Hi,

I have a C4 mk2 2011 VTI 120. Problem is that the cooling fan does not work at all. I have done the following thinks.
- Checked the fuse for the Fan - ok
- Replaced the fan relay - ok
- Measured all the cables coming to the relay
- To the 4 wire connector come 3.5v, 1.3v, ~12v, ~12v
- Main cables 12v
- Fan works if connected straight to battery
- ODBC no faults
- ODBC gives a cooling temperature
- AC not working due to the fan not working?

Any hints what else needs to be checked or replaced. I have not replaced the ECU or the coolant sensor.
Is there more sensors that the relay and the coolant sensor?
I found the big fuse 60a for the fan but is there any other fuses.?
