Hi,
When you turn the A/C on, do you hear the A/C compressor engage? It should make a click sound. Do me a favor, take a look through this link and let me know if anything helps:

As far as adding freon to the system, you don't want to overcharge it. That will have adverse effects.
Also, there are two fuses under the hood and a relay I need you to check. All three are in the same fuse box. See pic below.
When you check the fuses, confirm there is power to and from them.

As far as testing the relay, locate another relay having the same part number and switch them to see if that resolves the issue.
You mentioned the compressor was replaced. Was the condenser replaced at the same time?
Let me know.
Joe
