If the compressor will not come on at all, it is not because the system needs charging. Check for a blown fuse, disconnected wire at the compressor, or a defective compressor clutch.
Remove the freon from the system. Disconnect the compressor belt, then remove the lines. Unbolt the compressor and remove it. Install the new compressor, connect the lines and belt. Pull a system vacuum, then fill with new freon.
