If this is the case in your case, you'll need to replace the connector. Where To Buy The Blower Resistor And Saveįord's blower motor resistor connectors usually are found melted. The circuit descriptions are the same for all of the Ford vehicles covered by this repair tutorial (see the ‘Applies To:’ box on the right column). NOTE: If the color of the wires described above DOES NOT match what's on your particular vehicle, don't worry. The cool thing is that you can check the integrity of each resistor and the state of the thermal fuse with a multimeter and that's how I'll show you how to test it in this tutorial. This reduction in the blower motor's current is the end result of the resistor converting this electrical energy into heat energy and boy does the resistor assembly get hot! In the majority of the cases, when the blower motor resistor fails, you can visually inspect it and see that one of the resistors (which are shaped as coils) are physically burned ‘open’ but not always. The one blower motor speed that doesn't depend on the blower motor resistor assembly is HI since the blower motor switch accomplishes this speed by completely bypassing the blower motor resistor assembly. To be more specific, these resistors reduce the amount of current flowing thru' the blower motor (and thus reducing its speed). The Ford blower motor resistor assembly, covered by this tutorial, has 3 different resistors in series and depending through which resistors the blower motor current is flowing thru' (on its way to Ground) you'll get one of three speeds: LO, M1, and M2.
