But remember, the voltage will come Only if the ECU is asking for the fans to spin. If the car is cold and AC is off, most likely the ECU won't send any voltage through the blue wiring. If the coolant temperature reaches 105°C , the ECU MUST ask the fans to spin, otherwise the car will overheat
How much voltage is supposed to be going through the purplewire?
@@zion-n3y1w it oscillate between 7 and 14V. The higher number will trigger the fans for max speed.
