Hi..Love this forum!! I have a 2006, 5.9, Laramie package (not sure if that makes a difference or not). Needed to use the defrost this morning, to my surprise the air directional selector would not take the air from the feet to the defrost position AND I could could not get hot air out when I moved the temp selector over. Fan seems to be working fine, air comes out the floor vents but it always cold. It's odd both stopped working at the same time. Any suggestions?
