My F150 has a temperature dial which I think opens or adjusts a blend door in the air system??? Anyway when I turn the dial to hot there is a slight resistance like you might expect if the cable behind it was hung on the far end. Is this attached to a blend door as I've been told by some reasonably competent floks or to a valve on the heater coil? How do I solve the problem? Thanks - Jeff Jackson
