Hi, I have a 406 exec 2001 Y reg. Noticed something strange with the climate control, I think. As the weather has warmed up a little, I have used my aircon and noticed that if I set the temperature very low 14º - 18º the air intake is constantly in recirculation, regardless of pressing or not the recirc button. If I set the temperature above 18º the air starts to come from outside. Is this how it is supposed to work or is there a malfunction. Have looked at the owners manual, but it is a bit confusing. Hope that someone out there can help me out. Many thanks. J. Grilo
