Thanks Paul,
Will give it a try on my way home..

Mine was terrible at this when I first took delivery back in September then I noticed the wet feet problem.. and thanks to a post on RRSPORT was directed to look behind the centre console (there's a small panel to the left of driver's footwell) where the rubber drain pipe for the aircon was not connected to the metal drain which passes under the car. Since then (ie. after the car dried out) there have been no steaming up probs..

If you're finding bad condensation on all windows can I suggest checking that your air con isn't draining into the car?

Like most modern HVAC systems in powerful cars like the RRS, the A/C is supposed to be left on at all times. I believe that many of the condensation 'problems' some of you are experiencing would be alleviated by simply leaving the HVAC in 'Auto' mode with A/C at all times.
If you are still experiencing condensation with the HVAC in Auto with A/C turned on, then you may well have the mixer/blender problem that some have noted.

i changed my setting on my heater controls to auto and 22 deg c and left it to do its thing, all the way home from work it was fine not one bit of steamed up window, and then whilst driving about tonight, still ok..
Thanks Paul think this has sorted it.
Won't interfere with the auto system again will leave it to do its thing..
