You jumpered the AC relay and you got the system to blow cold air... so you have refrigerant and the compressor / cooling system seems to work.
You've described symptoms where I can't come up with a common thread, other than the control unit which you already replaced...
Have you checked the wire connection to the defrost grid on the rear hatch glass?
