Problem overview

Some Ford Ranger owners report experiencing water accumulation in the floorboards, leading to musty odors and potential rust issues. This problem can stem from various causes, such as leaky windshield seals, clogged AC plenum drains, or cracks in the drip rails that allow rainwater to enter. If left unaddressed, this moisture can accumulate and contribute to rust and further damage. Owners emphasize the importance of identifying and fixing the source of the leak, which may involve inspecting the windshield seal and clearing any clogs. Additionally, thoroughly drying out the affected areas is crucial to prevent mold growth and persistent odors. In cases of severe damage or significant corrosion, it is recommended to seek assistance from a water damage restoration professional to ensure proper remediation.
