The air conditioning in the back portion of the van does not seem to be working. The front works fine.
The AC system could be low on refrigerant. Vans that have rear AC hold much more than a standard system. There are however, many more possibilities. Restrictions in the lines and blend door issues could cause this as well. I would have your windows inspected so that the right repairs can be made.
