I have a 1994 Jaguarxjs convertible and after 30 mph a whirling sound happens and increases with speed. Sounds like wind rush in. Cannot figure it out. It’s on the left side of the car.

 

Hey Art, is that with the top and windows closed? Under the hood or maybe under the car? If you are able to drive beside a wall (to reflect the sound) you may hear it more clearly and determine if it is from the front or rear (wheel maybe). Also you may be able to record it for us with your cell phone. Make a note of where you place the phone while recording, eg. on top of the dash, left hand end. Also play around a bit to make sure the sound comes with increased road speed and not engine speed.

 

sound comes with top up or down. Will use your suggestion about the wall and recording the sound.
Thanks,
Art
