If you cant hear the fan motor in the passenger footwell then the fan unit has gone, hence why the bars up/down are not making difference & according to that log it is this, so its either got no power or its ******** & needs changing.
Depends where you are, but I can source a new one & replace.
Is the car overheating? Waterpump?
Yeap its the same issue completely as I've stripped some down to research/investigate, not worth even trying to replace parts just the whole unit I found.
