About Blower Motor
In the HVAC ducts, the blower motor is traditionally a fan which is usually placed behind the glove box. When the heater or air conditioner on the car is turned on, the blower motor works and forces air through the vents.
What is the purpose of Blower Motor?
The blower motor's primary function is to move air through your vehicle's vents when the heater or air conditioning is turned on. The blower motor blows air through the center of the hot heater when the heater is turned on and sends the hot air through the vents as well as when the air conditioner is turned on it blows air through the cold evaporator and sends cool air to the vents.
How Blower Motor Works?
The operation of blower motor is easy to understand. When supplied to the blower motor, the electrical current spins and in effect causes the fan to spin. Usually, the motor assembly is bolted inside a heater frame, so the fan can blast fairly large amounts of air at high speeds. The blower motor blows air through the heater core when the heater is turned on and when the air conditioner is turned onto the blower motor channels its air to pass through the A / C evaporator instead of the heater core. There are few controls associated with the blower engine, such as speed selector, which allows you to control the engine speed.
Where is Blower Motor Located?
Even though each vehicle is designed and configured a little differently, the heater box typically contains a blower motor in your vehicle. Blower motor is readily accessible in some cars, and hidden under the vehicle's dashboard in others. The heater box and blower motor are located inside the passenger compartment of most cars, but in some cars both the heater box and the blower engine are located inside the engine compartment. Large vehicles such as full-size SUVs are fitted with more than one blower engine, one in the front heater box and the other somewhere in the vehicle's rear.
