Have A6 Avant 2.7tdi 2007. Lights on heater module (front and rear screen, heated seats, climate control, air recirculation) at bottom of centre console have gone out. Controls still work (sort of), although the windscreen booster fan seems a little slower than I remember and the climate control doesn't seem to be working (cabin seems to get very warm and turning to low doesn't reduce temperature).

I've looked at the fuses (right hand side) and they seem fine.

Any thoughts?
