Truck has no heat and don't know why. Suffered through it all winter but wanting to get stuff fixed on it now before school starts next fall and have no money for it. Anyone have a ford with this problem? Ac blows cold and heater isn't cold but more just cab temp. I've read blender door, heater core, broken nob, and others. Fixing all of these without first hand knowledge almost seems wasteful. At the same time I don't wanna spend hundreds at the mechanic either.
