Question

Answer
Is what you are telling me is that you tested the blower motor with the battery and it is fully operational ?.

If it IS, What your problem is  there is a fault in the A/C-Heater programmer and or an open wire circuit.

What you need to do is to obtain a full set of electrical schematics and the test procedures in order to find the faulty component.
