When the air conditioning is activated the auxiliary fan relay turns the fan on to maximize cooling
It controls the auxiliary fan, which comes on to aid in cooling during heavy loads.

The 2006 relay is the auxillary fan replay on a 1996 BMW. The BMW is an all American ritzy car. Most prefer a Porsche as well. These cars are very expensive.
You either have a bad fan relay which is easy to change( in the fuse box) or a bad thermo temperature sensor (screws into the radiator). Change the relay first(do it yourself) If they still run then you'll need BMW mechanics for the sensor.
Yes there is, but it only operates the high speed function.
A typical blower motor relay only operates the high speed function.
Swap the fan relay with another like relay.
Typical causes for this car to overheat would be blown head gasket, coolant leak, thermostat frozen in closed position, failed fan clutch, failed auxillary fan or auxillary fan switch, blockage in radiator or coolant lines or an oil leak.

The reason for any relay is to have lower power to the control circuit. If you tried to run the fan directly from the electronic control module there would be either insufficient power to run the fan or you would damage the ECM by drawing too much power and overheating it.
fan control relay
Yes. Cooling fan, engine fan, and radiator fan relays are all the same thing.
