Finaly found out how to have the A/C on "RECIRC mode on" as a default always.
Like some of you had advised I tried hitting the RECIRC button while in AUTO mode, and programming that setting as the driver prefered setting.
As I live in the tropics the temp is usually set to lowest (15 degrees Centigrade).
In AUTO mode this lowest temp setting leads to maximum and near-stereo-muting fan speed.
But finaly (duh!) I found out, if left in AUTO mode and just turning the temp up a bit clockwise (drivers and/or passenger side, this eventually lowers the fan speed without the RECIRC mode disengaging. Tada!
Now when ever I start the engine, the RECIRC button will light up after a few secs without having to push it. Another victory!
PS My A/C cools also very well when the engine is idling. So I don't have to rev it to get better cooling.
