I have a little problem with our new Kia Venga automatic. At the beginning when you go, the Venga heats very quickly to the preset temperature and keeps it perfectly. If you then drive on the highway the air of the side exit nozzles becomes colder after about half an hour, it pulls slightly cold, but is actually warm in the car. A bit unpleasant!! Even if I make the middle nozzles at the climate automatic it comes cold from the small upper side nozzles, we If you want to keep the side panes fog-free! A closing of the nozzles does not change anything… You can regulate, but somehow this is not the purpose of a KA. Only when you adjust the air from the side nozzles so 25 degrees is it suddenly warm and in the car it is no longer possible!! At first everything regulates perfectly and then no more… Is there any key combination to perform a reset or diagnosis of the ventilation valves / air conditioning automatic?? Thank you already Now for your help.
