Ventilation blower fan has packed up
Hi guys,
My ventilation fan has stopped working... just wondered if it's more likely to be the switch or the fan itself before I pull the dashboard out? Does the fan have its own fuse, or does the circuit it's on cover multiple items? Everything else on the control panel works as it should, just turning the fan speed knob has no effect at all.
Thanks guys
Dave

Now I'm not just confused, but almightily p!ssed off.
I have a sequential fault. HOW THE F*CK IS THIS POSSIBLE????
Turn ignition on, fan works. Turn ignition off, then on again, and it doesn't. Turn off then on again, and it works. Repeat as necessary.
Is there a relay controlled by the ignition circuit that sends power just to the fan motor? Because if there isn't, I'm REALLY stumped. Every other control on the heater panel works, all the buttons light up as they should, absolutely everything else in the whole car is working as it should, I just have this one annoying fault and because it's obviously not a mechanical problem or a permanent break in the power supply, I'm totally stumped.

Davva, you have every right to be annoyed at your Peugeot Electrics, nothing seems to be simple does it?
It seems Peugeot and Citroen give us these brilliant innovations in car electronic features but they don't have the simple reliability and quality needed in a moving vehicle.
Seems the faults you get can be caused by something completely remote and you would have no idea why, I mean why should a crappy handbrake warning switch say 'Brake Fluid Level Low' and so on.
For what it's worth, I've had this on another car and it was the resistor pack attached to the Fan Body itself, if you have a fan switch that goes 1,2,3 & 4 etc then the resistor pack sorts out the fan speed, they normally blow and you lose one or two of the speeds though, not the whole lot, I would start with that and the switch itself.

I see my 406 has that famous french adaptive fault management system installed, must have missed that particular box when ordering it from Peugeot.
What I WAS doing is... turning the key to the pre-start position, if the fan isn't working I turn it back again and then try again, and without fail the fan would be working so start the engine and away I go with fresh air.
BUT... my 406 has figured out that I'm doing this, and to really raise my blood pressure to the point where the veins in my temples are standing out like lumpy purple hosepipes, it now lets the fan run in the pre-start position... lulling me into a false sense of security... and then cuts the fan off when I start the engine.
Which just about drives me abso-f*cking-lutely BATSH!T.
I've not seen the technical way of resetting the ECU, however I am fully prepared to thrash my car to within an inch of its garlic-ridden snail-eating beret-wearing stripy-jumper-on-a-creaky-bicycleish life with a selection of garden tools, up to and including a combine harvester to see if that will help in any way.
After I've done this, I'm declaring war on France and sending in raiding parties to free baguettes from captivity and stop their unpasteurised soft squishy cheeses from killing pensioners. I'm also forming the SLF (Snail Liberation Front) and will make a concerted effort to disrupt the supply chain to their horse farms as no-one in their right mind really wants a six foot horse drumstick on their table for dinner. Plans to introduce a specially mutated weevil that only eats garlic (and doesn't mind not getting snogged at the end of a friday night out) have been laid and I'm anxiously awaiting the first batch that are thankfully being cultivated downwind from me. Hopefully following all of the above, the average French worker will be too tired from starvation to make any more Peugeots and we can all go back to normality and buy Fords.

I take it your not too happy with the old Puggy at the moment
It is OK davva to be cross with your Peugeot, but in a strange sort of way they are kind of amusing at the same time........as if you are already prepared for such electrical drama's that you simply can't help but ridicule the car.
'Quirky' is a nice little term for french cars........Full of Character
People have documented for years that Peugeot's are great cars, mechanicaly very strong, comfortable, long lasting etc etc but watch those electrics!!!!!!..........seems that will allways bug Peugeot eh?

If you do pull the dash could you take a pic where that thing is????
I just wanna cut the cable SO IT STOPS CLICKING!%"&//§"§$
Can't I get to it without taking half the dash apart? I don't see it behind the glove.
The electrics in the 406 are horrible. My left window and I play this game.. It opens fine, randomly it closes itself, I push the button again to go up and it goes down again. Then I keep trying to close it but it will always randomly open. But if the motor isn't running my window sleeps and waits for me to start the car again. The electrics watch you and wait for the worst time to annoy you... Like at a toll in the rain..
Oh and threatening to junk or scrap it, or kicking it doesn't seem to help either

My W reg 406 2.0 HDi has just started doing this too. Sometimes the blower runs untill you start the engine, then it doesn't. I have noticed that if you bash the stearing wheel cowling on the underneath, it starts to work again.
I think mine must have a loose connection or summut there, haven't had a chance to have a look at it yet though.

Sounds like your window motor might have had it. When they hit a certain amount of resistance when closing (and this is the same for any semi-modern car) they'll back off in case the resistance was caused by a child's neck. Personally I'd prefer my windows to operate under a natural selection philosophy but hey... Anyhow, if your motor ain't generating enough torque to close the window it'll trigger whatever mechanism senses the resistance... Following on from this, your electrics generate less current when the engine's not running which might be why it doesn't work when the engine's off.MaDc0w wrote:The electrics in the 406 are horrible.

Or you might just need some WD40 on a pulley or something...
I thought that too....BUT... the right side window has NO child safety... tested with my arm (ouch). .. no way arround a scrappies visit soon.mjb wrote:Sounds like your window motor might have had it.
