Heater/cooler fan shuts off totally at times in my E36 318 i.s.coupe.?

Question

The split zone climate control readout still shows an increase in fan speed when I try to adust but the fan doesn't work. Then for no reason it runs. The ambient temp is about 32C when this happens. The A/C works well when the fan is O.K. and brings it down to about 6C....If it's the fan motor resister, where do I find it? It's a December 1996 reg U.K. model with f.s.h. I've had it for years with no other real probs.

Answer 1

the resister is at fault BMW ones just have mind of there own when they play up! i think its up the drivers side of the blower box on that year.

Answer 2

this happened to my bmw. were you turn the heater up and down its the unit itself that needs changing. about £25 from bmw breakers.

Answer 3

I think you may find that the motor may be on its way out. If it was the resistor it would still work but only on full speed.

Answer 4

I had this with a 98 323i coupe.  No fan in very hot weather, thus no cooling.  An aircon service may solve it.
