VW Passat Variant 2.0 TDI 16V from 2006 - Engine cooling fans do not work.


The two engine cooling fans do not work, they do not switch on when the switch-on temperature is reached, nor do they switch on the air conditioning. Nor do they work when driven by the diagnosis. The power positive and negative are present on the connector. I would like to know what the electrical signals are and how they are on the other two electrical cables on the fan connector. to make it easier, I enclose a diagram showing the points concerned.
Thank you
Roberto
