    Default Xantia cabin fan

    Does anyone know if the Peugeot 406 cabin fan is a straight drop-in for the Xantia? My fan is starting to malfunction (I suspect ageing electronics in the control unit), and I know where I can get a Peugeot one.

    As far as I can tell from photos the fan itself is the same but I can't tell if the positioning of connectors, mountings & control unit is the same.

    Many thanks

    No, the 406 is different, it blows the other way.
    The electronics aren’t to blame, they either work or the fan goes flat-out.

    Open above the passenger’s floor to see what’s happening in there.
    The connector may be loose or blackened from overheating.
    The ignition switch can be intermittent, and need a modification to add a relay to the fan supply.

    He's right too - we fitted a relay years ago - replacement ignition switch under warranty and later erratic performance was indeed a cooked push on connector.

    Thanks for that. I've ordered the Pug fan anyway as it'll come in useful for spares one day - especially the control unit. My wife has suggested we put up a shelf in the loo for useful car spares. I think I detected a faint note of sarcasm, but I couldn't be sure.

    There's a thread on a UK website about replacing the transistors in the unit, which I tried to follow last year when the predecessor fan went; but to remove the old transistors you need a solder pump and the skill to use it. I fell down on both and destroyed the circuit board. Luckily there was a s/h fan around at the time.

    Think I've solved the problem for now. The fan was quietly cutting out about 20-30 minutes into any trip, but then after a few hours it was OK again. Pulled it out and dismantled it, and there was a thick dust wad behind the control unit, between it and the fan body. I got rid of that and the fan seems to be OK again. My theory is, this led to the circuitry overheating and temporarily ceasing to function.

    AFAIK, the previous owner had the relay fitted between the ignition and the fan.

    I'm curious about the Pug fan blowing the other way. The Citroen fan sucks in along the axis and blows out radially - are you saying the Pug does vice versa?

    Cheers...

    Sarcasm? Surely not.............

    You must have a big loo.

    Good it is behaving now - overheating is a fair bet if the connector on the power lead to the fan itself isn't cooked.

    Why don't you get a 12V convertor and use it as a loo exhaust fan?

    Make sure it blows the right way, otherwise your loo will no longer be your library/reading room.

    blowing the other way
    Meaning turning in the other direction.
    The blades are facing the other way, with the outlet shaped to take the breeze from the other direction.
    They must do it on purpose.

    The fan module that fits on the fan is the usual problem in a Xantia. They've come down in price, but are listed on eBay for not a lot. There's a point at which you just buy a new one. Decent power transistors aren't free either.
