Alfa Romeo Giulietta Heater flaps test.

After a very frustrating A/C failure, during which I have changed what was most obvious.... the Air Conditioning Compressor. Obvious in that the Clutch had collapsed, and the Electromagnet was open circuit, and finally, the Climate control Electrovalve was dead shorted (0 Ohms).
A learned friend of mine, plugged in his Scanner, and concluded that there was an open circuit in the Heater Flap motor.
So; having come across Mr. Daniel Van Der Hoorne's video; I decided to try this test, before ripping the dash to bits, in an effort to safe going to a lot of trouble, for no result.
I still don't have the A/C working, but I thought this might help others.
Good luck! I know I'll need it. 🤣
