e39 530d heater fan

[billy5]

hiya all,,
got a problem with the blower in the car.
all is working with the heater, temps are ok and all lit up.
the fan is not working.
does anyone know where the fuse is for it.
its a 40amp, checked the glove box fuses and the boot[ its a tourer]
and no luck.
any ideas,, ta bill.

I'm afraid its unlikely to be the fuse. It's either the final stage resistor which controls the fan and its functions, which is a common failure point but one which usually manifests itself in ways other than simply no fan, or its the heater blower motor itself.

I had exactly the same problem as you. It was the heater blower motor, and I had BMW replace it at a cost of £330.

hiya fox,
thanks for that,
do you know where the fuse is,
werth a try.
had a prob 12mths ago were the lot went off,
no display at all, two days later back on.
been ok since this.
its a 2001 e39.
we live in the outback in wales and its murder in the
mornings without that boost.
thanks,

Can't remember where the fuse is unfortunately.

The failed final stage resistor, or hedgehog, will cause things like erratic blower motor speed, and the blower coming on with the car off and flattening your battery. Although it can cause the blower to not work, this is rare.

Both myself and a friend have 2001 530i's - and they both follow the same pattern of stuff going wrong. We've both had the same issue and both times it was the heater blower motor.
