    Difficult to analyse without seeing it however does it sound like wind rushing through a partly closed vent ? perhaps your activating solenoid that controls air intake vents may be faulty ! Good luck.

    Does it happen at start up and then go away?
    Is the car idling ok?
    Do the vents change ok?
    Is this happening with or without the air con on?

    Noting to do with start up.
    She idles good for a car that has done 261000 there is a slight flicker of the RPM meter but noting to worry about and a slight shake but noting to complain about.
    interesting that you mention the AC and vents, I hardly use the AC so I did not notice but the vents wont change off the dash window setting till now.
    with the AC on or off tried that last time it come on to see if it could help.
    is there a way to upload audio?

    Sounds like the air con vacuum system manifold or lines are leaking or vac too low to operate actuators. If you are fortunate could be just lack of vac from engine due to blocked line or NR valve in vac line from intake. My VZ defaulted to air on dash only when vac from engine dropped e.g. when car travelling in load uphill. This meant taking dashboard out to access the manifold, so never fixed it. Sold car in meantime.

    Check when accelerating uphill as an example - do the vents change air direction to dash only? That will show if there is a vacuum leak in a/c switching system (hoese or manifold). Used to give me the sh!ts.
