But if the resistor burns out or wears out from corrosion, there is nothing to reduce the amount of voltage going to the blower motor for the lowest fan speed, so it will most likely get the ...

Adjusting the fan speed sends a signal through a resistor to the blower motor to either pick up the pace or slow it down. The blower motor resistor adjusts the amount of current going to the ...

Simes notes, “Check that the wiring close. Many (defective blower motor resistor modules) will have burned up wiring to the resistor. Some resistors come with (a) new wiring (harness ...
