How to test the blower motor switch in Ford 4.0L?
CASE 2: All circuits tested had continuity where indicated in the test steps. This is good and is the correct and expected test result that tells you that the blower fan switch (in the A/C-Heater control panel) is NOT defective.

What causes a blower fan to stop working?
Since these are mechanical connections the blower switch is making to open and close these circuits, over time and use these contacts become pitted and covered in carbon (from the electrical arching that occurs when the contacts close). When this happens, one or several of the blower fan speeds stop working.
