What is a Heater Blower Motor Resistor?
The heater blower motor resistor is a component in your car's HVAC system. Its primary function is to regulate the flow of Electrical current to the Heater Blower Motor. The amount of electrical current that flows to the heater blower motor affects how fast the blower motor spins. That, in turn, determines how much air flows through the Vents into the cabin of your car.
In short, the heater blower motor resistor is responsible for regulating the speed of the blower motor, which controls how much heat or air conditioning flows into the cabin of your car. Resistors are Electrical components that help regulate the flow of electricity in a circuit. In most cases, they don't last as long as the car does. Over time, they can get worn out or damaged, which can cause problems with the car's Electrical System.
