Roof Lighting console

[hawkeye357]

I have just replaced my cars Ariel, can anyone tell me what looks like a little fan is, that is in the roof lighting console of my D8 2.1 td glx estate, it is situated next to the map light ? . Can not find any reference to it in the owners or Haynes manuals, all help gratefully received.

Steve is right it's a 'sample' fan pulling a sample of cabin air across a sensor to give readings back to the climate ECU with regards to the main fan speed and temperature control. The other sensor is a sunlight intensity sensor at the bottom of the windscreen (dash).

They do get caked up after a few years so worth cleaning it - this action can also revive a seized one too!
