Ok, so I started engine and on tickover pressed the ECON button. Nothing. I heard nothing different at all. Did it a few times just incase I was missing something so decided that it must be that the compressor is not kicking in. I got out my trusty Haynes manual and looked up the compressor and the first thing I read was 'as no clutch is fitted to the air conditioning compressor (the compressor operates continuously) do not operate the engine if it is known to be short of refrigerant, as this will damage the compressor.' Since I have no idea how long the refrigerant has been empty, I am assuming that the compressor is shagged I will have to get it hooked up to the computer so I assume this will confirm the compresssor is either knackered or I'm talking out of my arse!
