Fan - all or nothing

Hi,

My fan in the defender is either on or off with no modulation. Is this normal or should it be adjustable? I have lived with it for three years now.

Thanks

James

Well you have seen up in my other post, but in standard form, the lever on the left has a 2 speed fan switch incorporated. Speed one is like a gnat farting though the vents, speed 2 is like Sir Alex Ferguson in a bad mood! As you move the lever up to the top it closes the fresh air flap completely.

With the Landrezieger mod, the air flap cable is left disconnected in the open position, and the complex switch lever assembly is replaced by a simple variable resistor, which talks to a PWM controller that sits under the bonnet, and controls the fan. 2021 Defender 110 X-Dynamic HSE D300 MHEV

Yep I understand the benefit of the mod I am just wondering if I should have had more than the one setting in the first place

There are 4 settings in total.

1) fan off fresh air flap closed
2) fan off fresh air flap open
3) fan low speed
4) fan high speed

Mine has closed and off right at the top. Then move it down and the flap opens before the first speed. Then down to first speed and full speed etc. That is how it should work if the cable is correctly adjusted

Just had a look on eBay

What is your opinion on trying something like this? Seeing as we have a 'rather older' 90, the control knob would not look out of place sticking out of our dash!

It's worth a go, but I wanted to keep mine looking as standard as possible. You would have to make your own wiring up with this I presume? 2021 Defender 110 X-Dynamic HSE D300 MHEV

My 90 was

Off
Low
High

My 110 XS seems to be

Off
Very low - If I leave it inbetween low and off, probably a fault but its quite nice
Low
High

Ah ha I have figured out that I am missing the high mode so I guess it is time to adjust the cable !

The cable only controls the flow of fresh air into the heater system. If you have only one fan speed it will be either the dash switch or the wiring at fault
