I did recharge the refrigerant, check the pressure is OK. But only work for the back of the van, not in the front. What could be the problem.
(1) Answer
My van did the same thing, only the front stopped working and the back was ok. Upon advice of a friend I added more freon and it took a certain amount to get the front to start working again.....looking at the repair manual, the front has a valve that the rear does not so it seems the front requires more pressure to work properly. I would suggest you try adding some more freon.
