I have a 1990 325i manual with air conditioning. There is an auxiliary fan in front of the radiator that I have never heard running. I have always assumed it was to come on when the ac was switched on but in testing my ac unit (still with the original R12)
this weekend it did not. What controls this fan and how do I test to see if it is working correctly.
