Electrical problem
2000 BMW 323 V6 Front Wheel Drive Automatic 100000 miles

my radiator cooling fan will not come on. Turn the a/c on and my coolong fan will not come on. I jumped both fans so i do know both fans are good. What do you think the problem may be.

The final stage is a solid state control unit for governing the auxiliary fan speed and it sounds as if you have a bad one. P/N 17-11-7-505-663 or 17-10-7-544-367 depending on equipment level. Go to " realoem.com "for a new fan on line.
