Common symptoms of a failing power unit:

No cabin blower operation at all
The fan fails to blow any air through the vents, a sign of complete power loss from the regulator to the blower motor.
Only certain blower speeds work
The fan responds only to specific settings, for example, working only on high or low, with intermediate speeds non-functional.
Erratic cabin blower speed
Airflow varies in intensity or comes out in unpredictable bursts instead of a consistent, controlled speed.
Fan runs constantly
A continuously running fan, even when the car is off, indicates a faulty regulator and can lead to battery drain.
