Every once and a while ill cold start the truck (3.0L 5speed 4x4) and it'll get up to normal operating temp. Then ill notice that there still is'nt any heat comming out of the heat vents. So then i pop the hood and pull the vacumn line off of that thing (forgot what its called) between the heater hose and i hear a short "pssst" noise, that little valve thingy opens and ta-da I have heat. What the hell is causing this??
