that im pretty sure is the vacuum reserve tank which is used to operate the heater controls, do you need it? no i dont think so, i think it is more of a backup system if the main vacuum line fails but dont quote me on this, some one else is sure to have the right answer

lol cheers mate it did let out a hissing noise when i pulled the hose off it but after you said that since its been off every time i start the car the aircon relieves pressure or something so you could be right

You really need to replace the ball - if not you will not be able to change direction of your heater/aircon vents. Unless you seal the vacuum lines you will be upsetting the fuel/air mix in the engine. The car can also be defected as you cannot operate the demister with no control over the switch.
