Subaru Outback blower fan for heat and AC stopped working despite replacing motor and resistor with auto climate control on Subaru Outback

Some Subaru Outback owners report experiencing issues with the blower fan for heat and AC not working, even after replacing the motor and resistor. These problems may stem from a faulty fuse that interrupts the circuit, preventing the blower motor from functioning properly. Additionally, low coolant levels or air in the cooling system can hinder the heater's performance. Some owners also encounter issues due to a clogged heater core, a malfunctioning thermostat, or a faulty blend door actuator, which affects the distribution of hot and cold air. A bad water pump can further impact coolant circulation, while a dirty cabin air filter may restrict airflow, compromising HVAC performance. Lastly, problems with the HVAC control unit can also contribute to blower fan issues. It is advisable for owners to systematically check these components to identify the root cause of the blower fan malfunction.
