Your heat is cold, because the heater core is blocked. You need to "remove air bubbles" by "burping" system and/or replace heater core. Make sure you are not leaking coolant and add to the max line in reservoir. You can remove some air bubbles by simply opening up the radiator cap a turn, then let the engine warm up. With a warm engine, the fluid will be hot, so you should see steam. That is ok. You want air to come out and fluid to stay in if possible.
You can not "burp" a Villager, the system is not designed that way. Its far more likely they simply have a low coolant level. If the heater core was blocked, the radiator would be as well, and the car would overheat. I've never seen a blocked heater core on a modern car, it's very rare. It's also possible the servo that operates the hot air damper is not working, or the heater control panel switch that controls it is defective.

When the heat is on why would the back vents of a 2004 dodge durango blow cold air and the front blow hot?
The control for the heat on the dash has a control for the back seat and also has a setting that says something like "Rear Control". This allows the passengers in the back seat to control their heat independently via a temperature control in the back seat (on the back of the center console). So you could have the heat on in the front and the rear on "rear control" and if the passenger in the back has set their control to cold, it wold blow cold air in the back even though you have the heat on in the front.
