Thanks so much for this. Followed the links and managed to extract the FSR, and through other links took out the black rubbery gunge on top and resoldered the faulty joints.

e46 - Anyone ever had trouble with the Auxiliary Fan not working?
2003 325i e46 BWM here. The auxiliary/electric fan in front of the radiator has stopped working, causing the car to over heat when the car is at a standstill or red-light.
The fan doesn't spin on startup (part of a startup self-system check) which leads me to believe it is either a power relay issue, or a burnt out fan motor.
Im good at fixing cars, but now so much electrical issues. Does anyone know a good way to test either of these two issues?
Or has anyone had any other similar issues? Trying to research all options before I drop $250-$400 on a new fan.
Thank in advance r/BMW
