I have a 2003 BMW Z4 3.0i, my radiator fan is not working. I switched sensors, I switched fans, I loaded new radiator with coolant, yes I bled it out but my car is still overheating and fan won’t come on. I’ve read where there is this fuse #61, well I think it’s a ghost fuse because I CANT FIND IT ANYWHERE. Does anyone know where the fuse is located that controls the radiator fan so I can see if that is the issue. You would be God to me if you can help as I am ready to tear my hair out!
 
Dunno if this’ll help

Have you changed the thermostat? If no coolant is circulating then it wont get the sensor hot anyway so the fan will never be energised.
Also - check the thin green wire which is in the radiator fan connector - it has a habit of corroding and the copper wire turning to dust. You can see pics here... https://z4-forum.com/forum/viewtopic.php?f=2&t=102083&p=1491546&hilit=fan+wire+green#p1491546
