Heater Blower Motor Replacement Service and Cost

Common Misdiagnoses

If you can hear the blower motor operating, but cannot feel air flow from the vents, there is a problem with the airflow controls, not the blower motor.

Common Symptoms

Heater blower motors can be damaged by fluid leaking from a heater core or evaporator. Any fluid leaks near the heater blower need to be resolved or the new heater blower will be ruined.

Best Practices

After the repair, the heater motor should run normally at all speeds and in all modes, such as defrost, heat, etc. The new motor should be quiet and not vibrate.
