Hi I'm having problems with my M3 EVO the Radaitor Fan stays on all of the time??

I had a look at the contacts on the rad switch and they seemed ok,but I found what looks like an inline resistor that was red hot to touch!!! Could this be what is tripping the fan on and if so does anyone know exactly what it is and replacement possibilities ???


Thanks C

I suppose that if the resistor was burnt out then that could be the reason.

They other cause would be your engine overheating and the fan being on constantly to cool it. Does it come on when you first start the car in the morning?

Is your temp stable?

<span style='color:blue'>&quot;So my BM makes me a flash bastard? Then I guess you're just keeping it real from the seat of your nova?&quot;</span>

<span style='color:gray'>&quot;...and the home of the brave..... is bravey 130bhp from a 7 litre engine? 100bhp/litre or don't bother building it!&quot;</span>

<span style='color:red'>&quot;Aaahh the UK; where every road is jammed, under construction, poorly maintained and unfairly policed, at least we don't get over-taxed for it........ HA HA HA!&quot;</span>

Hi Comes on as sson as you put the ignition on before the car has started, so the temp is cold
Do you know what this resistor is called so I can source a replacement?

Cheers C
