Aircon gas leak?

[piker]

Hi i'm new here I got a VR 93 Exec. Last week i upgraded my head unit and had to pull the climate control out to get the center console out and it has the orange rubber thing on the back of the controls it all works properly its just when i change from say head to feet or defrost i get a sound that sounds like gas is leaking is this because something isn't on properly or what?

It is normal for a short hiss to be heard when changing vent positions. The hiss is from air not gas.
