I have a 2006 Pontiac Grand Prix GXP. When I accelerate to a certain speed (around 80 or 85) I can hear a loud whistling noise inside the car..it is constant until I get off the gas, then it dies out. It sounds like it's coming from the front of the vehicle. I was told that it could be a speed limiter, found out that wasn't it. Then I was told it was my supercharger, there is no supercharger in this model. So, I don't know what it could be. Any ideas?
My car is making a really high pitch, constant whistling noise...what is it?
