3-Series (E46, E90)Chat relating to the BMW 3-Series from 1999 to Current. Models include: BMW 316i, BMW 318i, BMW 318Ci, BMW 320i, BMW 323i, BMW 325i, BMW 330i, BMW 328 Ci, BMW 328i, BMW 325i/xi, BMW 330Ci, BMW 320d, BMW 330d, BMW 335d.
I have a 2000 328Ci manual and the radiator fan does not cut on. It doesn't cut on with the A/C on or when the car gets hot (car will evently run hot). How do I test the fan to see if it works or if it's just the temperature sensor or a swtich? And if I have to replace the whole fan how difficult is it to replace myself?
Thanks for any info and help!!
follow the wire that comes out of the fan motor and disconnect at the connector. apply a 12Volt voltage and see if it turns with a "whoooooosh". YES, then fan motor is ok... NO, or turns sluggish; it's time to replace.
There are no relays or switches; fan is controlled by the IHKA module.
Guesstimate time to replace a fan motor for DIY.. 2-3hrs
