Yes, I did it.
Actually the fan connector is absolutely identical with the power supply conector for the hole ECC. So I disconect the power supply conector and connected to the fan, and the fan goes OK. So it rest ECC module (the hole thing from the central console) and the little black thing (some kind a control module with two connectors)
I suspect the black box, because the ECC looks like functioning. At least those 3 rotators for temperature (L and R) and the positioning comuters works OK.
How is possible this because there are no wire directly between the ECC and the fan? All wires goes througt black box?
And there are no 1 2 3 4 positions, is continous linear from 0 (min) to max position.
The fan has two wires, red and blue.
Red is 12V permanently, blue is came directly from black box (resistor as you said)
yes, problem solved.
It was the resitor blower fan.
Note: for the cars with ECC (like mine) is not valid the trick with 4th positions, because there is no 1-2-3-4 positions. All is linear and continous, managed by sensors and ECC.
So the fan will not go at all, not even at maximum and defrost positions. The fan is controled by that black box, and the black box receive informations from ECC (the whole module from the console, who by the way cost more over 1500CAD).
Now the problem is: why that black box goes out? what makes it not working?
This is the questions.
