I have a few questions regarding the factory Auxiliary (electric) Fan and the Air Conditioning on E30's. I have seached a few times but have not found any definitive answers.
My car is a 1990 325i and the fan clutch and water pump are less than a year old. I have noticed that my auxiliary fan does not run when I turn the AC on in my car. (this is also the time when the temp gauge will start to rise a little). Actually the electric fan will not turn on until the gauge is at the 3/4 mark on the gauge (this only happens at standstill with the AC on). Other than this my temp gauge stays around the 1/4 mark.
My Questions are:
1. Should the Aux Fan run whenever the AC is running?
2. Are there connections that I should check?
3. To me it seems that if my fan doesn't kick on till the 3/4 mark then the lower temp portion of the fan switch isn't functioning properly. Could this be a resistor problem? How do I check?
Thanks in advance for any help/advice.
