SOURCE: 2002 Dodge Ram pickup heater and defroster blows
sounds like it could be a mode door actuator problem which directs the flow of air in the heater case,

If this is dual climate control, which I am sure that it is. Then the actuator for the driver side vents on the heater core is not working. It could be a bad actuator, or a bad controller. If it is a bad actuator then the actuator has to be replaced. It is located down by the passengers feet in the duct work. If it is the controller it is going to be more expensive. The controller is where you select where you want the air to blow (defrost, vent, or floor.)

Not sure about your dodge, but on hondas there is a lever under the driver side vent to allow fresh(outside air) when its cold out, it will be cold, even with the heat on inside, so check to see if your has that lever somewhere on that side...hope that helps
