I'm trying to fault find my aircon issue, here's the story so far;
I get an error code - P0691 Fan 1 Control Circuit Low
I can reset the fault which allows the A/C clutch to click in and run for about 5 seconds before cutting out, at that point the error code re-appears.
The engine fan never starts so the assumption is that either the fan is faulty or the control wire (lilac cable) is broken or there is a bad earth at the PCM unit.
The earth I'm no9t sure about as I would have though there would be other issues if that was at fault?
Either way I need to test the fan operation which I know can be forced into life by unplugging the ECT sensor lead but I can't find it. If it does come on then I know the fan is fine and the likely culprit is the cable or earth.
Problem 1; can some one help me find the ETC cable so I can test that?
Problem 2: If the fan is fine then does anybody have an idea of where the likely break point is in the cable or if the cable can simply be replaced by a new one to the PCM unit?
Cheers for any help
