i have an sc300 and a few weeks ago there is this very annoying whistling noise coming from the dash. it gets really annoying when i reach 60mph but it goes away when i roll down the window. im thinking its a small hole somewhere but i cant find it. any suggestions?

 

Yeah my SC was doing this for awhile too. It just recently stopped making the noise over time though. Is it when you are at only highway speeds it makes a high pitch noise?

 

it mostly happens on highway speeds but sometimes happens when i hit 30 or 40
