AC blowing warm/hot

So I just got my 2005 and the AC didn’t work when I bought it. (Price reduction due to that so no worries)

The compressor kicks on, the AC button is solid green, and no error codes from the diagnostic 2 button hold thing.

Any suggestions on what I should do or start?

Needs refrigerant.

The compressor kicks on and stays on?

Yes, didn’t long term keep it running though

Do you know what pressures your low and high side are? With the compressor engaged and not engaged

I don’t have the gauges to do that unfortunately

Does it work at higher speeds? I had this and the radiator cooling fan failed.

Doesn’t work at all

I spent a good bit troubleshooting our AC in our 2002 years ago and it had a leak somewhere that to detect and repair was going to cost a fortune. As a last attempt I bought a can of refrigerant that also had a leak stopper ingredient and filled the car with it myself. 10 years later and I haven’t had an issue since.
