Hello! I have a electric fan that is not working and have never done! I have checked the 60a fuse under electric fuse box in the engine bay, i have voltage in the thick cables that go to the fan. I have tried and hooked up another used fan and its not working either.

I have autocom diagnostic so i can activate the fan manualy. It works on other v70 but not mine.

What should i check???

Check ground 31/2. It grounds the Fan Control Module and the fan motor.
