BMW 525i Blower Final Stage Fan Resistor May Fail

(15 reports)

The blower final stage fan resistor is known to fail. Symptoms are the heater fan speed varies regardless of the setting, the fan will not turn off when the car is switched off, or the fan will not switch on at all.

the fan sometimes on, sometimes off,and now it's dead not on at all. Is it the only possibility that blower final stage resistor need to be replaced? or there's other possibility like fan motor? -
air wouldn't flow so had it insepected and replaced this part. -
Final stage resister failure caused fan to continue to draw power after shutting off car. The battery would drain and the alarm would then trigger when set. -

Buy the part from Rock Auto (<$40) and go on line and replace it. It takes less than 5 minutes. The repair location is under the passsenger side, unclip and remove and replace. Works like a charm, BMW wanted $200+ to replace. -
