How To Test The Blower Motor Resistor Ford 4 0l Test 1: checking continuity of the blower resistor. test 2: using a jumper wire to bypass the blower resistor. where to buy the blower resistor and save. related test articles. you can find this tutorial in spanish here: prueba: resistencia del motor del soplador (4.0l ford) (at: autotecnico online ). If everything is ok with the blower switch, on the a c heater control panel, the blower motor should run as you bypass each blower speed (in the indicated test steps below). important: use a small diameter wire as a jumper wire or you run the risk of damaging the blower motor resistor connector's female metal terminals.

In this video we go over testing blower motor resistors found in ford vehicles with manual climate control.i only recommend motorcraft blower motor resistors. If it’s good, check for debris on the evaporator or heater. decreased airflow causes the blower motor resistor to overheat and fail. reduced airflow also causes the blower motor to work harder, draw more current and that can cause repeat blower motor resistor failures. the blower motor fuse blows repeatedly. the blower motor is drawing too. Here are some tips on how to test your blower motor resistor: start by looking for the blower fan resistor. a repair manual can tell you where its location is in your vehicle’s make and model. inspect the resistor visually. look for obvious signs of corrosion and burns from overheating.
