Hi folks,

I know this is sort of OT, but this group is somewhat livelier than the
Citroen one, and since the cars are pretty similar (bar the suspension), I
thought I'd ask....

The fans on my Mum's HDi engined Xantia are switching on continuously, even
with the air-con switched off, and the engine cold.  The water temp gauge
does work, so the sensor that uses is fine.  The aircon needs regassing,
and is left switched off.
Any suggestions for what might be the cause of this.  I know it isn't a
major problem in itself, but I wonder if there might be a temp sensor gone
wonky somewhere, or something.

Any help muchly appreciated.

Cheers,
Albert
