Question about 2001 BMW 325
What is the fan control?
Posted on Aug 20, 2008
I have a 02 325. The controls were working but not the fan. I replaced the fan control. The part was $80 online and it took me 20 minutes.

Sounds like the problem is more with the blower motor assembly itself. The blower motor have micro-proccers built itnto them which comunicate with the control heads and do the actual regulating of the fan motor. Dealers have computers with diagnostic software which allows them to monitor what is happening in the eletronic controls of the vehicle. Electronic diagnostics without the diagnostic software makes it very diffecult to pinpoint the actual item causing the problem.

Check the relais module located inside under the rh side of the heather box you can see the connector most of them need to be replaced as they burn out you may need to replace the blower motor as well,high amp draw caused by faulty bearings will overload the blower motor controller

According to the schematics on your vehicle, it has a "Blower motor control processor" either built in to your controls, or in line between your controls and blower motor. Yo may get real lucky and find some dirty connections in that area, and get away with cleaning & re-connecting, but I wouldn't get my hopes up too high. You may end up replacing the processor, as it regulates fan/blower speed.

THE BLOWER AND RESISTOR ARE UNDER THE HOOD ON THE PASSENGER SIDE. CHECK FOR POWER AND GROUND AT THE RESISTOR CONNECTOR AND MAKE SURE THE FUSE IS NOT BLOWN.
