An engine cooling fan runs continuously when an electrical or mechanical fault signals the cooling system to stay in maximum heat-rejection mode, or when the engine is actively overheating. Common triggers include a stuck-closed fan relay, a failing engine coolant temperature sensor, low coolant levels, high air conditioning refrigerant pressure, or a locked mechanical fan clutch.
When you turn on your air conditioning during a humid Michigan afternoon, you expect an immediate blast of cold air to counteract the heat. If your vents are blowing warm instead, the issue typically stems from a breakdown in the refrigeration cycle or an airflow obstruction. At NewGen Chrysler Dodge Jeep Ram of Clinton, we see this most often when a component can no longer maintain the high-pressure environment required to chill the incoming air.
