I have already checked the fuse and it is fine. If I bought some freon would that maybe get my air back on? If not, any ideas on what else could be be the problem?
Fan motor could be effected by a fruse/relay. If you have this working but still no cold air then you need to recharge your system.
I would start with electrical components, beginning with fuses and relays (remove and inspect). I would then look at the low pressure switch tied into the A/C line (jump terminals in cable harness plug while A/C is on to see if compressor kicks in). If you know lots of refrigerant is present and jumping that plug makes the compressor turn, get a new switch. If the coolant has leaked out, don't let the compressor run on empty for more than a few seconds. If the compressor never comes on after all this, try jumping 12V to it directly to see it a bad clutch coil (still won't come on) or bad wiring or control circuit. The next step is to pull a hard vacuum on the system: -29.5 Hg is what you want, and see if the vacuum is stable with the pump off and valve shut. If the vacuum leaks out find out why and get it fixed before buying R134a. If you think it might be a very slow leak you could now take a gamble and get it charged and add leak dye. This can tell you how slow the leak is and where, in the meantime you might have some A/C for a little while. EDIT: The blower motor in the dash might just be broken, which isn't affected by the level of freon in the sealed system. Have this blower problem resolved before digging into the A/C system itself, because it might be just fine.
