About the blower motor resistor:
The blower motor resistor is responsible for controlling the fan speeds of the car's heating and air conditioning unit. Common locations are near the blower fan motor, under or behind the dashboard, around the passenger footwell etc. The most common symptom of a failed blower motor resistor is when the heater fan only runs at high speed and doesn't work at low speeds.
