What is a blower motor on a car?

The blower motor is the fan that pushes heated or cooled air through dashboard vents based on the climate system settings and the fan speed selected. 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 is the main electric motor in the car HVAC system. The purpose of this blower motor is to allowing blowing air to come through the vents by transferring the electrical current. It uses a motor resistor and switch to control the speeds of airflow.
