Hi all,

In my 2.5 DSE I can't get my blower fans speed to zero and it always shows 1 slot in the speed. I can't reduce it any further. Also, it blows air even when the ign at position II. Can someone help. :?: :pray:

We've had this discussion a couple times now.

I was under the assumption that you could never turn your fans completely off when the ignition was on... but recently a few people have said they could do it if they put the fan speed on the lowest setting and then pressed a/c off.

Give it a whirl.

Small correction kmagnuss, your first need to turn AC off, and then set fan speed to lowest (no dash). I didn't know this until I read it here a couple of weeks ago. I guess that me being in the Caribbean (and you in FL) there's no need to turn the AC off, at all.

yeah... I've never wanted mine off for anything. Hell, even in my old jeep with the top off I still had the fan blowing on high.

Just one question, and I did refrain in previous posts on this topic.....

Why?????
Is having the fans on at a sloowwwww speed such a burden? Why turn them off all together?
Just cannot think of a single time when turning the fans off would be of benefit to me :think:

Hi,
Just to avoid the extra burden on the battery. Mine isa 2.5 DSE, ign @ pos II, the glow plugs need to work. Just imagine EAS compressr, brake mdulator, fuel pump etc etc drawing currents at the same time .

And how much power so the blower fans actually draw? Since the system was designed to do all these things at the same time maybe just leave it as it is. If it is such a worry then maybe consider a larger battery - and when the engine is running then everything is supplied directly from the alternator. I have previously run engines with no battery at all - once they were started - and that included lights and radio.

Hi Rowant,

I was reffering to the position just before starting. as my blower fans start at the [email protected] POS II even without engine running.
Since mine is a DIESEL I need all the power for starting.
As u say, It's true that alternator takes over the supply once started.
But, U don't run an engine (petrol or diesel) without battery connected as it will KILL the alternator within seconds. :naughty:
U may have run engines without battery connected where the old dynamo was in place of the alternator ,Not otherwise.
For that matter, even the 1st RANGE ROVER (classic) was also equipped with an alternator NOT a dynamo.

There's another thing to this story.

The diesels need 107Amps to work. And the manual says a type 664 battery which is rated at 110Ah. But the only battery we can put into our RR's are 95Ah. The next one is too large to be put into the battery case. B'cos of this i even practice the same thing, on every vehicle i own. Before starting i'd switch off all a/c blowers and any lights.

Regards,
Gayan
