Try putting the slider to 0 and press the AC button, as this operates it at low speed. 2016 D4 HSE

Avelingporter, the thread below will at least comfirm that you (and I) are not alone on this....
http://www.defender2.net/forum/topic43156.html ....and thanks RRUK. I hadnīt spotted that! Now if I can find a way to steer the heater fan switch position one to use the AC speed, we will have a useable, and hopefully repeatable solution. Iīll have a look at the wiring diagram. 1998 Tdi 90 SW, 2008 Td4 90 SW, 2012 2.2 90 SW, 2" raised Trailmaster/Terrafirma Heavy Track Raids, 255 MTīs, Recaro CSīs, anorak, wellingtons |

So is the AC on & heater at 0 actually a lower speed than the heater just at 1 then?

Who knows, other than having a fancy tool measuring air flow how would we know?
It is sort of daft though that even with the fan speed set to zero, the air con switch powers it up. No other cars do this! 2016 D4 HSE 1998 110 TUM HS FFR Hard Top XD WOLF 1982 Series 3 SWB Petrol |

Thanks RRUK and Wild Card 90. Again I hadn't thought of using the AC mode. But I usually try not to have the AC engaged to save fuel...well just a bit.
If you could have a look at the wiring Wild Card, would appreciate an idea from someone who might have more idea than me. Cheers. D |

Bin bag liner, some duct tape and a watch should sort it  |

On the way home today; I compared both settings - AC and position 1 heater fan.
I reckon they are one and the same.  1998 Tdi 90 SW,

I fell off mine I was so stunned by WC90's dedication to improving Defender ownership for the remainder of us....
I can picture the scene: A tidily spec'd 90 sitting in a German traffic jam (very clean, ordered and the world's only traffic jams that get you there on time, no doubt), and WC90 working through the configurations: AC on. Listen. AC off. Heating to speed 1. Listen. Heating Off. And Repeat. Maybe again, just for good measure. Come to conclusion they're the same. Consider results and post on forum. A level of analysis, I think we would all agree, that would be worthy of the German giant Siemens.... Monsieur Le Grenadier

I dare say it would be possible to add some additional resistance into the circuit or to change the resistor pack but since we are talking about Defenders and not Rolls Royce why not just shove some cotton wool in the appropriate lugholes. I mean seriously, it's a truck. Steve.

If you fit a snow cowl it will significantly reduce the airflow with the fan on setting 1 (and 2 and 3)! Desn't help the noise though.
