Erratic HVAC blower motor operation may be caused by a failed blower motor and/or blower motor resistor. Our technicians tell us that if the blower motor resistor fails the blower motor should be checked. If the blower motor fails its functional test in should be replaced along with the failed blower motor resistor.

Fan was becoming erratic and then suddenly stopped. Yet to be fixed.

Blower Motor suddenly went out without warning. Currently looking for a cheaper than dealer place to purchase the Blower Transistor or Heater Control Transistor.
