Passenger-side wind noise...

[macky17]

... and no it's not coming out of my passenger.

Above about 80 leptons I get an increasingly loud wind noise, rising to almost a howl as speed increases. I've eliminated the wing mirror, the windscreen wipers and the windscreen sealant strip. Obviously the door/window are the obvious culprits (my gf says it sounds like the door to her ears) but I have adjusted both of them and to my eyes they appear to be in exactly the same position as the driver's side (which is totally silent). Confused. The noise is much louder since I got the car back from service/new radiator but can't see how this would be connected.

Any advice welcome.

Open all air vents. Set the heating/ac to on and see what happens.

I will try. What's the thinking though?

Air doesn't escape well inside Nobles as the pressure builds up at higher speed. The vents, etc. release the air. You may be surprised

Noises don't always 'sound' at the source; they often travel and appear elsewhere.

OK, good tip.

Yeah, noises related to disruptions of airflow are a nightmare to trace. I'd like to see a Noble in a wind tunnel with some smoke.

Worse are squeaks I find

I had a vibrating noise coming from what sounded like the passenger side of the dash... turns out it was up by the courtesy light.

Paul, hope all's well in the glass world.

the top of the windows is a hard area to properly seal and careful adjustment of the window is needed to stop wind noise from there (currently my passenger side isn't adjusted properly and has some noise)... it could simply be the window needs fettling or the rubber replacing.

aha a glazing expert...i'm looking for new side glass for a capri, is this easy/possible to source?

Well that worked. One or two of the windscreen vents were almost closed, probably from cleaning, so I opened them all up: no noise even at 120 leptons. Interestingly, when I then turned on the heater/blower I got noise above 70 again. Opening and closing the passenger vent doesn't seem to affect it. Bloody thing is basically a tuba on wheels.
