Cooling Fan Inop 2.0 TS
The Cooling Fan on the car does not switch on at all,either high or low speed. So I have manually powered up the fan to check it works, it's ok.
And having checked the large relay in front of the battery, ok too, having +12v on switched and high output terminals. I assume an earth from the ECU switches the circuit. Which output and how can I easily test this.
Now to the operation of the thermostat sensor, particularly the 3 wires to it. None of the wires have a voltage and I assume that there is a +12v connection, an earth and a signal output possibly to the ECU.
If so anyone give me the designation of the wires. And also if there is a 12V connection where it is fed and fused from?
