a/c not working.

the a/c on my 91sc isn't working. the clutch will engage with 12v put directly on it. what could keep the clutch from engaging normally?
 
There has to be a certain amount of pressure within the A/C system. There is a "Pressure switch". When there is enough pressure, and you active the A/C the system will engage the clutch, but if there is not enough or no pressure at all, the system will not engage the compressor. You might have to take it to a shop and see if it has any leaks.
Hope this helps.
