Bmw models that do have an engine driven fan will also have an electric fan mounted in front of the radiator known as the auxiliary cooling fan.
Bmw e39 aux fan resistors.
What happens is the fan will turn on for about 3 seconds and shut off and wont turn back on i have had the car start to over heat and the fan was still not turning on is there another relaly or sensor leading to.
I wanted to be able to have the fan run on a high and low speed so i planned to use the resistor set that came with the electric fan.
Hi i have a 97 bmw 528i and the auxillary fan doesnt come on and stay one when the a c is turned on.
New wiring will be required.
Bmw also applied this to many of the 6 cylinder models through the 2000s and of course all mini models.
Riverjamie lol welcome to the joy of owning a bmw and e39.
This is what you are in for me thinks if your aux fan resistors has gone to get a them front end dis assembly is required.
This fits your.

The fan in the e39 is on a 50a circuit which means that the stock wiring for the e28 aux fan will be insufficient as it is on a 25a circuit.
Sorry had to put this last dis assembly pic of the front end in as the guys just love my blue bmw work shoes first question that lower hose will not get anywhere near as hot as the upper for awhile.
I replaced the resistors on the fan and the temp control sensor on the radiator.
Make sure this fits by entering your model number.
