Rear Aircon

[lexusdaduk]

Had the car nearly 3 months and loving it but some questions remain unresolved even from the dealers and internet searches, i have been playing around with the rear air con and found out 3 things,

and the hand book is less than helpful

1 when on low it blows air to the rear screen, either side of the sub woofer and the temp is cooler than the digital settings

2 high blows through the rear side vents and the temp is cooler than the digital settings

3 Hi and A/C light on makes no difference to the temp when rear temp button pressed but does alter the front digital readout and that temp changes.

I have left the rear blower on low and it looks to keep the rear screen clear on inside mist or when i have 4 adults all breathing buts that's all i can find out at the moment,

It looks to me as though it's for warm/hot days to aid cooling as the heat in the rear is fine supplied from the front and two center rear vents.

anyone got another take on this or any links Regards Mark.
