About auto heater blower motor, its function is obviously to control the temperature of air. See the complete definition: The blower motor is a fan that pushes heated or cooled air through the instrument panel vents, depending on the climate system settings and selected fan speed. The blower motor is a fan that pushes heated or cooled air through the instrument panel vents, depending on the climate system settings and selected fan speed. Adjusting the fan speed sends a signal through a resistor to the blower motor to speed up or slow down. The blower motor resistor adjusts the amount of current to the blower motor based on the selected fan speed.
When the blower motor fails, only a small amount of air passes through the internal vents, depending on the amount of external air entering the climate system. As insider suggestion, If the fan is not working, before pointing to the blower motor, check the motor fuses to make sure they are still intact. Many vehicles have two fuses for the blower motor, one in the internal fuse box and one under the hood. The blower motor is normally located under the passenger side instrument panel.
