Yes, it is the manual aircon. What happens is: Aircon (and light) *off* Move fan speed knob, Aircon (and light) comes *on* Turn Aircon *off* Move fan knob to any position, and Aircon comes *on* again. Basically, if I turn the knob at all, the Aircon comes on ;) Hmmm, time to get in touch with the dealer I reckon... :(
