I would have to agree that this is likely the result of the aerodynamics of the vehicle. I can also look into this for you. In order to do some more research, I will need the VIN for the vehicle as well as the current mileage. Please feel free to contact me via private message as well. Thank you in advance and I look for ward to hearing from you.JA said:On my 11 NOX LT1, with only the rear windows down, while driving about 40 MPH, I can hear a "pulsating" noise & feel an air pressure vibration. Worse with windows one-half down, than full down. Anyone else notice this?
this is actually told to you in the owners manual..it has to do with the way the vehicle is built to get the most MPG it creates a pulsating noise when either of the rear windows are down and not the front ones. I know i read it in there somewheres. :beer:JA said:On my 11 NOX LT1, with only the rear windows down, while driving about 40 MPH, I can hear a "pulsating" noise & feel an air pressure vibration.
