Welcome to the Werkz. Always good to have another 7er on board.

Do you mean the fans aren't blowing air at all, or not blowing cold air(AC)?
Can you hear the AC compressor engage when you turn the cooling on? Does the idle change at all when the compressor engages? If you answer no to either or both of these, you may need to get the system regassed or serviced. I am pretty sure that there is a pressure sensor which will disable the system if there is insufficent pressure.

Let us know what you observe.

Yes it is a twat to change but the results are worth it !!
It is under the footwell so some trims need to be removed and get ready to lay on your back for better access !!
