Hello! I am new here. I have an older problem. I saw the same problems on the internet with several car brands, but I couldn't find a solution. I have a Ford Tourneo Connect (2015) and I think the indoor air circulation is not working well. I've been to several service centers, but they couldn't help... The car has automatic air conditioning. If I want the bad air to stay outside, for example in the city, and I press the recirc button, it turns off after a very short time. (Whichever way the air is directed.) And I have to turn it on again and again. It does not automatically switch back even in automatic mode. I think this is a very dangerous process. In the summer, when the outside temperature is high, the switch remains inside in the internal circulation position.
I also don't understand why Ford disables the A/C when the temperature outside is around zero degrees Celsius. In such cases, I used the air conditioner in my older cars for dehumidification in the winter and it worked excellently. You can read on the internet that, supposedly for reasons of life and accident protection, Ford switches off the internal circulation with a sensor so that the air does not run out and the windows do not fog up. If so, how does fresh air get into the car when the air conditioner is turned off? No way! (Unless you roll down the window...) In this case, the incoming vent is not open. In this case, in winter, when the air conditioner is turned off, the warm air from the radiator does not reach the passenger compartment and fogging starts because the fan does not work either... Is there anyone who can give me advice on my problem?
