Mazda 6 interior lights, radio, and AC continue running after engine shutdown on Mazda 6

Some Mazda 6 owners report experiencing issues where the interior lights, radio, and AC continue running after the engine has been shut down. This problem may be attributed to faulty door switches that fail to register when the doors are closed, causing electrical components to remain active. Additionally, a blown fuse, particularly the "room fuse," can lead to intermittent functionality of the radio, interior dome lights, and power locks. Some owners also find that electrical grounds, especially those located in the front wheel well, may have poor connections, resulting in unexpected electrical anomalies. To address these issues, it is recommended to check the door switches for proper operation, inspect and replace any blown fuses, and clean the electrical grounds to ensure secure connections.
