99 Honda CRV air conditioning problems

I had problems with my Air conditioning, the air compressor wasn't clicking(turning) on, the system was charged with 24 oz freon, put new relays,new high pressure switch, new ECM and nothing fixed the problem. I notice that the blower motor fan did only work in high speed when I changed the blower motor resistor that fixed the speed fan and the AC now is working just perfect . Mitchell on demand and all data AC diagrams don't show any connection between blow motor resistor and the AC electrical system , so if you any problem with your AC system first at all change the blower motor resistor.
