I've noticed recently that when turning the climatronic unit off completely on my vRS, that depending on what temp it was set before turning off, there is still a small amount of air being blown out at that same temperature ie. its not completely turning off, unless I physically close the vents to stop the air blowing in. Is this normal for the climatronic system? It gets annoying when the cabin is too warm/cold or need to turn off the system yet still air coming in, happens whether its set to Econ or Auto, also, is there a way of turning off instead of continuously pressing fan button until it goes to 'OFF'?...

In the off position, the fan is set to zero, however when moving forwards then just like any other car with the fan off you will get the Ram effect of air passing over the car front.
