I think gerrym51
means side Vented windows at the rear, not the glass cargo doors, section
One the rear cargo windows have options plain glass Heated glass and wipers plus security glass.
In the UK there is no power operated windows that refer to the vented ones at least electric sliding windows vented.
I may be misunderstanding the question! The Dodge site uses another language,as to what The Euro vans have.
However I know the Sprinters backwards inside and out, In Europe there is the crew Cab cargo van that has windows for these,but in several formats two piece sliding or upper widow slide there are many versions.
Dodge is to get a newer revised Sprinter IN Spring, windows are mentioned but nothing to indicate what the revision is for.
Mercedes as all Manufactures out source glass supply to the original manufactures that specialize in glass for vehicles, the only difference to these is Mercedes Has a part number stamped on it.
I have included some sketches of what's available I suppose you could call it power vented but it's by the wind updraft they are not power assisted as such
The company that produces these also make the power fans, cargo dividers etc, and vents for Mercedes.
I also find no reference to the power vented rear window on the Dodge option site under window packages 1 11 111and 1V not that I saying they don't exist it maybe a sales advert need more info.
There are two options for Glass where installation is required.
One: order from factory the glass is vacuumed bonded onto the pre formed metal work.
Two: after market fitting of glass requires the metal to be cut from the frame of the vehicles and a seamless rubber surround is required to hold glass in place.
