Unidentified Knob

No, not the knob behind the wheel.
I have a control on the lower right of my 2001 4.5LW dashboard that has no knob on it:


Any idea what it might be? Does anyone else have one?

The best the supplying dealer could come up with was "leave it alone - something to do with the air conditioning".

Could this be the thermostat to control the temperature of the aircon output?

Thanks. Do you know exactly what it does?

Oh, and have you got one as well?

Interesting, same dealer spinning different stories ....
