The Heater Blower Motor is an electrically operated fan that provides airflow into the passenger compartment for the heating and air conditioning systems.

The blower motor helps to deliver warm or cold air into the passenger compartment for the drivers comfort and safety. The blower motor on most vehicles is located underneath the dashboard, on the right side of the vehicle.

Symptoms of Failure

• A failing heater blower motor will often make "squeaking" or "chirping" noises and the noises may change or go away temporarily when changing the fan speed
• If you hear the fan operating, but no airflow is coming from the vents, this indicates a problem with the vent control system
• If the fan operates on high speed only, this indicates a
  possible defective Blower Motor Resistor
