The compressor may not kick on with low refrigerant. Did the a/c cool less and less over time or did it just stop working? If it just stopped working it could be a number of things. Have you tried jumping the relay and the high pressure switch. If you jump them and the compressor kicks on, you need the one that you jumped. Try that first.
Oh, by the way, If you turn your a/c on, your a/c fan should stay on.

On the high pressure switch- I think on your car, it is on the receiver/drier, which is that big bullet looking canister. I think it's right next to your condenser. There is an electrical connection to it. Unplug it, bend a paper clip like a "U" and stick it in the to slots in the connector on the harness. That's how you jump the pressure switch. Do it with the car running. If you hear the compressor kick on when you do this, then it needs a high pressure switch.
On the relay-Look for the a/c relay in the fuse block under the hood. Pull the relay out. If you have a relay that looks identical to the a/c relay in another slot, you can put it in place of the relay you took out for the a/c relay(of course don't pull out a relay to use that will not allow the car to run. Do this with the car running also. If the compressor kicks on then that is what you need.
