Low speed Aux fan not working
88 735il
No fan operation at what point on the gauge does the hi spped fan cut on? No fan operation with compresor on. I have checked the fan works bypassed: Replaced the fan sensor and temp-2 sensor, coolent sensor works. I have checked both relays hi and low both have voltage and fuses are good. It seems like the resistor maybe the issue I will check that today. I never let the car heat up over 1/2 way which maybe why the hi speed fan does not come on unless bypassed. Does anyone know what value resistor is? |

Re: Low speed Aux fan not working
I was just going to say, sounds like a resistor failure...but you've already figured that out.
