I'm assuming CCU is working because I can hear the compressor click when pressing the buttons
Any ideas?

The engine has a temperature switch that prevents blower operation until the coolant temperature gets to approx. 50°C. The first thing to do is to ground the wire to this sensor to see if you get the blower.
If this does not work, and I suspect that it will not work, get a rebuilt CCU.
