a/c system blows air but not cold 2006 TSX

I am working on diagnosing the issue. My coolant is low and going to fill that. I am also going to use A/C PRO to recharge the system. Has anyone had good results from that?

I was not able to charge a/c system due to high pressure reading from gauge on charging system. The instructions say that if you system has high pressure, do not add Freon and take it to a service professional. I think it is the compressor clutch as it is not engaging. Any help to test the clutch?
Thanks

If clutch is not engaging (center section of compressor face rotates), then check AC relay for voltage and ground signal (AC enable from PCM) on control line. Alternatively check for 12v at single wire AC compressor connection when AC commanded On. If 12v missing, then AC relay or wiring fault. If 12V present, the compressor clutch coil is open or excessive clutch gap. see attached wiring diagram.

good luck
