If you have Dual Zone Heating / Ventillation / Air Conditioning you might find that either side continues pumping out hot air even after turning everything off - putting the A/C on and switching it to 'lo'
Yep no change - it still pumps out hot air no matter how things were set.
It is a known issue and Citroen issued a 'Bulletin' in June 2006 on it. It can affect either side of the system but from what I could see on the bulletin (had to read it upside down as dealers are loathe to show you them) is limited to a number of cars up to a specific build number
Basically it requires the control module at the rear of the dashboard replaced as one of the 'duct diverter' motors (best explanation I can give) has failed.
It may only require a 'gear wheel' change and not a whole module but if you have any issues with the heating / ventilation system not working as it should then get it checked out by a dealer as it is possibly related if the car is in warranty
If out of warranty - fix for £10.00

There is a common fault that Citroen
This can be resolved very quickly and easily by purchasing part number 6450.xz from a Citroen or Peugeot dealer (they can both order it, my Citroen dealer had it in stock!). you will need the part number as my dealer hadn't heard of the fault (but had the part on the shelf?).
It costs less than £10, and can be fitted in less than 25 minutes for the drivers side. passenger side might take longer due to the glove box. the kit contains enough parts to fix both sides, so if it happens to the other side you don't need to buy another kit.
This was an unbelievably easy fix well within the capability of the weakest diy mechanic. My Mum could have done it.
The Citroen repair bulletin is available for download from this site.
Thats where I found out about the problem. the fault lies with the whole air-con unit not the motor so taking to a air-con specialist would cost hundreds for a problem that Citroen have fixed with a simple modification kit.
