Would an ac heater blower motor resistor stop your ac from working?

Yes, a malfunctioning blower motor resistor can prevent your AC from working properly. The resistor controls the speed of the blower motor; if it fails, the blower may not operate at all or may only work at certain speeds. This means that even if the AC system is functioning, you may not get any airflow, resulting in a lack of cooling. If you're experiencing issues with your AC, checking the blower motor resistor is a good place to start.
