A common indicator of a malfunctioning blower motor is inconsistent airflow. When the blower motor is not operating properly, it can lead to fluctuations in the amount of air being circulated throughout the heating or cooling system. This inconsistency can manifest as weak airflow from the vents, areas of the space that feel warmer or cooler than others, or insufficient temperature control, indicating that the motor is unable to effectively drive the air through the ducts.

In contrast, low noise levels can sometimes indicate a normal operation of a well-functioning motor, whereas a malfunctioning blower motor might actually produce unusual sounds due to strain or failure. High energy bills could arise from various system inefficiencies, but they are not a direct indication of a blower motor issue specifically. A warm ambient temperature may suggest other HVAC issues, but does not distinctly point to problems with the blower motor itself. Thus, inconsistent airflow directly relates to the performance of the blower motor, making it the most accurate indicator of potential malfunction.
