i have a 07 ext tb, it has two separate actuator issues i believe. the first is under the armrest, after about 3 or 4 minutes of the truck running this one clicks about 15 or so times then when it quits we have heat or air in the rear, i know it needs replaced but the picture on the other site was taken down so i need a part number.

the second problem is when the heat is on the over head vents blow out freezing cold air and the floor vents blow hot, i have also noticed a steady dripping under the truck like when the ac is running in the summer. could this be caused by an actuator possibly not turning off the ac? or should i look elsewhere on this issue, its getting horrible running the heat on full blast to keep kids in the rear warm.... thanks for any help anyone may have.
