I kinda understand how the A/C system works but not 100 percent. Is there any material I can read and try to understand it better. My A/C is acting up again and I know my Compressor is weak so I just bought a brand new Denso unit. I don't understand how the condenser fan works. Is it supposed to be on all the time or just when the A/C is on. Mine isn't on all the time it cuts in and out. When my compressor starts acting stupid then the condenser fan isn't on at all. I'm trying to understand how this works so i can troubleshoot a little better. Because right now I'm very confused on how everything works together.
