RS. There was a case where the heater's electric fan failed in a car with climate control.
After removing the heater's ECU unit, separating the two halves of the ECU housing, we cleaned the accumulated dust on the electrical part of the board with a brush.
After that, we reinstalled the unit.
The electric fan started working like new.
Reinstallation is performed in reverse order.
