I have a 06 Ram. That being said the heater and ac have a mind of their own.If i want to use the defroster only about 50% of the air is directed to the windshield. As holds true with any setting I choose to put it on.The vents get warm/cold air sometimes although not much,some comes out the vents some out the floor and a little out the defroster. Could it be the main control unit and if so how do I go about getting it out to replace it?
