Perform an accurate diagnosis (verify power, ground, and signal inputs)
Verify the HVAC case drain is not restricted (no water or debris in HVAC case)
Replace associated components (connector, blower motor, cabin air filter) to prevent repeat failure
Fully install component in the HVAC case before powering it up and retesting (lack of airflow will burn up the resistor)
