, the noise is gone! Thanks GM and your engineers for all the hard work you put into solving this problem.

This isn't a total fix, but have your dealer wrap the transfer case module in two layers of sound deadening insulation. It doesn't completely eliminate the sound, but makes it very tolerable. The only time I can hear it now is if I turn everything off and hit the gas pedal. Even then it is very faint.
