I have a 99 Camry and have found that there is a whistling noise to starts at about 115/120km/h and will continue as the speed goes up, I haven't tried to see if it stops at really high speeeds. The noise seems to be coming from the front of the car (inside) and souds as if one were trying to whistle using a pop bottle, though a little higher in sound range.. Have removed windshield wipers, used tape to cover holes and top of windshield thinking air must be coming in, passing over a void which is creating the noise. Any ideas, rom anyone?

 

u might have an air-leak while speeding ... try using silicon spray on ur door rubbers, window pannels , windshield rubber ... etc.
