Hi Guys, just thought Id follow this up for anyone else who may be having a aircon issue.
I visited the garage where I usually take my cars for any work to get the tracking done (it was well out) mentioned the aircon issue and the mechanic said it's probably just lack of gas..I wasn't so hopeful.

Anyway he hooked it up to the aircon machine and the was absolutely nothing in it. He run vacuum and a pressure test and it kept pressure for 5 mins solid.
Refilled with gas and it kicked into life. Compressor working, rad fan working, icey cold aircon. Very happy.

Thanks for all of your replies to my question.
