Honda Accord blower motor failure after intermittent noise, replaced at 39k miles on Honda Accord

Some Honda Accord owners report experiencing blower motor failures after intermittent noise, even after replacing the motor at 39,000 miles. These issues can often be attributed to several common causes, including a blown fuse, which may prevent the AC fan blower motor from functioning. Additionally, a bad relay can lead to similar blower motor problems. Some owners find that a malfunctioning blower motor resistor or control module can also stop the blower motor from working altogether. Low refrigerant levels are frequently reported as a cause of AC system issues, while a failed blower transistor may result in the heater fan not operating. Electrical problems, such as faulty connectors or broken wires, can further contribute to blower motor failure. Lastly, defective blend doors may also be implicated in air conditioning problems. It is advisable for owners to seek professional inspection and diagnosis to address these issues promptly and ensure the efficient operation of their vehicle's AC system.
