A/C compressor not coming. Change fan control relay. That is mounted under the battery. I check all the fuses okay. A/C system charge up with Freon. Still not working. What could be the problem?

We need to start with checking for power at the compressor clutch. If you have power when the A/C is on then most likely the compressor has failed. However, if you have no power then either a power supply issue or you could have the system overfull. If that is the issue the pressure switch could cut off the compressor. Also, there is a chance that the pressure switch is the issue.

Let's start with checking for power and go from there. Here is a guide that gives more detail on this issue:
