4 Signs of a Bad Heater Blower Motor
Your car’s air conditioning and heating systems have many components that support proper functioning. When just one component breaks down, the entire system can become inefficient. In order to keep your car’s cabin comfortable all year round, it is important to ensure all components within your air conditioning and heating system are in good repair.
What is a Heater Blower Motor?
A heater blower motor is a component within your car’s heating and cooling unit that pushes warm or cold air through the dashboard vents. When the heater blower motor breaks down, this could make for an uncomfortable ride. Check out these four signs of a bad heater blower motor.
1. Inadequate Airflow Through the Vents
If you notice little or no airflow coming from your car vents, you likely have a failing heater blower motor. When the heater blower motor is damaged or worn out, it will not generate sufficient airflow for efficient heating or cooling.
2. Unusual Noises or Vibrations When the Fan is Running
If you hear unusual noises such as rattling and grinding, or notice vibrations within the dashboard or interior trim, you could have a bad motor blower heater. However, these symptoms could also be caused by fluid leaks, a damaged impeller blade, or even debris in the motor so it’s best to have you car looked at by a professional mechanic.
3. Defroster Does Not Clear Glass Well
If your defroster does not clear your windshield well, it could be a sign of a faulty heater blower motor. This can make it difficult and unsafe to drive, so it’s essential to have a professional mechanic make any needed repairs as soon as possible.
4. Smoke or Burning Smell Coming Out of the Vents
A damaged heater blower motor can also cause smoke or a burning smell to come out of your vents. If this happens, it is best to keep your heating and air conditioning system off and have the issue repaired as soon as possible.
