The blower motor is the fan that pushes heated or cooled air through dashboard vents based the climate system settings and the fan speed selected.
Adjusting the fan speed sends a signal through a resistor the blower motor to either pick up the pace or slow it down.
The blower motor resistor adjusts the amount current going to the blower motor based on the selected fan speed.
When a blower motor fails, only a small amount of air come through the interior vents based on the amount of outside air entering the climate system.
If the fan work, before pointing the finger at the blower motor, check fuses for the motor to make sure they’re still good.
