Ram 1500 cabin fan not working despite replacing all components on Ram 1500

Some Ram 1500 owners report experiencing issues with their cabin fan not working even after replacing all components. These owners often find it necessary to check the power supply to ensure the fan is receiving adequate power, as a failure to do so can prevent operation. Additionally, some have noted that tapping the blower motor or inspecting ground wires for corrosion may temporarily resolve the issue if the motor isn't functioning. Testing the control module with a multimeter is another step that some owners take to determine if it is faulty, and replacing the temperature control or fan speed control switches may also be required if they are not operational. In cases where the HVAC control module is defective, owners may face replacement costs ranging from $200 to $600. If the fan continues to malfunction after these troubleshooting steps, consulting a professional mechanic is often recommended to diagnose and rectify the underlying problem effectively.
