Here in Tucson, AZ our temperatures may not drop as low as they do in other parts of the country, or state for that matter, but they do get low enough that driving without a properly functioning car heater can be uncomfortable.

About the Heater Blower Motor

The heater blower motor is located in the HVAC ducts, usually behind the glove compartment. When the heater (or AC) is active, the blower motor will push the desired temperature of air through the vents. When the heater is selected, the blower motor will suck in air and blow it over the heater core which will then provide heat from the vents.

Driving with a faulty blower motor may not make for a comfortable ride for the vehicle’s occupants, but there is no risk associated with continuing to use the vehicle.

Symptoms of a Faulty Heater Blower Motor

If the blower motor fails, you may find that the AC and/or heater still work with cool air or heat coming from the vents. However, the air pressure will have decreased significantly. This occurs at all temperatures and fan speeds.  You may also notice a rattling or grinding noise coming from the passenger floorboard when the heater is active. This sound is a result of broken fan blades, or faulty fan bearing. The sound may come and go, and it may or may not change with the speed of the fan.

A few factors may contribute to a failing blower motor such as:

  • The plastic fan blades will become brittle and break over time.
  • Amount of use. Blower motors fail more frequently in high mileage vehicles. The more it’s used the quicker it can burn out.
  • Dirt and debris in the HVAC box can seriously damage a blower motor, regardless of mileage or age.
