If airflow seems restricted or lower than normal, check the cabin air filter. This means that the current running through the blower motor, and thus is speed is controlled by the resistor value. Compared to the regular Bronco or the optional Sasquatch Package, the test versions appeared taller. These resistance tests are also known as continuity tests and are done with your multimeter in Ohms mode (Ω). Nissan and Subaru as well as Chevy and Ford … Now to be a bit more specific, to achieve LO or M1 or M2 blower motor speeds... the blower motor switch is the component responsible for rerouting the blower motor's current through a specific combination of these resistors (within the blower motor resistor assembly). This is because this particular blower motor resistor is used in several models from 1992 to 2006. GM  |   Hiya! Visually inspect the blower motor resistor block and connector for burn damage and severe corrosion. Inspect the resistor visually. Ford blower motor resistor problems remain the most common solution to interior fan malfunctions on Ford cars and trucks. This means that the current running through the blower motor, and its’ speed is therefore controlled by the resistor value. Place a voltmeter across the two pins. If continuity is not present where indicated in the test steps above then this confirms that the blower motor resistor is bad and needs to be replaced. The purpose of these resistors is to reduce the amount of the blower motor's current that's passing through them (as you're probably already aware, these resistors are located between the blower motor and ground).
