The heater blower motor resistor is typically located near the blower motor itself, often in the HVAC (heating, ventilation, and air conditioning) system's ductwork. It consists of a series of resistors that create different levels of electrical resistance to control fan speeds. When you adjust the fan speed using the control knob in your vehicle, the resistor regulates the amount of voltage sent to the blower motor, resulting in varying fan speeds. There are a few common signs that indicate ...

What is a Throttle Body? The throttle body is a part of the air intake system in a car's engine that controls the amount of air entering the engine. It is usually located between the air filter and the intake manifold and consists of a butterfly valve that opens and closes based on the driver's input via the accelerator pedal.
