whistling dash vents

[skodafab]

Hi guys please help does your car do this, when one dashboard vent closed usually the pasenger side and the fan above half power we get a very high pitched whistle emiting from the dash very annoying and causes the wife migranes now l know we could just open all the vents but thats not the point we feel that it should not do this the pd didnt so is this just a qwirk of the face lift or a serious fault. Your responses will be greatly appricated to give ammo for the dealers..
