Thanks for the feedback all, it is most appreciated!
Unfortunately I tried the Air Con for the first time today and thats not working either - so I've added it to the growing list. Not having much luck so far haha
With apologies if you already know this, but did you have the fan speed above minimum before you pressed the air con button? It's not like a modern tin-top where the air conditioning button brings the fan on, the fan must be started first or the air conditioning won't come on.
Welcome to Aero ownership, I promise it is all worth it once you have it working the way you want.
