I Have a 2005 Chevrolet Silverado Extended Cab, this is a nice truck but lack in one thing. I always open the rear windows to allow air to flow freely and not at resistance. It is an extended cab so obvisously I have to manualy open the windows. I would like to convert them to power windows. Does any body know of a GM truck/suv/van that has something i can apply to this or maybe a universal kit?
