lol, sry, wasnt trying to be a smart "A", just thought I would ask first before assuming it was hooked up...you know the old saying to assume makes an a s s out of you and me...lol Might want to peek up under the dash and look at the cable that goes to the top of the heater box, it has like a coil at the end and just slides down over post. Could have come off. If it is connected, then you may have to pull off the front duct to see if it is moving the flapper door open or closed.
