3.2L V6 model. Digital Climate Control panel. My problem is that my heater will only blow out of the front facing vents. I cannot get it to blow on the windshield to defrost/defog my windshield. I cannot get it to blow out of the floor vents. I can control the fan speed and adjust the temperature. The display changes with each button press to indicate what mode it is now in when I press a different mode as well as a digital "beep" to indicate that I pressed a button. But it won't physically change the origin of the flow of heat.
