When the blower motor will only work on the highest setting, this is the tell-tale sign of a faulty Blower Motor Resistor. The resistor is accessed from under the passenger's side dash. Carefully inspect the electrical connector and wire harness for any loose, broken or damaged wires. If the visual inspection checks ok, replacing the resistor will solve the problem. Unplug the electrical connector and remove the 2 mounting screws to remove. For an image location view, click here: https://www.dropbox.com/s/37lb53i6q7rxntj/f150-res.jpg?dl=0
