1991 MR2 Turbo A/C working but not cold?!

So I recently purchased a 1991 MR2 Turbo as mentioned above. 
The car is mechanically sound, but as far as the electrical side of things go
you can tell that the previous owner didn't have a clue what he was doing.
There is a JVC dvd head unit installed in the car that hasn't even been connected 
properly, and just under that fits the A/C head. When turning the A/C fan on, air
flows through the vents, although the air wont get cold, nor hot? Yes the ACON button
is on. Does anyone have a solution to this? It would be seriously appreciated as taking
this sort of stuff to a commercial mechanic cant be costly. CHEERS!

    It could be many things.
    Can you hear the AC compressor running?

    You should be able to switch on/off the AC and hear it running in the engine bay.

    As mentioned, there could be any one of several things wrong with it.
     
    If the A/C is working properly, you will hear the A/C clutch click in when you press the A/C button, and the engine revs will rise slightly. If you're out of gas this will not happen.

    The gas is probably empty. You can get it re-gassed but I think that you have to convert to a different gas.

    The car is dropping revs but I can't hear the clutch kicking in. 
    I don't think it needs re-gassing because the A/C should still get hot without gas?
