Hello, this is my first time making a post because i can usually find my problems from other peoples past experiences since it’s such an old vehicle. My Expedition has not had rear A/C for a long time (my dad owned it before i did) and i am having problems pin pointing the problem because it seems that most people don’t have the same package as I do. I have an Eddie Bauer with a sun roof which gives me a rear climate control panel attached to the center console along with the stock radio controls. when you use the controls nothing happens but the front A/C and heat work great. My rear A/C goes to the two small vents shown and the 3rd row which would help circulate cold air throughout the entire vehicle instead of it all coming from the front 4 vents.
