This HVAC blower motor wheel may need replacing if you hear rattling, ticking or scraping from the blower, feel vibration at the fan, or notice weaker airflow from the vents while the motor still runs. A cracked, loose or unbalanced wheel can cause these signs, but other HVAC faults can too, so diagnose the cause before replacing.
