We are having trouble with the air conditioner in our minivan. If we turn on the air only in the front of the van, it seems fine. But if we turn on the air to the rear of the van, it stops cooling and only blows hot air. Any ideas of what could be the issue?

It sounds like the system is low on refrigerant. Here is a guide and video on how to charge the system:
