Hi John, welcome back. My name is***** you are using a charging station you will need to put power to the compressor clutch in order to charge the system. The refrigerant cans won't get enough pressure into the system to activate the compressor. Use a fused jumper lead to jump power to the clutch wire from a hot fuse or from that terminal block right in front of the fuse box. Once you get about a pound of refrigerant into the system the clutch will engage on it's own.
Let me know if you need anything else.
