Heater Blower Motor Resistor

A blower motor resistor or a blower motor control module is the part that controls the speed of the blower motor.

Heater blower motor resistor. If your blower is stuck on a single setting or has some settings on which it is non operational that means your blower motor resistor may be broken. The motor that runs the fan in the heating and air conditioning system in a car is called a blower motor. When you adjust the fan the heater blower motor resistor allows the fan to run at several different speeds. The heater blower motor resistor is an electrical component that is located between your car s ventilation fan or blower and its power source.

It s located inside the dash often on the opposite side of the steering wheel or inside the engine compartment on the firewall. The blower motor resistor is an electrical component that is a part of the vehicle s heating and air conditioning system. Your vehicle s blower motor resistor controls the speed of your blower motor. It is responsible for controlling the blower motor s fan speed.

When fan speed is changed via the knob on the instrument cluster the blower motor resistor changes setting which changes the speed of the blower motor. When you turn a knob to produce more air flow for heat or cool air the resistor adjusts the electrical resistance to control the power sent to your blower motor.
