Our Mercedes work vans all have electric windows that operate as pressed and will dim the lights very slightly if held down when already fully open or closed. The newest (23) van is the only one that does not to do this. When you pulse the button, the window steps about 50mm every time and there is no dimming of lights when at end range. Bear with me now - The wipers have Merc switches (obviously) but the actions are just the same as Fiat right down to the (annoying) double wipe when you use the flick wipe switch. I think they all use the same control modules (probably Bosch) but as the fully electronic window controls are quite new, it's unlikely that Fiat had them on a 2018 Doblo.
