How does an AC blower work?
The more air which flows through the coolant coils, the greater the efficiency of the air conditioner. In this way, blower fans work to aid the heat transfer by sucking the warm air out of the room to blow over the coolant, maximizing the quantity of airflow.
What is a blower motor?
The blower motor in your car is tasked with rotating the AC and heater blower fan. It helps to push air through the system of ducts and evaporator or heater core, thereby controlling the car cabin climate. To achieve that, the blower motor assembly consists of a 12V DC motor and fan wheel. The motor receives current from the car battery, energizes, and spins together with the wheel. This helps to move air into the passenger cabin through the AC vents.
How much does a blower motor cost?

What are the problems with blower motors?
Blower motor problems are either mechanical or electrical. Mechanical faults include wear, clogging by debris, and broken fan blades. Electrical issues involve the power circuit and include blown motor, bad wire harnesses or cables, and damaged resistors. The motor also develops problems if a fuse is blown, a relay faulty, or the control module bad. Worn parts of a blower motor such as motor brushes are replaceable, while cleaning the fan fixes jamming problems. Other parts that you can replace are fuses, relays, connectors and resistor.
Why do blower motors need resistors?
Blower motor resistors help to vary the speed at which the motor rotates. This allows different speed settings for the AC system. The resistors work by controlling the amount of current that goes to the motor. A blower motor resistor is one of the components that go bad, mostly due to overheating or corrosion. When that happens, you may find that the blower motor only runs at the highest speed. At this speed, the motor’s power system bypasses all the resistors.
Where is the blower motor located in a car?
Many cars use a single bower fan to operate the air conditioning and heating system. This is usually sufficient. However, some cars, especially SUVs, use an additional blower motor mounted in the rear. The two blower motors offer a more efficient HVAC system or cabin climate control. The front blower motor is usually located behind the glove box or under the dash. In some cars, it’s mounted in the engine bay.

Why does my blower motor fail?
The main cause for blower motors failing is that dirty air passed over them and stopped up the vent hole, causing the motor to overheat .
How do compressor motors work?
Compressor motors are really two motors in one: the start motor and the run motor. They just happen to be connected together at the common wire terminal. The start windings are very small wires that are wound on the motor to deliver a quick burst of power and start the motor. Since the start windings are only designed for the initial spark. if the start windings have to work for more than about three seconds, they’re likely to burn out. The motor’s run capacitor ensures the start windings don’t work too hard and keeps the entire motor running correctly.
