1. Engine off, put a wrench on the center of the AC compressor drive plate, and see if you can rotate the compressor clockwise. There should be a little resistance, but should not be locked up. If compressor is locked up, you're looking at minimum) of new compressor, new condenser, new drier, back-flushing out the AC lines from the drier to the compressor with solvent.
2. If compressor is not locked up, maybe the R134a has leaked out enough where there is insufficient pressure to activate the pressure switch to "close" the circuit to the AC compressor. Read the low side and high side pressures, post those.
3. Whatever you do, do NOT add any sealer or refrigerant containing sealer. And do not blindly add R134a, "thinking" that it's low.
4. I suggest an AC specialty shop or an independent local ASE-certified mechanic since your post indicates that you are not that experienced in AC.
