Now that the "mystery hook in the boot" is solved (see Look It's a Hook thread), there's a 2ndunexplainable thing in my car (asides from me).


It's an odd thing behind my steering wheel (really - it's not me!) on the dash board to the right which resembles a kitchen sink plug-hole, or circular airvent of the same size.



Any ideas?

It is part of the automatic air con system (where fitted). There is a little fan behind that draws in cabin air and measures its temperature.

I've got an "auto"setting on my AC - is that the same thing?
