Just a little problem that starting to bug me..........
When engine has warmed up I switch the heater on to full heat and full speed, lovely and warm for a bit so turn temprature down a bit, still to hot, turn it down some more still to hot, this goes on till it gets down to about 16 on the slider, it then goes to full cold, it seems to be all or nothing and i am getting tired of turning it up and down.
The car has auto setting but the same thing happens seems to blow the same temprature out till about 16 then cold.
Is this a simple cleaning a part job as i'm not very hot on electrics,everything feels like its moving ok at the knobs,
I haven't had a look yet but I suspect the pollen filter is the original.
Any clues much appreciated
xantia hot cold hot cold

The fan that Anders describes is positioned behind the red alarm LED. When you turn the ignition on without the engine running you should be able to hear it run. If not then you will have to remove the radio (make sure you have the code) which will allow you to push it out. Access is quite tight because for some reason Citroen could not afford to add a couple of extra inches to the connecting wire.
The pollen filter is situated underneath the glove box, just remove the 4 screws securing the felt and the filter is behind a flap removed by either sliding the cover off or removing another 4 screws. It may well be a little dirty with a certain aroma.............

Took pollen filter and it was same colour as carpet (very dark grey/black) and full of small leaves and seeds, vacunmed it a bit till I could get a new one !!!! but nothing would budge the muck, Would this cause the smell of horse muck I can smell sometimes when I turn the fan on ? I just presumed the old owner lived by a farm.
Don't think I can hear the fan sensor thing will check again later, are they fixable?
The car has air-con if that matters!!!

The tiny fan is not repairable. The sensor / fan assembly costs £71.
The usual symptom on Xantias when this fan fails are the opposite to yours. The heat sink in the radio is right under the a/c temp. sensor, so if the fan isn't working, the radio heats up the sensor, which turns the heat off. When the fan is working, it draws air from the car so avoiding the effect of the radio's heat. So it sounds more like the temperature sensor has failed. This would be repairable as it's only a simple RTD.

Had the same problem in my Xantia HDi but we don't have a red alarm LED. I had a can of compressed air with an extension nozzle pipe that I use to clean the innards of computers , inserted this carefully through the grill and blew a little. Perhaps I was lucky but it did the trick; I think perhaps the sensor becomes coated with dust that insulates it from small temperature changes.
