Annoying blowing/whistle

[Art3mus]

Hi all. I have a annoying blowing whistle noise when driving. I think it's coming from the front passenger area but unsure. Any ideas of what to check please?

I would normally suggest a leaf trapped in an air vent, or the vent is partially closed causing a restricted air flow...

But in your other post you state that the blower motor is not running.

In that case, I would check for a leaking / damaged door seal,
or door glass seal,
Or a partially open window,
Or sunroof seal.
