(Home) Aircon and diff leak

Aaaaaghhhh!!!! After all the nice things I said about my Townie.
Number 1
Air con light comes on but no cooling effect, I have checked the pump pulley, should the pulley face be rotating with A/C switched on cos' its not. How do I tell if its simply a lack of refrigerant or something more sinister.

Number 2
noticed a few oil spots on the tarmacadam, on checking underneath the area directly above the diff casing it's sprayed with fresh oil. This has definitely just started within the last few miles. There is mild seep from the diff nose, so it doesn't appear to be a faulty seal. Is there a breather on the diff??

As usual any help or advice appreciated

Thanks

George
