Do you get hot air on the heater settings and just no cold air with the A/C, or is the whole thing dead?
On the vent setting, is the air warmer like the heater is turned on; or about outside temp?
Is there a belt on the compressor?
Does the clutch (the very front part of the compressor) click down when you try to turn on the A/C or turn on defrost?
Are your fuses intact?
Do your A/C fittings have threads, like a tire valve (then probably R12); or snap-on fittings (then probably R-134a)?
Is there a sticker on the radiator support saying "Converted to R-134a"?
Plenty of info to be gained from looking around your engine compartment and describing what your symptoms are.

Answers:
- It is a manual, a single dial ranging from "0" to "Max"
- The blower, meaning the fan circulating air through the interior, yes it works.
- Heat works fine.
- The center vents return outside air. If it is cold outside and the heat is on, they return cold air.
- There is a belt on the compressor.
- The clutch does not kick down. The very front of the compressor is unaffected by changes to the A/C or defrost settings.
- All fuses look fine.
- The A/C fittings have threads, there are no stickers or anything denoting R-134, the compressor says R-12 on it, though I realize that is not super informative.
