Oké. So if I understand correctly it's not a separate switch at the end of the scale at the drivers side. So if the switch itself is broken it also diconnects the path to the auto setting. Now you point that out it makes sense in the drawing of the part.
But than why is the driverside working like it should but the passinger side is not. Uncontrolable are the airvents to the front window. Defrost position as it seems. I had them blocked with tape in summer. There was no way I could switch it of. Does it make any sense to you?
I just looked at the valves. They are worn but not fallen apart so they have to work. Maybe leeking a little bit but that should not be the reason the temperature is extremely high.
Henk.
