So recently this buzzing noise has began to tick me off alittle and i can't seem to locate a source for this buzzing. It is most apparent around 1900-2400 RPM. The noise is coming from the passenger side maybe inside but definatly the passenger side of the engine bay. Opened the hood and the only things around the passenger side of the engine bay were the cruise control box and the power steering rack. I gave a ride to my friend and he said that to him it sounded like a metal on metal vibration so maybe it is or is not electical...any inputs here would help me maintain my sainity while driving, thanks.
