My air con light works and it's full of gas but still no cold air ? If I power the compressor direct it works too .... All fuses are good ... Is the cooling fan unit on the slam panel a possible cause of air con not working ?

You need to establish if the compressor clutch engages when you flick the switch - if not then it maybe that there is insufficient gas pressure in the system or some other fault. The light on the A/C switch is pretty meaningless, just means that there is power to the A/C system but it still lights up even if there are other faults. Suggest you also feel the a/c pipes when the system is running, one should be very cool almost immediately.
Another good reason to visit someone with proper test gear, they will be able to test the residual pressure in the system and then the high/low side pressures when the compressor is operating.
I think that the fan under the slam panel would only be a cause of the a/c not working if you ran it with the car stationary.
