Ford Expedition rear screeching noise, clicking mirrors after unlocking, and water in passenger side floorboard issues on Ford Expedition

Some Ford Expedition owners report experiencing a screeching noise in the rear, which may indicate a faulty blend door actuator responsible for controlling airflow and temperature. This noise can often be pinpointed by listening near the plastic trim over the passenger rear wheel. Additionally, some owners have noted clicking sounds from the mirrors after unlocking the vehicle, potentially stemming from a malfunctioning motor or gears within the power mirror assembly, necessitating professional inspection. Furthermore, water accumulation in the passenger side floorboard is reported, commonly caused by leaks from damaged weather stripping, clogged sunroof drains, or faulty door seals. It is crucial for owners to address these issues promptly to prevent further damage and maintain the vehicle's comfort and functionality. If problems persist, consulting a certified mechanic or dealership is recommended for a thorough diagnosis.
